2 Installazione

Use the appropriate personal safety items (gloves, helmet, accident-proof shoes, and harness)

Always ensure the working tools and any other object against accidental downfall.

The sequence of installation operations of the car frames AHT6, AHT8 and AHT6 CTR are identical, unless otherwise specified. All pictures of this handbook show the type AHT6 or, where otherwise specified the type AHT6 CTR 650.

The maximum attention should be paid to the following points:

During assembly of the various components or when the installation is completed payattention to possible cutting trimmings (machining residual).

Before beginning installation it shall be necessary to remove from the lift shaft any deposits andrubbles resulting from the building works.

The car frame installation is carried out in the area of the lift shaft bottom.

Only the delivered pins and bolts may be used. The screws belong to the class 8,8 the bolts tothe class 6G.

The opening of the small bags containing the delivered screws and bolts has to follow the same se-quence of the operations explained in present handbook.

Respect the tightening torques prescribed for the threaded couplings.

All screws used for the assembly of our products are screwed by means of a tighteningtorque as shown on following table:

SCREW MAX TORQUE [Nm] MIN TORQUE [Nm]M4 2.6 2.1M5 5.1 4.1M6 9 7M8 21 17M10 42 34M12 71.4 57.1M14 114 91

In case of need please refer to above table.

2.1 Pit bottom- Take the dimensions of the shaft, height of the pit,

the run, length of the header and the plumbing of the walls, and compare these measurements with those given on the technical drawing of the instal-ment.

- In the event that the measurements do not match, suspend installation and take appropriate measu-

res.

2.1.1 Positioning template for the start guide points

a) Mount the two positioning brackets (1) inside the template (2) as illustrated in Fig.1, to fix - lower the tab using a tool (3).

b) Check that the quota “D” (Figg.2 and 4) correspon-ds to the value of the distance between guides DTG (±1 mm.) and that the two positioning brackets (1) are centred on the template (2) that means that the two quotas “F” and “G” are exactly matching.

c) Position the template on the bottom of the pit respecting quotas A,B, and C which can be found on the instalment project drawing (Fig. 4). The 4 holes “S” are perfectly symmetrical, therefore in this phase the direction of the positioning of the template on the pit is not important at all.

2.1.2 Positioning of guidesPut on individual protection gear, in particular for accidental falls.

a) After positioning the guide fixing brackets along the shaft according to the indications in the in-stalment plans, place the two start guides on the template for the start guides. The choice of the type of guide (section or whole guide) and the type of connection (male or female) to rest on the bottom of the template must be made according to the indications in the instalment plans.The guides must be positioned slotting the “mu-shroom head” into the appropriate groove of the positioning bracket (1) and maintaining it aligned on the bottom of the groove itself (Fig. 5), whilst respecting quota C in Fig. 4.

b) After checking the alignment of the two start gui-des, fix both to the template using the two angles (4), the nuts and bolts of set F300.23.0024 to fix the angles to the template and the clamps of the “clamp set” to fasten the guides with the angles (Fig. 6).

2.1.3 Assembling dead-end hitch

2.1.3.1 Assembly of fix head for AHT6-8 and AHT6 CTR

Proceed as described below, using nuts and bolts of set F300.23.0024:

a) Position the dead-end hitch (5) inside the guide start template. Since the template is symmetrical, correctly mount the dead-end hitch making as follows:

a1) in case of plants with AHT6-8 with standard roping (sx), that is left version (Fig. 4a), posi-tion the front part of the dead-end switch (Fig. 8a) in correspondence of the mark “V” on the right.

a2) in case of plants with AHT6-8 with reverse ro-ping (dx), that is right version (Fig. 4b), position the front part of the dead-end switch (Fit. 8b) in correspondence of the mark “V” on the left.

a3) in case of AHT6 CTR the convention of the standard or reverse roping is the same as for the AHT6-8. Position the dead-end hitch perfectly in the center of the template with its front part facing the opposite side of the traction ropes on the car frame.

a4) in case of AHT6 CTR with symmetrical load bar (sd) (Fig. 4c) the dead-end hitch must be posi-tioned perfectly in the centre of the template (Fig.8c).

b) Fix the dead-end hitch to the template by means of the two screws M10x30 (Fig. 7). The two screws must be inserted in correspondence with the two vertical slots which are located exactly on the two holes existing on the back side of the dead-end switch.

c) Take the four rope tension rods (6) pre-assembled without spring and remove the split pin and the two nuts.

Do not disassemble the rope tension rods with pre-assembled spring: they will serve later to fix the traction ropes to the car frame load bar.

d) insert the 4 tension rods into the holes of the de-ad-end hitch.

2.1.4 Assembly of the polyuretyanic buffer support in pit.

The car frames type AHT6-8 and AHT6 CTR in stan-dard version require one single polyurethanic buffer which is installed on the dedicated support which is positioned on the axis of the piston support. The buffer support, if not otherwise requested, is supplied with a standard length of 1100 mm which has to be adjusted according to needs by cutting its lower part. In order to assemble the support follow these steps:

a) With a help of the project drawing calculate the definitive support’s length. Mind the fact that in normal conditions the buffer is 80 mm high while when completely pressed its just 8 mm high (the difference of 72 mm). If necessary proceed with cutting until the proper length indicated on the drawing has been reached;

b) Fix the base (10) to the pit template by loosening the screw of the dead-end hitch, sliding in the base (10) and tightening up the screw (Fig. 15);

c) Insert the support (11) onto the base and fix two brackets (12) with the screws from the package F300.23.0043. Make sure that the support is secu-rely fastened to the piston support (9) (Fig. 16);

d) Mount the buffer (13) on the top of the support (11) with the screws from the package F300.23.0043. For the pits deeper than 1500 mm, the support (11) is made of a 60x60 mm tube cut to the re-quired length, which is assembled in a way similar to the one described in points b) and c). The only difference is mounting of the of the buffer which has to be fixed to the positioning platelet (14) with the screws from the package F300.23.0043 and then inserted onto the 60x60 tube (Fig. 17);

e) The assembled buffer is represented in Fig. 41 on page 27.
