Specifications
UPPER REVOLVING FRAME:All-welded, precision machined, robustconstruction. A machined surface providedfor mounting load hoist and boom hoistassemblies, and mounting itself on turntablebearing. And pins bail frame with a 12-sheave machinery and single center sheaveof a 21.0 D/d ratio for 2×12-part boom hoistreeving.
TURNTABLE BEARING WITH INTERNAL SLEWING GEAR:Heavy duty, single shear ball type; inner raceof turntable bearing with integral, internalswing (ring) gear bolted to lower frame, andouter race of turntable bearing bolted to upperrevolving frame.
CONTROL SYSTEM:System contains two sets of triplicate tandemvalves which direct oil to various machinefunction and are actuated by control levers viaremote controlled hydraulic servo for allmotions. Working speeds can be preciselycontrolled by motorcycle type throttle andpilot-operated arm chair single axis controllevers in cooperation with “EPC” controllerthat varies engine rpm and hyd. pumpdischarge simultaneously, or varies just hyd.pump discharge while keeping engine rpm viamotorcycle type grip throttle. System alsotakes a specially-tailored unique hydrauliccircuit to maximizes drum horsepower, andreduces horsepower loss with eliminating thepossibility of engine stall.
Pump control system — By “EPC” controller thatprovides two modes of engine-pump control.MODE I:The “EPC” Controller is normally programmedto vary the engine speed and pump dischargesimultaneously. Simply twisting the gripadvances the engine to maximum speed andthe hydraulic pumps to maximum flow at thesame time. This mode is suitable to precisioncrane work.MODE II:By activating a switch, it is able to vary justthe pump discharge by means of the gripthrottle, while keeping engine speed fixed.Mode II is convenient for operations such aslifting magnet and bucket work, where theengine is normally run at full throttle.

Notes — Liftcrane capacities1. Capacities included in these charts are the maximum
allowable, and are based on machine standing level on firmsupporting surface under ideal job conditions.
2. Capacities are in metric tons, and are rated in accordancewith European EN13000 Standards in terms of machinestability and structural strength limitations; the figuressurrounded by bold lines are based on factors other thanthose which would cause a tipping condition.
3.Capacities are based on freely suspended loads and make noallowance for such factors as the effect of wind, suddenstopping of loads, supporting surface conditions, and operatingspeeds. Operator must reduce load ratings to take suchconditions into account. Deduction from rated capacities mustbe made for weight of hook block, weighted ball/hook, sling,spreader bar, or other suspended gear.Hook block weight is as follows:275t...........4.3ton 250t ..........3.7ton145t...........3.3ton (275t use)145t...........2.7ton (250t use)80t.............1.4ton 35t ............0.9ton 13.5t ........0.6ton
4. All capacities are rated for 360° slewing.5. Least stable rated condition is over the side.6. An 102.8ton counterweight and 18.0ton carbody weight are
required for all capacities on this chart.7. Attachment must be erected and lowered over the ends of
the crawler mounting.8. Main boom length must not exceed 91.45m.
Maximum fly jib length permitted — 36.55m.Maximum boom plus fly jib combination length permitted —70.1m+36.55m.Maximum boom length when mounting short jib is 88.40m.
9. Capacities when handling load off main boom head sheavesin case of mounting fly jib or short jib on top of boom aredetailed; if required, please consult us or nearest distributor.
10. Boom combination shall be in accordance withmanufacturer’s standard described here in “BoomCombination Diagram” of page 16.
SCX2800-2 SHORT JIB CAPACITIES:Max. 13.5ton
Note: Jib capacities is almost equal to the figures made by thededuction of apporx. 600kg from the liftcrane capacities forboom length up to 88.40m unless restricted by themaximum jib capacity shown above. As to the details,please consult us or nearest distributor.

