Aluminium Alloy Aerial Lift Platform:

Aluminum Lifting Platform

1. Maintenance each month.
2. When the lifting platform maintenance,before the workders go into the internal,you must hang the lifting platform prevent it dive and cause casualties.

A. check roller, intermediate shaft and bearing; Oil cylinder pin shaft and bearing; Boom hinge shaft and bearing lubrication degree and wear;

B. the foregoing parts filling oil. Extend bearing life.

C. Check the hydraulic oil and oil level. Lifting table to the highest hydraulic oil level should be higher than the tank bottom and - fifty mm. Hydraulic oil color dark, sticky oil, or oil grittiness and foreign body, shall promptly replace hydraulic oil. Lifting table hydraulic system application 32 # hydraulic oil.

2. Annual maintenance

Lift the safe use of the matters needing attention

1, prevent fall safety device

Fall prevention safety device construction lifter is the important component, to rely on it to eliminate lifting cage falling accident and ensure the life safety of the crew. So far few inspection, some site even every three months testing a drop test all don't do, all think that their fall prevention safety device is no problem, but once had an accident just too late to regret. Why not according to the system routine test and inspection? Use the unit blind think not bad if good. Actually fall prevention safety device only through quality test and inspection to judge, daily operation is unable to determine whether it is good or bad, for those who fall prevention overterm service safety device, suggest or earlier inspection and regular test for good, only accomplish know fairly well, can will malignant accident nip in the bud.

2, safety switch

Elevator safety switch is designed according to the requirement of safety, the fence threshold bits, hanging cage threshold bits, forehead limit, limit switch, top and bottom limit switch, resistant to break line protection switch, etc. Some of the site in order to save trouble will be some limit switch for cancellation, and sub or damage in after repair, is equivalent to cancellation of this a few word security defense line, the accident hidden danger. Example: crane cage to loading long things, hanging in the cage can not let go to hang out, and people also cancel threshold bit or forehead limit, in the safety facilities not perfect or not in good condition, so manned objective, this kind of illegal operation is taking life joking, in order to avoid the occurrence of accident hidden danger, hoping to use the unit leadership to strengthen management, strict requirements elevator maintenance and operating personnel regularly check the safety and reliability of the various safety switch, prevent the happening of the accident.
