Remove obstacles around and below the platform before work. Cluttered areas and
load-bearing components can cause accidents.
4. Do not use in hazardous environments
Keep the work area well lit. Do not use or expose the device to wet or rainy locations.
The ambient temperature is lower than 10 ° C. The compressed air needs to be filtered
sufficiently effectively to prevent the pneumatic system from freezing.
5. Non-professionals should not approach
When the equipment is being lifted, no one can stand up and down, and no one can be
seated in the lifted vehicle. All visitors must maintain a safe distance within the work
-6-
area.
6. Don't force to operate the machine
Let the machine work at its designed speed. The center line of the lifted vehicle must
coincide with the center line of the platform of the lift, and deflection is strictly
prohibited. The weight of the lifted vehicle must not exceed the lifting capacity
(3200Kg) of this equipment.
7. Wear appropriate clothing
Avoid wearing loose clothing, gloves, necklaces, bracelets or jewelry that could be
caught by moving parts. It is recommended to wear non-slip shoes. Wear a hood that
wraps your long hair.
8. Do not maintain the machine under working conditions
The machine should be properly maintained regularly, such as lubrication and
adjustment. The leveling of the equipment should be carried out under no-load condition,
and the leveling operation is strictly prohibited after the load.
9. Before repairing or replacing accessories, the power of the machine must be cut off.
10. Don't let the machine run unattended. When the equipment is not working for a long
time or overnight, it should be lowered to the lowest position, drive the vehicle, and cut
off the power.
2.2 Warning sign (for illustration only)
Fig.8 Fig 9
When the lift is in operation, personnel are not allowed to approach the lift (Fig 8).
The ground near the lift should be clean and free of oil (Fig 9).
2.3 Introduction to Security Design
2.3.1 Independent dual oil circuit design
As can be seen from Figures 2 and 12, this machine uses independent dual oil circuits,
and the working solenoid valve uses a two-way check valve (Figure 3). This design can
ensure the stability, safety, and reliability of the hydraulic system, and make the
equipment operate simple debugging. At the same time, this independent dual oil circuit
design plays the role and effect of mutual protection locks.
When the lift is in a raised state, if one of the oil circuits suddenly loses pressure for
-7-
some reason, the pressure of the other oil circuit is not affected, and it can still provide
sufficient support force, similar to the role of a mechanical protection lock, to keep the
lift In the original lifting position and state, thus avoiding vehicle damage or even
personal injury.
2.3.2 Tubing explosion-proof valve
An explosion-proof valve safety part is installed at the oil inlet of the lifting
cylinder. As mentioned above, when for some special reason, the oil pipes of the two oil
circuits burst or lose pressure at the same time, the oil pressure on the outside of the
explosion-proof valve (inside of the oil cylinder) drops rapidly due to the rapid return of
the oil. The internal valve core of the explosion-proof valve closes quickly, which can
prevent the elevator from falling or slow down the speed of the elevator, and provide the
necessary escape time for the operator. So as to play an effective role in security
protection.
