Features

• All drums are grooved to facilitate the regular winding of steel cables onto the drum.
• All motors are squirrel-cage induction motors manufactured by a top-tier domestic factory, featuring high starting torque, low starting current, and resistance to high temperatures.
• All steel cables are made of 6×Sec(37)+FC, with a safety factor greater than 5, making them particularly suitable for well drilling, cranes, hoists, and heavy construction machinery.
• Adjustable safety brake – the brakes activate immediately in the event of a power outage, ensuring safety.
• The braking torque of an electromagnetic brake is more than 1.5 times the maximum torque required to suspend the rated load.
• The helical gears made of SNCM220 material undergo carburizing heat treatment, achieving a hardness of over 60HRC, while the S45C gear material undergoes high-frequency heat treatment, achieving a hardness of over 50HRC.

Option

• Dual-speed control – Dual-motor mechanical systems can achieve a speed ratio of 10:1 or 6:1, and can also use frequency converter control to achieve stepless speed control to position load requirements.
• Remote control switch – Enables remote control.
• Cooling forced fan – A forced fan is installed on the brake side of the motor, which is suitable for high-temperature environments or frequent lifting and lowering of cranes, and can extend the life of the motor and brake.
• 360-degree rotating lower hook – The breaking load is more than five times the rated service load.
