The cabin

The winch manufactured by ZOLLERN in accordance with European standards CEN TC 151.
Equipped with internal planetary reducer,the winch with the modular sturture has a small size and easy installating.
The braking of the hoist is made by the hydraulic self-locking brakes makes the whole design compact,low-wear and without maintenance.
Main winch has a function of winding or releasing of no-load at a high speed,and raising at micro speed or lowering at slow speed.
The main and the auxiliary lifting devices are drived separately by twosets of individual deceleration machine and motor.

Advanced doisting system

The hydraulic system with the advanced variable constant power system has a wide speed range, high-speed,micro-speed to meet the demands of the installating purpose cranes.

The advanced hydraulic system

ZOLLERN hoisting deceleration machine.
ZOLLERN amplitude deceleration machine.
with advanced Germany technique,excellent reliability and quality.

Deceleration machine

Maneuverting unit with diesel from shanghai.
Excellent,powerful dynamic performance.
Low speed and high torque,saving energy and lower fuel consumption,high reliable.

Engine

The power take-off systerm with the electronic moment limiter transmit the Signal for the tension force of the steel rope to the computer,limiting and Alarming to prevent from lifting overload,preventing from any damages or safety accidents.

The power Takeoff System

With the advanced electronic limit device,the jibs are limited and alarmed automatically to prevent being over inclining,resulting in any damages of the machine.

Approaching Switch

The angle sensor transmit the signals for the angle of the jib safely and Accurately to the computerized device,to ensure the jib is being well Controlled and working smoothly.

The angle sensor

With the observation of working conditions of the machine Directly,immediately and multi-directionally displayed on the Screen,theoperators can easily handle any problems appeared during operation.

The computer

We imported the device from the ZOLERN GmbH&Co,KG in Germany which has a function of limiting to hook overwinding and alarming automatically,preventing from the damage of overwinding,reducing greatly the possibility of damage to the machine.
