5. STRUCTURAL SPECIFICATIONS

This equipment works with single-phase and three-phase motor and NGW planetary transmission, using a hook and steel wire
rope. The brake disk is unlocked electromagnetically .
Control switch: Dead man's switch.
Motor: Single-phase and three-phase motor, isolated, with high power and low inertia.
Transmission: NGW planetary gear reduction, advanced steels, providing a long life service.
Electromagnetic brake: If you lose electrical power, it is mechanically braked automatically, safe and reliable.
Steel Wire rope and Drum: The steel wire rope is installed on the drum. Fixed with safety pin ensures that the steel wire rope is
released. You can easily change the steel wire rope or adjust its direction.
5.1. GENERAL METHOD FOR CABLE SIZING
1. Power cable specification affects the lifetime and performance of the electric winch and motor. It is very important to
read the contents on the following chart carefully before use. You cannot use a power cord that is lower than those in
the chart below.
Three-phase 380V/480V
Diameter (mm)
2. Power cable must not exceed 50 meters of length, if exceeded , use a larger diameter cable to ensure proper operation.
3.
To construction applications, use power cable with low section cores, for great flexibility and improved safety.
4. Connect the power cable directly into the power supply , ensuring all connection with the respective fasteners.
5. Each line connection cable must be secured in place using bolts to prevent sparks, high temperatures, overheating, etc.
This can decrease life service of this equipment.
6. The power cable line must be fixed from one end. If the power cable comes loose the voltage would drop, which would
influence seriously on this equipment performance.
7.
To ensure the safety, the green wire must be properly grounded.
