Electrification and outfitting:
Conduct power supply
Phase control guard opens the main contactor in case of phase failure
The flat cables used for festoons are PVC insulated flexible flat cables rated for 450/750V, specially designed for cranes, hoists.
clean and smooth flat cable power supply system
Cables are coded either with numbers, colours or tags for easy identification.
All hoist and crane movements are independent and can be run simultaneously.
The control panels are finished to withstand corrosion, IP55
The components are positioned in a maintenance friendly way, and the whole layout provides good protection against accidental contact.
The multi-wire type fixed cables with plastic insulation are intended for crane usage.
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.link:http://www.sinokocrane.com/p-1341/Workshop-European-Double-Girder-Overhead-Traveling-Crane.html
