Importantprecautions

The proposed cable run should be pre-surveyed to deter-mine the terrain and field conditions that will be encoun-tered in the lashing operation. Among those factors to beconsidered (not by limitation) are:(a) vehicle & pedestrian safety (b) condition of poles, anchors, guys and strand (c) proper bonding and grounding of strand

and attachments (d) obstructions such as trees, limbs and

drop wires (e) clearances and separations on poles shared by

other utilities (f) clearances over roads, driveways, walkways

and crossings Protect your work site with advance warning devices atstrategic points to warn traffic and pedestrians of theobstruction in the area. Check your machine first! Prior to using the machine, check that it is in good repair,that all of the parts and mechanical assemblies are intactand in good working order. If the machine has not beenproperly maintained it may well be unsafe to use and poseunnecessary risk to the user. GMP Lashers can be profes-sionally repaired and/or overhauled at the factory withquick turnaround and minimal downtime. Use the proper safety equipment! Before working aloft, inspect all your climbing and safetyequipment to make certain it is in good repair. And whileyou are aloft, ALWAYS wear a body belt with a safetystrap securely attached to help prevent you from falling. Also, you should always raise and lower your lasher onlywith a proper aerial handline (such as our 68590 or08192) or a truck lift. Use the bridle assembly at pole transfers! When transferring the lasher around a pole or otherobstruction, use the bridle assembly as a tether to preventdamage to the machine in case it is dropped. This alsoallows you to concentrate on your own safety first ratherthan the safety of the machine.

Note: Do not set the lasher vertically on the rear gate toavoid damage to the spring catches.1. Remove the four screws holding the gear housing

cover and remove the cover.2. Position the lasher with the gear housing facing to the

right and the rear gate to the left.3. Remove the three #10-25 filister head screws which

will allow the complete strand tension roller assemblyto drop out through the bottom of the gear housing.

4. Reinstall the gear housing cover and your G lasher is now capable of over-lashing cable(s) up to thecapacity of the machine.

Note: Be sure to save the parts. To reinstall simply reversethe above procedure.When placing the lasher into its case, have the front cablelifter assembly open and put the rotor assembly in thelocked position. Keep the lasher in the carrying case at alltimes when not in use. Lubrication advice The gears of the G Lasher are lubricated at the factory witha specially formulated graphite-based lubricant. This lubri-cation will last indefinitely provided that the gear housingis left unopened and uncontaminated by solvent or debris. If, during the course of your G Lasher’s service life, it isever returned to the factory for repair and reconditioning,it will receive a thorough cleaning during disassembly andwill be freshly relubricated as it was when new. Do notattempt to lubricate the gears as improper lubrication cancause eventual slippage due to lubricant flowing to othersurface areas during operation. The only parts whichshould require occasional lubrication with S.A.E. 10 or 20motor oil, are the threads of the rear cable lifter and hingesto keep them operating freely. Wipe off any excess oil.Repairs & maintenance From time to time it may be necessary to make minor fieldrepairs; the following list of parts will prove helpful inordering what you need. However, nobody can give yourlasher as thorough a check-up as the people who builtit...GMP. Our experienced technicians will check everydetail, thoroughly clean and re-lubricate your machine andput your lasher back in like-new shape within 10 workingdays, guaranteed. Just call the factory for full details onour lasher maintenance program.

Look at your G Lasher for a moment. You will see it consists of a rotating drum supported on a carriage; thestrand and cable pass through this carriage during the lashing operation.As you look at the carriage, you will see it also has a forward direct gear drive mechanism, cable and strandrollers, front and rear gates, various pulling eyes and ananti-backroll brake. The major components are made of heat-treated, high-strength aluminum alloy, bronze, stainless or zinc-platedsteel. Sealed aircraft-type, dust-proof ball bearings are onall shafts and the drum, with other moving parts mountedon Oilite bushings. At about 71 lbs. (32 kgs) without wire, your machine’sweight and features give it an optimal strength-to-weightratio for the heavy-duty work of lashing large telephonecable(s) or electrical distribution cables.Cable capacities The G Cable Lasher can be used for securing aerial cablefrom about 21⁄2 in. up to 5 in. (65 - 125 mm) diameter tosuspension strands from 3⁄8 in. to 3⁄4 in. (9 -19 mm) diame-ter with a spiral lashing of .065 in. (1.65 mm) stainlesssteel lashing wire. (A modification for .045 in. / 1.1 mmstainless steel wire is also available.) The G Lasher has the capability of lashing any number of cables to a singlesuspension strand provided that the entire diameter of thecable bundle not exceed 5 in. (125 mm).

