Installation/Operation & Maintenance Manual
HFL4140E 4-POST ALIGNMENT LIFT
Chapter 1 DESCRIPTION OF THE
MACHINE
Four-post lifts are fixed installations, i.e. anchored to
the floor; the units are designed and built for lifting
cars and vans and holding them in an elevated
position.
The units are essentially made up of a fixed part that
is anchored to the floor (posts) and a moving part
(cross-pieces and platforms). The operation is
electro-hydraulic.
■There are four basic parts of the lifts:
■Fixed structure assembly;
■Movable structure assembly;
■Lifting assembly;
■Safety devices.
Fig. 1 shows the various parts of the lift and the
operating zones in the surrounding area.
Fig. 1
The lift is composed of the following main parts:
Control side post (conventionally the front right-hand
post) (Fig. 1-1)
■Front left post (Fig. 1-2)
■Rear left post (Fig. 1-3)
■Rear right post (Fig. 1-4)
■Control side cross-piece (front cross-piece)
(Fig. 1-5)
■Rear cross-piece (Fig. 1-6)
■Right fixed platform (Fig. 1-7)
■Left moving platform (Fig. 1-8)
Operator side: this is the front of the lift, including
the area reserved for the operator with the control
panel. The operator side is opposite the vehicle
access side.
Rear side: it is the side opposed the operator’s one,
with the lift access ramps.
Right and left sides: the right and left is considered
from the operator’s standpoint when facing the lift.
Danger zone: an area that must be kept clear of
persons when the lift is in use; refer to Chapter
“Safety devices” for details.
1.1 FIXED STRUCTURE ASSEMBLY
The structure includes the four vertical posts in bent
steel plate with a pre-drilled base plate for
expansion anchors to secure the unit to the floor
(see Chapter 4 “Installation”).
Each post houses:
■A safety rod with slots (Fig.2-2) to engage the
safety wedges;
■A steel cable for lifting (Fig. 2-1);
■A guide for the cross-piece vertical sliding (Fig.
2-3).
Fig. 2
The following parts are anchored to the top of each
post:
■End of safety rod (Fig. 3-2), (secured with M20
nut and lock nut, class 8.8);
■The end of the steel cable (Fig. 3-1), which is
fitted with an M20 threaded shank (fixed with
M20 nut and lock nut, class 6S).
The length of the cables can be perfectly adjusted,
also to take up slack due to stretching, thanks to the
length of the threaded shanks on the ends of the
cables.
