Double Girder Overhead Traveling Crane

European type Double Girder Overhead Traveling Crane have such design concepts as small dimension, light dead weight. Compared with traditional cranes, the limiting distance is minimum from hook to wall, and  headroom is the lowest, which makes cranes work more close to the front, and lifting height more higher that increases effective working space of workplace.

High Security

a).The safety supervises system equipped with overload limiter, and on the monitor it can display the loads value, it can remind the operator to prevent the overload.

b).Before the start, the entire controller will start self checking, includes: power voltage, default phase, the effective of each safety protective device and zero position of the button.

 

High Reliability

a).Imported motor, the insulation grade is F, and protective grade is IP54, it shall also have over heated and alarming function, the motor cover adopts aluminum alloy to drawing the molding, with better heat dissipation.

b).Germany imported reducer, harden face gear, improve the bearing ability, better sealing of the shell, ensure there no grease penetration.

c).The main electric elements adopts the international brands include Schneider, Siemens, ABB. The protective grade of the electric control box shall no less than IP 54.

d).The wheel forged by 65 Mn alloy steel, with the performance of abrasive resistance, ant fatigue and long service life.

Low-energy and Maintenance-free

a).The total power of crane reduce about 30%, energy conservation and environmental protection.

b).The multi -in-one integrated transmission mechanism has less intermediate ring knot and high transmission efficiency.

c).Adopt frequency control, high and low speed ratio 1:10, work efficiency increased by more than 20%.

d).The "Maintenance-free and easy maintenance "design concept reduces customer maintenance costs.

e).It uses advanced processing technology and high -quality imported components. Its failure rate has been greatly reduced compared to traditional GB crane, helping customers reduce operating costs.