7. Pull out sufficient lashing wire for termination andclamp the lashing wire to the strand at least 12 in. (30 cm) behind the lasher.

8. Close the front gate assembly. Remove the tow linesnap hook from the strand and attach the snap hookto the other tow eye of the lasher.

9. The lasher is now prepared to lash cable. Transferring the lasher around a pole or other obstruction

1. Before transferring around a pole, temporarily termi-nate the lashing wire near the pole with a lashing wiregrip, pull out sufficient wire for the final terminationand the cut.

2. Open the front gate all the way.3. Move the lasher forward or backward along the strand

until the drum locks.4. Attach one of the lasher bridle snap hooks to a lasher

towing eye on the front of the machine. Now pass thebridle under the strand, past the obstruction and attachthe other snap hook to another lasher pulling eye.

5. Press down the strand tension roller lever and turn itclockwise to disengage it from the strand.

6. Raise the lasher from the strand and transfer themachine to the strand in the next span following theinstructions beginning in step 5 of the preceding section.

Instructions for over-lashingWhen lashing a cable or cables to an existing cable thesame procedure is followed with one exception. The strandtension roller assembly should be removed so as not tointerfere with existing lasher cable. This is a simple proce-dure which should only be attempted while on the groundand working on a suitably stable work surface.

GMP G Lasher

Lashing wire magazines & capacities The lasher has two magazines for loading of lashing wire;each can hold a coil of .065 in. x 450 ft. (1.65 mm x 137 m)wire. Note: .045 in. x 1200 ft. (1.1mm x 365 m) coils maybe used as an alternate. Each magazine has two rollers forguiding and tensioning wire during lashing. The wire coilsare held stationary in the magazines, with the wire feedingfrom the center of the coil eye through a throated hole andover a guiding roller; it is then threaded around the rollersand wound onto the cable/strand bundle.Your lasher can use a single wire or two wires simultane-ously (often called “double-lashing”) wherever extrastrength is desired. Unlike other machines, the balance ofa GMP lasher is not adversely affected by the amount ofwire loaded in either magazine. There are two rubber strand drive wheels mounted in theforward part of the machine in the drive housing andgeared directly to the rotatable drum. A smaller trailerwheel located in the rear of the carriage supports the rearend of the lasher on the strand. Maximum traction is pro-vided by forcing the strand into the groove of the two rub-ber drive wheels by means of a tensioning device actuatedthrough a system of levers. This feature provides uniformtraction regardless of the angle between the pulling lineand the strand. Adjustable rear gates & cable lifter The rear cable lifter rollers are adjustable vertically toaccommodate cables of various diameters and are held inthe open position by a spring catch on each side. To openthe rear cable lifter loosen the bottom knurled knob suffi-ciently to swing free. Swing both gates open until thespring catches are engaged. DO NOT force the gates openpast the point of engagement of the spring catches toavoid deforming the springs.To adjust the rear cable lifter, open the rear cable lifter,and loosen the bottom knurled knob sufficiently to swingfree. Raise or lower the cable lifter rollers on each side byturning the knurled knobs at the top of each verticaladjusting screw until the desired height is obtained.Observe that the rollers are in proper alignment and swingthe bottom knurled knob up into the closed position andtighten securely.

10

Placing the lasher on the strand 1. Open the rear cable lifter, adjust it to its lowest

position and close it.2. The strand tensioning roller assembly should be in the

open position, placed against the side of the aluminumhousing. This is done by depressing the lever projectingup through top of cover of gear unit and turning itclockwise to the open position.

3. Attach a handline to the strand and to the lasher handle and raise the lasher to the strand by means of the handline.

4. With the machine at the required height, open the rearcable lifter past the spring lock and place the lasher onthe strand. Also, attach one of the snap hooks on thelasher tow bridle (rope) to a pulling eye and the otherhook to the strand as a tether.

