Chapter 2 Description of machine
2.1 USAGE
This two post lift can lift various vehicles which weight is less than 4000kg. And it is
suitable for vehicle test, repair, maintenance and care.
This lift is designed to lift vehicles, not for other usage.
Forbid to use for washing and spraying vehicles!
Forbid to lift vehicle which weight is over 4000KG!
2.2 FEATURES
Design and manufacture according to relevant standard, and machine performs stable and reliable.
With hydraulic locking and mechanical locking system, safety and reliable.
With insurance bar for top protection, to prevent effectively the vehicle from being damaged.
With safety valve and antiknock valve in case of hydraulic failure or over loading, to prevent the lift from
lowering quickly when oil pipe bursts.
Double cylinder drive, to lift and lower stably.
Adopt imported hydraulic and electrical components from Italy, Germany and Japan.
2.3 MAIN FABRIC PRINCIPLE:
Lifting fabric: Each post has one cylinder, when pump the oil into the cylinder, the cylinder pole will move
upwards, to hold the carriage move upwards.
Support fabric: After driving the vehicle into the working area, adjust the angle of arms and length of extension
arms, to ensure the arms support on the effective vehicle bearing point.
Fix the position of vehicle by arm orientation fabric, in case of slipping.
Then adjust the screw to fit different height chassis.
Balance fabric: To keep the balance during lifting, connect the two carriages with two steel cables to ensure the
synchronization of the two. Then tighten the steel cable, or it will not synchronize.
If carriages, arms are not in level, adjust the steel cable nut, to ensure the carriages and arms in level. Then
tighten the cables to ensure the synchronization.
Electromagnetic safety locking fabric: During lifting, each post has safety locking device to ensure the lift can
stop reliable without falling.
Principal of electromagnetic safety locking: The upper side of safety racks adhibit on the safety teeth for the
angle and deadweight. The carriages push the safety rack and go up step by step. If failure of lift and begins to
lower quickly, safety rack will clip on the teeth to stop the carriage to stop lowering. (See picture 9 and 10)
There are orientation device on the arms, to lock arms when they are in proper position, which can prevent the
vehicle from slipping.

Thickness of concrete ≥ 200mm，to ensure the intensity reach to 3000PSI（2.1Kg/mm
2
）upwards。
Height of indoor should be over 4000 mm，regard to hold enough space for all lifting vehicles(approximate 4m
from the lift center)
Distance from post to wall should be at lease 1200mm. In case of emergency situation or working convenience,
should consider about enough space for safety channel.
3.2.2 FLOOR LAYOUT
It’s very important for the floor layout (picture 3). If it’s not correct, there may be some
problems during installation and operation. The total level error is less than 4mm, which
can decrease the problems during final installation.
