Use chain hoists
core tip: chain hoists are lifting tool for lifting the most commonly used inside the most basic tools, generally applicable to the case of no external power relatively large lifting equipment makes the work more saves time and effort. in particular, some more precise requirements of local, general electric hoist not meet the requirements of precision, or can not install the electric hoist, the chain hoists are widely used in various aspects of lifting equipment. chain hoists are lifting gear, lifting the most commonly used inside the most basic tools, generally applicable to the case of no external power relatively large lifting equipment makes the work more saves time and effort. in particular, some areas required more precise, the average electric hoist not meet the requirements of precision, or can not install the electric hoist, the chain hoists are widely used in various aspects of the lifting equipment.
chain hoists for use:
do not overload use.
is prohibited other than with the power of human action.
in good condition before use to confirm parts, transmission parts and lifting chain lubrication good normal idling conditions.
checked before lifting the upper and lower hook is hang tight. weight suspended from the tip and other non-error operation. lifting chain should be vertically hoisted, shall have the wrong twist of the chain link, double chain hook under the aircraft can not turn.
the operator should stand on the same plane with the bracelet round of hands pull the chain, so that bracelet wheel clockwise rotation, you can make weight increase; reverse hands pull the chain, can slow down weight.
in lifting weights, strictly prohibited to do any work under the heavy weights or walking, avoid personal accident.
in the lifting process, regardless of weight up or down, pulled the chain hands, the force should be uniform gentle, not too much force, so that the chain jumps or clasp hands.
operator is found when the hand pull is greater than normal tension should immediately stop using it.
maintenance methods:
should be cleaned after use and coated with rust gourd oil, stored in a dry place.
maintenance and repair should be more familiar with the hoist body who were to prevent those who do not understand the principle of free dismantling machine performance.
hulu after cleaning, repairing, load testing should be conducted to confirm working, and reliable braking only when delivered.
brake friction surfaces must be kept clean. brake parts should be inspected regularly to prevent zhidongshiling, the phenomenon of the occurrence of material from the fall.