5. Engage the strand tension roller assembly by pressingthe lever all the way down and turning it counterclock-wise, allowing it to rise. When the strand tension rollerassembly is in the engaged position, the end of its sup-porting casting is engaged in the grooved guide on theinside of the gear housing.

6. Raise the cable to the strand (by hand), close rear cable lifter and let the cable rest on the rollers.Estimate the amount the rollers should be raised to elevate the cable to within 1⁄4 in. (6 mm) of thestrand. Lift the cable slightly (by hand), open thecable lifter, lower the cable clear of the opening andturn the adjusting knobs on top of the threaded postsuntil the lifter is raised the desired amount. Raise thecable (by hand) and close the lifter.

Front gate & pulling eye The front cable lifter or gate is opened by releasing a latch.When in the open position, this locks the drum automati-cally when its cable slot registers with the slots in the car-riage. The drum is free to revolve when the front cablelifter is closed. The rear cable lifter is held in the openposition by means of spring catches on each side. There are two pulling eyes located forward of the frontcable lifter. These eyes also function as the connectionpoint for the towing bridle when used as a tether to pre-vent the lasher from being accidentally dropped whiletransferring around a pole or other obstruction. Strand tensioning mechanism The strand tensioning mechanism works through a systemof levers. When engaged and locked under the strand, itprovides uniform traction through a wide range of pullingline and strand angles.Automatic brake The anti-backroll brake is a ratchet device which operatesautomatically when the lasher stops and tension is removedfrom the towing line, and is released when towing isresumed. It is not necessary to maintain tension in the tow-ing line when the lasher is not in motion. The automaticbrake will be released when the towing eye assembly ispressed toward the rear of the lasher. To move the lasherbackwards, first clamp the lashing wire to the strand. If thelasher is within reach, release the brake by pushing backagainst the towing assembly. If it is not within reach andthe towing line is attached to the towing eye assembly,release the brake by pulling back on the towing line. Whenthe towing line is attached to one of the pulling eyes on thefront of the gear housing a separate line attached to thetowing eye assembly may be used to release the brake.

As we stated in the beginning of this book, you shouldNEVER operate a lasher unless you’ve been properlytrained in advance, or are being directed by a properlytrained linesperson who is responsible for your work.However, you should find this section of the book helpfulin remembering the right sequence of steps to take inusing your lasher.

Using yourG Lasher

Preparing a lashing wire coil1. Remove the lasher from its case. Remember! It weighs

71 lbs. (32 kgs).2. Cut and remove the coil binding holding the looped end

of the wire at the coil eye or center (inside end) of coil.3. Cut and remove two opposite bindings. Do not cut the

other two bindings.4. Pull out the looped end of the wire until the first turn

is tight against the binding, and cut off the loop. Pullout about 12 in. (30 cm) of wire from the inside of thecoil. The loose end should come out of the face side of the coil.

1. Before transferring around a pole, temporarily termi-nate the lashing wire near the pole with a lashing wiregrip, pull out sufficient wire for the final terminationand the cut.

2. Open the front gate all the way.3. Move the lasher forward or backward along the strand

until the drum locks.4. Attach one of the lasher bridle snap hooks to a lasher

towing eye on the front of the machine. Now pass thebridle under the strand, past the obstruction and attachthe other snap hook to another lasher pulling eye.

5. Press down the strand tension roller lever and turn itclockwise to disengage it from the strand.

6. Raise the lasher from the strand and transfer themachine to the strand in the next span following theinstructions beginning in step 5 of the preceding section.

Instructions for over-lashingWhen lashing a cable or cables to an existing cable thesame procedure is followed with one exception. The strandtension roller assembly should be removed so as not tointerfere with existing lasher cable. This is a simple proce-dure which should only be attempted while on the groundand working on a suitably stable work surface.

Note: Do not set the lasher vertically on the rear gate toavoid damage to the spring catches.1. Remove the four screws holding the gear housing

cover and remove the cover.2. Position the lasher with the gear housing facing to the

right and the rear gate to the left.3. Remove the three #10-25 filister head screws which

will allow the complete strand tension roller assemblyto drop out through the bottom of the gear housing.

