50 Ton EOT Double Girder Overhead Crane Heavy Lifting Equipment With Electric Hoist

50 Ton EOT Double Girder Overhead Crane Heavy Lifting Equipment With Electric Hoist


General description

LH model electric hoist overhead crane has such features as tight dimensions, low building headroom, light dead weight and light wheel load. LH / QD double girder overhead crane is a heavy lift equipment for general industry application. These type is more durable and reliable than single girder overhead crane. Duty class of LH double girder overhead crane is A3~A5 while this type can fit the low headroom very well. QD type is more heavy type.


LH type double girder overhead crane is design for low headroom where single girder overhead crane can not fit the space. Unique trolley structure design make the crane saving more space for working. Lift capacity available 3 ton to 32 ton and we could provide max. up to 50 ton, Span up to 31.5m, lift height we could provide as customers' request.

Detail features

1. Double girder structure makes the crane bridge have sufficient strength, rigidity, and stability.

2. Rail-in-middle box girder design thoroughly meets the requirement to strength, rigidity and stability.

3. End beams designed with simple structure can be easily installed with main beam by high-strength bolts.

4. CD or MD high quality wire rope electric hoist is used as lifting mechanism.

5. Soft starting motors with light current is used with ground control.

6. Dual-motor independent drive device is adopted to reduce the wear of rail gnawing and reduce the possibility of wheel climb off track fault, etc.

7. Motor is directly controlled by contactor, which can make the motor achieve single and double speed and reversing control.

8. Frequency converter is used to change the frequency and voltage of motor power to realize the function of speed adjustment control of motor.

9. Multiple safety protection system is adopted, including short circuit protection, no-voltage protection, emergency power off switch protection, overload limit protection, travel limit protection, zero and chain protection, ground protection, etc.
