DJB series variable frequency electric winch is a new generation of special lifting tool for 7000 automatic drilling rig,it was designed by our company and we have completely independent intellectual property rights and obtained the invention patent.
The the control system of electric winch is VFD control system,and the power is explosion-proof AC variable Frequency Brake Motor,drive the drum by planetary gear reduction mechanism,to wrap or loosen wire rope to realize lifting / decentralization object.The electric winch has advanced technology, reliable performance, low energy consumption, high efficiency, safe and reliable, high automation, simple structure and stable transmission.Since its application, it has been widely affirmed and praised by users.
Technical characteristics

Energy saving and consumption reduction.Compared with air winch, electric winch saves more than 2300% energy.

Speed up, load up, improve effect.Compared with pneumatic winch, the speed is increased by more than 10% when empty load, the speed is increased more than 50% at full load, the load capacity is increased by more than 20% at low speed, and the load capacity is increased by more than 4 times at high speed.

Three types of brakes to ensure safety.The winch is equipped with motor energy consumption brake、motor disc brake、belt brake.multiple brakes to ensure safety.

Automatic brake, automatic rope arrangement.The winch controlled by frequency converter，it’s Motor energy consumption braking and disc brake automatic cutting in when running.

wide adaptability.The protection levels of various electrical equipment is above IP55, which can meet the requirements of desert, ocean, polar and other areas.

Can be operated remotely and is convenient to operate.The winch is equipped with two sets of control systems: the local control box( emergency operation ) and the handheld control box is a mobile control box, which can be moved when working in the invisible area, such as wellhead under the floor,very convenient.

The structure is simple and the maintenance is convenient.The motor, planet reducer and in a line, simple structure and convenient maintenance.

The transmission is stable and the speed is accurate.The winch is driven by frequency converter, non-polar speed regulation, stable transmission, accurate speed, no noise and high efficiency.