4. Reinstall the gear housing cover and your G lasheris now capable of over-lashing cable(s) up to thecapacity of the machine.

Note: Be sure to save the parts. To reinstall simply reversethe above procedure.When placing the lasher into its case, have the front cablelifter assembly open and put the rotor assembly in thelocked position. Keep the lasher in the carrying case at alltimes when not in use. Lubrication advice The gears of the G Lasher are lubricated at the factory witha specially formulated graphite-based lubricant. This lubri-cation will last indefinitely provided that the gear housingis left unopened and uncontaminated by solvent or debris. If, during the course of your G Lasher’s service life, it isever returned to the factory for repair and reconditioning,it will receive a thorough cleaning during disassembly andwill be freshly relubricated as it was when new. Do notattempt to lubricate the gears as improper lubrication cancause eventual slippage due to lubricant flowing to othersurface areas during operation. The only parts whichshould require occasional lubrication with S.A.E. 10 or 20motor oil, are the threads of the rear cable lifter and hingesto keep them operating freely. Wipe off any excess oil.Repairs & maintenance From time to time it may be necessary to make minor fieldrepairs; the following list of parts will prove helpful inordering what you need. However, nobody can give yourlasher as thorough a check-up as the people who builtit...GMP. Our experienced technicians will check everydetail, thoroughly clean and re-lubricate your machine andput your lasher back in like-new shape within 10 workingdays, guaranteed. Just call the factory for full details onour lasher maintenance program.

Look at your G Lasher for a moment. You will see it consists of a rotating drum supported on a carriage; thestrand and cable pass through this carriage during the lashing operation.As you look at the carriage, you will see it also has a forward direct gear drive mechanism, cable and strandrollers, front and rear gates, various pulling eyes and ananti-backroll brake. The major components are made of heat-treated, high-strength aluminum alloy, bronze, stainless or zinc-platedsteel. Sealed aircraft-type, dust-proof ball bearings are onall shafts and the drum, with other moving parts mountedon Oilite bushings. At about 71 lbs. (32 kgs) without wire, your machine’sweight and features give it an optimal strength-to-weightratio for the heavy-duty work of lashing large telephonecable(s) or electrical distribution cables.Cable capacities The G Cable Lasher can be used for securing aerial cablefrom about 21⁄2 in. up to 5 in. (65 - 125 mm) diameter tosuspension strands from 3⁄8 in. to 3⁄4 in. (9 -19 mm) diame-ter with a spiral lashing of .065 in. (1.65 mm) stainlesssteel lashing wire. (A modification for .045 in. / 1.1 mmstainless steel wire is also available.) The G Lasher has the capability of lashing any number of cables to a singlesuspension strand provided that the entire diameter of thecable bundle not exceed 5 in. (125 mm).

Importantprecautions

The proposed cable run should be pre-surveyed to deter-mine the terrain and field conditions that will be encoun-tered in the lashing operation. Among those factors to beconsidered (not by limitation) are:(a) vehicle & pedestrian safety (b) condition of poles, anchors, guys and strand (c) proper bonding and grounding of strand

and attachments (d) obstructions such as trees, limbs and

drop wires (e) clearances and separations on poles shared by

other utilities (f) clearances over roads, driveways, walkways

and crossings Protect your work site with advance warning devices atstrategic points to warn traffic and pedestrians of theobstruction in the area. Check your machine first! Prior to using the machine, check that it is in good repair,that all of the parts and mechanical assemblies are intactand in good working order. If the machine has not beenproperly maintained it may well be unsafe to use and poseunnecessary risk to the user. GMP Lashers can be profes-sionally repaired and/or overhauled at the factory withquick turnaround and minimal downtime. Use the proper safety equipment! Before working aloft, inspect all your climbing and safetyequipment to make certain it is in good repair. And whileyou are aloft, ALWAYS wear a body belt with a safetystrap securely attached to help prevent you from falling. Also, you should always raise and lower your lasher onlywith a proper aerial handline (such as our 68590 or08192) or a truck lift. Use the bridle assembly at pole transfers! When transferring the lasher around a pole or otherobstruction, use the bridle assembly as a tether to preventdamage to the machine in case it is dropped. This alsoallows you to concentrate on your own safety first ratherthan the safety of the machine.
