Dear peter kirolos
Your double girder overhead crane capacity is 10ton, span is 21meter, end truck length is 3.6 to 4.0 meters, speed is 2 speed 5/20m/min. After our engineers calculation, the maximum power of the motor only needs 2*1.1kw, but your request is 2 * 3kw. This will increase costs, resulting in power waste.
In addition, the speed you request is 5/20m/min, the motor power should be 0.8/3.0kw, not 2/3kw, and this is not in line with theory.
Anyway, I give you the power 0.8/3.0kw end truck price is 4900
Rated power (Kw):0.8/3kw
Rated current (A):4.79/6.28A
Effectiveness: 52.5%/79.4%
Power factor: 0.48/0.91
Locked-rotor current/Rated current=2.5/6.5
Locked-rotor Torque/Rated Torque=1.5/1.5
Breakdown torque/Rated torque=1.8/1.8
For the previous quotation, 2*1.1kw.
It is a variable frequency motor, 5/20m/min speed through the inverter, more efficient.
