High safety and reliability
- This machine is equipped with a load-limiting protection device to avoid the adverse consequences caused by overload.
- The machine is equipped with upper and lower limit devices. When the hook is raised or lowered to the limit position, the machine automatically cuts off the power and the hook stops.
- This unit is equipped with an emergency stop button to enable the operator to immediately turn off the power in case of a crisis.
- The lifting hook is provided with a locking device to prevent the lock from accidentally slipping.
- The motor is equipped with a thermal protection device. When the motor is overheated due to frequent use, the device will automatically cut off the motor to protect the motor from being burned out.
High component strength
- The upper and lower hooks are made of high-strength alloy steel. After intensified heat treatment, they have high toughness. Even if the body is damaged by overload, the hook will only produce sag deformation without brittle fracture.
- The main parts of the machine are made of high-grade alloy steel material and processed by many special heat treatment processes. It has the characteristics of high strength and good wear resistance.
Novel structure
- This machine adopts two-stage gear transmission, and the high-speed stage is helical gear transmission, so the transmission is stable and the noise is small.
- This machine adopts high-strength aluminum alloy body, which is beautiful in appearance, compact in machine position, small in size and light in weight.
