coated to observe whether lubricating grease is filled to guide surface of column and sliding
block. If there is no lubricating grease, proper amount of lubricating grease can be filled.
Meanwhile, lubricating grease or oil shall be applied to wheel and axle of upper and lower
steel wire rope to reduce wear and prolong service life.
12. Load test: lubricating grease shall be applied to each lubricating point and surface. In
addition, the inspection on whether oil leakage phenomenon exists in oil-way or whether the
foot margin assembly is fasten. After the above is normal, the test can be carried out. The
method of load test is identical to no-load test. The load-test ends where there is no noise
and leakage and the hoist time and height is compliant with technical parameters after 2~3
times loading is performed.
13. After load commissioning, the length of steel wire rope will be slightly extended. Thus, the
leveling shall be carried out once again. The machine can be put into use after step 4 is
repeated.
Chapter VI Safety Mechanism
Safety mechanism of two post series lifts
Note: upon the use of two post series lift, especially lifting vehicle, our lifter will
generate the sound indicating that safety mechanism is locked in its safety. If user hears such
sound, it shows that our safety mechanism operates normally. In this case, the lifter can be
used in a safe way. If the safety does not generate the sound indicating that safety
mechanism is locked, it is not allowed to use machine. In this case, we shall open safety
adjusting window, screw down cross screw in safety mechanism till such sound is generated.
After the mechanical hoisting, we shall press down manual unloading valve to make safety
