What’re the instructions of parts of winch?
The winch of gantry crane is the electric motor as driving force via the driving gear to make the drum rotating which with the heavy lifting capacity, rapid speed, and light and 
convenient operating and high safety and widely using. So the operator must be familiar with the winches’ parts.
The steel rope’s fixed: adding a layer on the drum, it is safer than the common steel rope’s fixed. It ‘s better to prevent the steel rope from dropping .
Drum’s transmission mode: it adopts gear axis and strap drive to drive drum which can replace the steel rope and adjust the rope’s direction.
Solenoid brake: adopting the ductile iron casting with strong ductility, firm quality, high precision and small resistance.
Specific motor: the winch adopts positive motor with the big starting torque, small inertance and long time using frequently.
Top-grade bearing: ZZHZ always adopts new top-grade bearing which famous in world with long using life, small resistance and low transmission noise.
Transmission tooth: adopting special top-grade steel products with heat treatment, firm structure.
Machine fixed mount: the top-grade is punched to be the fixed mount which is used for lifting , erecting and steel girder.
