● To ensure the wire rope tied on the drum groove correctly and not overlapping with each wire, it takes longer operation life. 

● Design for more convenient and easy to disassembl. 

● Not only meets the demand of different special reduction request but also reduces noise, provides high efficiency and customized services. 

● Installed directly, so almost no wheelers in the external rotation. It's better to ensure the safety of machine operators. Easy to maintain and disassemble. 

● To use single point fixed the torque arm device which is avoided the gear box rotated by the torque. This device is also buffering effect and extending the operation life of gearbox. 

● At the same time the brake has excellent buffering capabilities to achieve the double anti-dropped protection.

● Designed specifically for large-tonnage, double hook, strong and durable. 

● The Pulley is made by gray casting iron and 18 times big of steel wire rope.The hook is made by alloy steel with heat treatment. It can be rotated for 360 degrees and over 4 times of safety ranking loading.The security protection film remains attached to the safe operation. 

● Using famous brand of high volume electromagnetic switch which is designed by inching standard. It could be continuously used and high duty cycle. 

● Electromagnetic switch attaches the mechanical linkage, coil is installed surge protector, safety and stable. 

● Control voltage standard is 220V (Option 110; 48; 24 V). 

● Inverter is available.

● Frequency conversion type of motor which special purpose for hoist (Heavy industrial could select wound type motor). It provides buffering effect and speed changed function. Using gray cast iron for motor. Insulation ranking F class. Temperature reached 155 ℃ (option H class, temperature reached 180℃). While the temperature is overheating, the overheating protection device will be started and stop operation to avoid motor burning out. 

● High performance 250% starting torque, big horsepowe, high duty cycle and silent operation. 

● Conforming with duty cycle 30%ED standard. (On / Off frequency 180 times/hour) Option 60%ED is available. 

● The hydraulic and electromagnetic drum brake system which special purpose for big tonnage hoist. Brake torque reached 150% which action indeed, strong braking force. It brakes when power cut off. High security and easy adjusted. 

● Fan can be installed to cool down the temperature.

● While over loading, it cuts off the power automatically which avoids hoist and steel wire rope overloading and safety issue. Meanwhile, it can extend service life of the hoist . 

● Mechanical mode (connect with reel) and digital mode (on the steel wire rope) are optional .
