2.2 Main structure principles:
 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.
 Load supporting mechanism ： When vehicle
drives into the working area, adjust the angle
and telescopic length of arms to make lifting
pads at the 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.
 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.
 Electromagnet safety lock mechanism: Each
column is installed with two safety lock devices,
when they start to work, this dual safety
mechanism can make the machine stop reliably
without falling during lifting process.
 Principles of electromagnet safety lock
mechanism ： The upper end of safety plate
always attaches to the safety orifice closely.
When the carriage rises, the safety orifice
utilizes its inclined angle to push away the safety
plate and rises progressively. In case of failure
during the moving of the carriage, the rapid
falling will occur, then the safety plate will block
into the safety orifice, preventing the falling of
the carriage (Fig. 3). When the electromagnet is
actuated, the safety plate is released for
carriage lowering (Fig.2e 、 2f)
 To prevent the vehicle slip, the swing arm is
installed with positioning mechanism, making
the swing arm capable of automatic locking
during operation.
 Safety lock scope: Safety lock mechanism works
when the front end of carriage is between
450mm and 1900mm high above the ground.
