2.2 Main structure principles:
z Lifting mechanism: Each column is installed
with a hydraulic cylinder, when hydraulic oil is
pressed from power pack into the lower
chamber of main cylinder, piston rod moves
upwards to drive the upward movement of
carriage through leaf chain.
z Load supporting mechanism
：
When vehicle
drives into the working area, adjust the angle
and telescopic length of arms to make lifting
pads at an effective load supporting position
that contact with vehicle, then adjust the lower
screw ’s height of lifting pad to make it
applicable for vehicles with different chassis.
z
Balance mechanism
：
In order to keep machine
balanced during lifting and lowering, two
carriages are interconnected and forced to
move synchronously by two wire ropes. If the
right and left carriages and arms are not at the
same level, adjust the end nut of wire rope and
pull wire ropes tight to make arms leveled.
z
Manual safety locking system: the safety
locking plates are installed on the two
carriages and the toothed bar plate is welded
on the internal wall of the column. During the
lifting of the carriage, the safety locking plate
goes up against on the toothed bar plate by
the tension of spring. When the carriage stops,
the safety locking plate opens and then is
engaged in the toothed bar slot to ensure the
carriage will not go down; when the lowering
operation is required, just raise the carriage
upward a little to loosen the safety locking
plate from the toothed bar slot, and then
manually pull the steel wire rope so as to jack
up the safety locking plate by sliding plate, so
the safety locking is released so that the
carriage can be lowered down. Because the
manual safety locking systems are installed on
the two carriages, double safety protection can
be provided; therefore, to disengage the safety
locking, the steel rope on the two carriages
shall be respectively pulled. To prevent the
vehicle slip, the swing arm is installed with
positioning mechanism, making the swing arm
capable of automatic locking during operation.
z
Safety lock scope: Safety lock mechanism is
effective when the front end of carriage is
between 450mm and 1900mm high above the
ground.
