H.09 Operation and maintenance for lifting winch
H.09.1 Purpose and characters
Lifting winch is used for fixing goods, therefore it is an absolutely necessary part for
loader crane, is one of the most important basic organizations of the loader crane.
Lifting winch adopt the NGW planet gear in the design, has characteristics of high
efficient , small volume , light weight , low voice, compact structure , steady running,big scope
transfer power etc.
Brake friction slice: wet type friction slice to be placed inside the brake shell, the brake
shell is installed on the front of organization , is convenient for replacement of friction slice.
H.09.2 Reasonable use and greasing
Do not use lifting winch to lift person!
Do not put the lifting winch in the place containing acid or alkaline etc corroded gas, make

temperature is: -20ºC～+40ºC.
Using abrasion-resistant hydraulic oil, replace hydraulic oil at the regular intervals, replace
the oil within 30 days after the organization is delivered, thereafter replace it every 3～6
months .
Lubricant oil:
H.09.3 Safekeeping

lifting winch, and leave it full of oil with lower acidic value， When storage,
place without odour of decaying ; To avoid quickening the ageing process, do not store it for
long in the place where the temperature is too high or the temperature is under -20ºC，drain out
the lower acidic value oil and add proper brand of oil when again using the machine.
