The system consists of the adjustable pull arm equipped
with on-board control pump, the clamps for securing the
vehicle and the pull chain.
The adjustable pull arm (Figure 4) consists basically
of a upright (2) hinged to the horizontal body and can be
rotated in the plane.
The upright is tensioned by a single-acting hydraulic jack
(12 - fi g. 4).
The horizontal body of the pull arm consists of a base (1)
that allows it to rotate in the horizontal plane.
The pull arm is fastened to the lift by means of the block (4)
welded to the adjustment plate (3) which fi ts into a special
support cut into the structure of the lift's upper movable
platform.
This plate has a series of holes permitting horizontal
adjustment of the pull arm; the latter is kept in a safe
position by a stop pin (8), which can be remote-controlled
by a mechanism (5) with a control lever (9).
When the pull arm is not fi tted on the lift, it can be easily
pushmanoeuvred by an operator via the 4 castors (6).
The jack controlling the pull arm is driven by an independent
pneumo-hydraulic pump (10) with control.
The pneumo-hydraulic pump can be fed by the
compressed air in the workshop distribution system or by
a portable compressor via the fl exible pipe (16).The body
of the vehicle to be put under traction must be secured by
means of a suitably strong chain (13 - fi g. 4) connected to
the pulley (14) which can be height-adjusted and locked in
position by means of the pin (15).
The special clamps are mounted at the ends of the
supports (4 - fi g.2) fastened to the lift's mobile upper
platform.
These clamps permit the safe clamping of the underbody
of the damaged vehicle for the subsequent tensioning of
the part of the vehicle to be repaired.