Notes — Fly jib capacities1. Capacities included in these charts are the maximum
allowable, and are based on machine standing level on firmsupporting surface under ideal job conditions.
2. Capacities are in metric tons, and are rated in accordancewith European EN13000 Standards in terms of machinestability and structural strength limitations; the figuressurrounded by bold lines are based on factors other thanthose which would cause a tipping condition.
3.Capacities are based on freely suspended loads and make noallowance for such factors as the effect of wind, suddenstopping of loads, supporting surface conditions, and operatingspeeds. Operator must reduce load ratings to take suchconditions into account. Deduction from rated capacities mustbe made for weight of hook block, weighted ball/hook, sling,spreader bar, or other suspended gear.Hook block weight is as follows:35t.............0.9ton 13.5t .........0.6ton
4. All capacities are rated for 360° slewing.5. Least stable rated condition is over the side.6. An 102.8ton counterweight and 18.0ton carbody weight are
required for all capacities on these charts.7. Attachment must be erected and lowered over the ends of
the crawler mounting.8. Maximum fly jib length permitted — 36.55m.
Maximum boom plus fly jib combination length permitted —70.1m+36.55m.
9. Capacities when handling load off main boom head sheavesin case of mounting fly jibon top of boom are detailed; ifrequired, please consult us or nearest distributor.

Notes — Luffing jib crane capacities1. Capacities included in these charts are the maximum
allowable, and are based on machine standing level on firmsupporting surface under ideal job conditions.
2. Capacities are in metric tons, and are rated in accordancewith European EN13000 Standards in terms of machinestability and structural strength limitations; the figuressurrounded by bold lines are based on factors other thanthose which would cause a tipping condition.
3.Capacities are based on freely suspended loads and make noallowance for such factors as the effect of wind, suddenstopping of loads, supporting surface conditions, and operatingspeeds. Operator must reduce load ratings to take suchconditions into account. Deduction from rated capacities mustbe made for weight of hook block, weighted ball/hook, sling,spreader bar, or other suspended gear.Hook block weight is as follows:80t.............1.4ton 35t ............0.9ton 13.5t ........0.6ton
4. All capacities are rated for 360° swing.5. Least stable rated condition is over the side.6. An 102.8ton counterweight and 18.0ton carbody weight are
required for all capacities on these charts.7. Attachment must be erected and lowered over the ends of
the crawler mounting.8. Working radii shown above are at loading condition.9. The machine can be steplessly operated at tower angle
between 88 and 65 degrees safely; luff ing j ib cranecapacities available under any tower angle are automaticallyset up by the Load Moment Indicator, a computerizedautomatic over-load preventing system.
10. The machine shall be operated in accordance withmanufaturer's standard tower boom and jib combinationshown in page 26 here.
11. A simultaneous lift under luffing jib hook and towerboom top crane hook is not allowed.

Notes — Tower boom top crane capacities1. Capacities on these charts are available when handling
load off a 3-sheave machinery provided on 7.30m towertop section with movement of tower boom hoisting/loweringunder the condition that luffing jib offset angle to towerboom is 15 degrees.
2. Capacities included in these charts are the maximumallowable, and are based on machine standing level onfirm supporting surface under ideal job conditions.
3. Capacities are in metric tons, and are rated in accordancewith European EN13000 Standards in terms of machinestability and structural strength limitations; the figuressurrounded by bold lines are based on factors other thanthose which would cause a tipping condition.
4.Capacities are based on freely suspended loads and makeno allowance for such factors as the effect of wind, suddenstopping of loads, supporting surface conditions, andoperating speeds. Operator must reduce load ratings totake such conditions into account. Deduction from ratedcapacities must be made for weight of hook block, weightedball/hook, sling, spreader bar, or other suspended gear.Hook block weight is as follows:80t.............1.4ton 35t ............0.9ton 13.5t ........0.6ton
5. All capacities are rated for 360° swing.6. Least stable rated condition is over the side.7. An 102.8ton counterweight and 18.0ton carbody weight are
required for all capacities on this chart.8. Attachment must be erected and lowered over the ends of
the crawler mounting.9. Tower boom and jib configurations shall be in accordance
with manufacturer’s standard described here in “TowerBoom & Jib Combination Diagram” shown in page 26.
10. A simultaneous lift under luffing jib hook and towerboom top crane hook is not allowed.
