3.4 POSITIONING AND INSTALLATION OF THE STRUCTURE
3.4.1 INSTALLATION OF LIFT VERSION “SI 32” WITH FLOOR PIPE CHANNEL AND “SI 32 P” WITH EMBEDDED PIPE CHANNEL
WARNING
For both versions SI 32 and SI 32 P, with floor or embedded type pipe channel, take care that the position of the pipe channel is perfectly
centered between the two columns, as indicated in (Fig. 1A)
PREPARATION OF THE PIPE CHANNEL PIT FOR VERSION SI 32 P
- If the lift must be installed with “embedded” pipe channel, version 32 P, dig a foundation trench with a section as shown in Fig.1A ,
with a length covering the total distance between the base plates of the two columns P1 and P2 as shown in Fig.1A
- When the pit is ready, cement the pipe channel to the floor as shown, bearing in mind that the channel must be positioned in the middle
of the two columns as shown in (Fig. 1A).
- Remove the packed lift protection cardboards and place the different components to the floor, so that you can work freely on the main structures.
- Remove the internal protection covers of the columns (27 Fig.2) and the covers at the bottom of the columns (28 Fig.2)
WARNING
The position of the control column P1 (2 Fig. 2) (the one that is equipped with the hydraulic unit and switchboard) has no influence on the
entry direction of the vehicle.
- Take off the packing plates (1 Fig. 6) and, keeping the columns always in horizontal position by means of supports and/or lifting systems (Fig.
6), hook first the column P1 (2 Fig. 6) (the one that is equipped with the hydraulic unit and switchboard) and the column P2 (3 Fig. 6), using
raising systems of suitable capacity (Fig. 9). Then position the columns on the pavement, in such a way that they are placed symmetrically
and aligned with each other, with the carriage of each column facing each other and respecting the distances indicated (1 Fig. 1A).
- Through the 10 holes that are along the external perimeter of the base plate of each column P1 and P2, make marks on the floor and drill the
16 mm diameter anchoring holes to fix the columns P1 and P2 to the floor; then clean the floor and the holes.
- Insert the ten M16 expansion dowels (1 Fig. 7) in each column base plate (type HILTI HSA-A M16x140, or equivalents) tapping them lightly
with an hammer.
- Place and fit on both sides of the column the triangular-shape anti-toe trapping devices (2 Fig. 7) as shown in the figure.
- Tighten the bolts of the anchor dowels (1 Fig. 7) with a torque of 100 Nm. If the dowels turn idle, replace them with larger ones.
3.4.1.2 LAYING AND CONNECTION OF THE CABLES for the lifts version SI 32 and SI 32 P:
- HYDRAULIC
- PNEUMATIC
- ELECTRIC
WARNING: Lay all pipes and cables in an orderly way, avoiding narrow bendings. Fix them together with plastic clamps.
Lay the cables on the floor or on the bottom of the embedded channel and carry out the different connections between the two columns
- Remove the protection caps of the cylinders P1 and P2 that are placed inside the columns.
- Lay down the hydraulic rubber pipe (1 Fig.12 P1) and (1 Fig.12 P2), connecting the two pipe ends to the base of each cylinder of the columns
P1 and P2, using the suitable loose fittings (2,3 Fig.12 P1) and (2,3 Fig.12 P2).
- Thread the plastic discharge pipe (1 Fig.13) and (12 Fig. 12) through the hole at the top of the column P1 (2 Fig.13) and then along the cable
conduit (4 Fig.12) that is placed inside the column P1. Stretch the pipe carefully on the floor or at the bottom of the embedded channel, then
insert the reinforcement brass sleeve (5 Fig.12) to the plastic pipe end and connect it to the preassembled cylinder connection (6 Fig.12).
Connect the other end of the discharge pipe to the hydraulic unit as shown in (5 Fig.13)
- Introduce the small diameter plastic pipe (3 Fig. 13 and 7 Fig.12) through the hole (2 Fig.13) of the column P1, pass it along the cable conduit
(4 Fig.12) that is located inside the column P1and then on the floor or at the bottom of the embedded channel. Connect the pipe by
means of the 90° fitting (8 Fig.12) to the pneumatic cylinder (9 Fig.12) that is fitted inside the column P2. Connect the other pipe end (3
Fig.13) to one of the 2 output connections (4 Fig.13) of the pneumatic electrovalve EVP.
Connect then the pneumatic solenoid valve EVP to the supply line that should deliver a maximum pressure of 8 bar.
- Pass the bipolar electric cable through the hole (3 Fig.14) of the column P1, then along (10 Fig. 12) the cable conduit (4 Fig.12) that is located
inside column P1 and finally on the floor or at the bottom of the embedded channel. Connect it to the terminal (11 Fig.12) of the electric
cable that feeds the limit switch (FC3), fitted inside the column P2. The other numbered end of the cable (1 Fig.14), must be connected
to the terminal strip (2 Fig.14) that is installed on top of the switchboard, to the two cables having the same numbers.
- Before carrying out the procedures described in the paragraphs 3.5 CONNECTION OF THE LIFT TO THE ELECTRIC SUPPLY and 3.6 FILLING
OF THE HYDRAULIC SYSTEM, read carefully and understand the chapter 4.0 concerning the control panel functions.
