2.2 Principles of equipment
z Lifting mechanism: Each of the two columns
has one hydraulic cylinder respectively. When
the power unit works, the hydraulic oil gets into
the lower chamber of the cylinder, forcing the
piston rod moves upward and drive the
carriage moving upward .
z
Supporting mechanism: When the vehicle
enters into the working area, adjust the
position of two-stage telescopic swing arms to
make the lifting pad near the correct lifting
point of the vehicle, and then adjust the screw
height below the pad to adapt to different
heights of vehicle chassis.
z
Balancing mechanism: To keep the balance
during the lifting and lowering process, the lift
uses two steel cables to interconnect two
carriages, forcing the carriages to rise and
descend synchronously. If the carriages and
swing arms are not on the same level, adjust
the screw at the end of the steel cable, making
the swing arms at the same level (equal
position from the floor). At this time, the steel
cables must be adjusted tightly with equal
tension, otherwise the equalization can’t be
ensured.
z
Manual safety lock system: Two safety plates
are installed on each of the column and safety
boards are welded on the back of the carriages.
When the carriages rise, safety boards will go
up and push against the safety plates .When
the carriages stop, the safety plates will get
into the slot of the safety boards to prevent the
carriages from lowering; when lowering the
carriage, lift carriages a little to disengage
safety plate and then pull the lowering handle
on power unit to lower the carriages
z Safety lock scope: The effective travel range of
safety lock mechanism is from 470mm to
1900mm,the distance between the lifting pad
and ground.
z To prevent the vehicle slip, the swing arm is
installed with positioning mechanism, making
the swing arm capable of automatic locking
during operation.
