Electric hoist chain maintenance:

First of all, chain electric hoist gear box oil from the working up to 500 hours please check the oil quantity is enough, after third months of regular inspection lubricant, deficiencies need to refuel.
Second, the use of 15 ton electric chain hoist in outdoor, should get the rainproof equipment.
Third, often keep electric chain hoist parts dry, after operation, please leave China gourd high-temperature zone humid area, or chemical District, in order to maintain its performance.
Fourth,2.2m/min electric chain hoist maintenance, chain please oil lubrication, high dust factory please on oil, and periodically remove the chain and guide foreign body in the limit groove group, to ensure the smooth operation of the chain.
Fifth, 380v electric chain hoists long-term when not in use, should be treated against rust and cleaning and maintenance, and run up and down the 1-3 minutes to maintain its performance.

a. When lifting heavy objects in each class for the first time (or the maximum load weight), should be lifting height of 0.5 meters from the ground after the heavy down again, check the brake performance, reliable after confirmation, then normal operation.
b. Operator in the job, should be required for the following operations to ring the alarm.
① lifting, landing weight; great start when the car driving. 1.5 ton electric chain hoists
② clear sight of the crane when traveling through to continuous-ringing alarm;
③ traveling crane when the crane near the cross in another.
④ lifting heavy objects near the staff.
c. Operation running under a unified command signal should be. 15 ton electric chain hoist
d. Work in a power outage, the controller should handle all placed in the "zero" position, re-work should be checked before the crane movements are normal.
e. Large cranes, trolley during normal operation, parking brake open anti prohibited; transform large trolley direction of movement, the handle

Electric Stacker often use should pay attention to maintenance , especially for electric cars piled high maintenance system to do better , then how do electric stacker hydraulic system maintenance job?
 select the appropriate hydraulic oil:
Hydraulic oil in the hydraulic system of electric forklift trucks passing plays pressure , lubrication , cooling and sealing effect, the inappropriate choice of hydraulic oil hydraulic system failure and durability of the early decline. When grade hydraulic oil should 15 ton electric chain hoist randomly select "Manual" specified in special circumstances need to use on behalf of the oil, it should seek the same performance as the original grade performance. Different brands of hydraulic oil can not be mixed , to prevent hydraulic oil to produce a chemical reaction  the performance changes. Dark brown , white , smelly oil hydraulic oil is bad you can not use .2, to prevent air from entering the hydraulic system mini electric hoist Containing hydraulic fluid under pressure in the temperature volume ratio of 6 to 8% of the air pressure is reduced when the air is free from the oil , the hydraulic components bubble burst " cavitation " noise. A lot of air into the oil will cause " cavitation " phenomenon intensified, hydraulic oil compressibility increases, job insecurity, reduced efficiency , implementation of components appear to work "crawling " and other adverse consequences. In addition , the air also makes hydraulic oil oxidation, accelerated deterioration of the oil.
