Technical description
The KOALA LP is designed and manufactured for lifting vehicles by means of its towing arm in order to
allow for the repair of the vehicle’s body work.
Its structure provides for the rapid lifting of the vehicle and is ideal for flanking more complete equipment:
jig lifts.
Physically, the LP is made up of a lower structure, comprised of the base to be fastened to the ground (2,
fig. 3.1), an upper structure (1, fig. 3.1.) and two lifting rods (3, fig. 3.1), connected in a scissor-like fashion,
which connect the upper frame to the lower frame.
The lifting movement is powered by two hydraulic cylinders (4, fig. 3.1), which are controlled by a special
electro-hydraulic control unit located inside a structure that also contains the electrical panel and the
pneumatic solenoid valve (9, fig. 3.1). The hydraulic control unit is comprised of a motor that controls a
hydraulic pump. The oil is located in the appropriate tank.
The control unit also contains a pneumatic safety release solenoid valve.
The safety catch device intervenes in the event of a hydraulic system malfunction, by mechanically
stopping the lift’s descent.
When stopping at various heights for work operations, the safety catch device will slide into one of the
notches on the base, illustrated in fig. 3.2. The user can press an appropriate button to activate, by means
of a solenoid valve, the cylinder that raises the safety catch device (thereby disengaging the safety
system). Upon releasing the button, the safety device will automatically be re-activated.
