Main Components:

electric motor	Gearbox	Brake
low-vibration, quiet running Thermal contacts to protect against overheating Designed for extended operation periods, classified in accordance with FEM IP 54 enclosure the motor brand is customized	Three stage, helical gear reducer Low running noise Lubrication for life the brand is customized	DC disc brake with brake release monitoring (optional) Minimum safety factor of 1.8 Rapid response through integrated brake modul
slide wire	crane cable	steel wire rope
safe and reliable, low electric shock hazard energy conservation, low loss long service life easy for installation and maintenance	insulated conductor high waterproof grade high safety factor	wear-resisting, corrosion resistance high tensile strength good flexibility
wheel	couplings	steel drum
Manufactured from fine gain, fully killed, vacuum degassed forged medium carbon steel Provide an additional 40% load carrying capability over rim toughened wheels	Compensation for axial, radial and angular misalignment Convenient axial plugging assembly No brittlement at low temperature Good slippery and frictional properties Resistance to chemical corrosion	Generously dimensioned drum for long rope service life Reliable operation even in critical environments It encircles the drum completely so that the rope may not uncoil even when the hoist is in unload condition
