End girder is matched with rail buffer and rail clearance device, anti-friction bearings

Full-length service platform along the crane bridge is supplied,where it si equippe with protective hand railing and toe strips.

Compacted gearmotor driving, stepless control, hardern gear, safety disck brake

High proection class IP54, F class, 40% ED

Electrification and outfitting

slide wire or C shape slide line conductor power supply.

all hoist and crane movements are independent and an be run at same time.

The control panels are finished to withstand corrosion, IP54

The components are positioned in a maintenance friendly way, and the whole layout provides good protection against accidental contact.

Cables are coded either with numbers, colours or tags for easy identification

The flate cables used for festoons are PVC insulated flexible flat cables rated for 450/750V, specially designed for cranes, hoists.

Festoon cables are suspended on cable saddles, fixed to cable trolleys, running in a galvanised C-track, which is connected to the main girder with bolted or welded support brackets.

Lifting units

high tensile steel wire rope. Din standard hook

Safety features

1. Overload protection: If the material is over the capacity, the crane will give a sharp warning for protection itself.

2. Emergency brake: If the operation staff encounters some emergency situation, we could start the emergency brake system to protection the related treasure.

3. Control Method: Room control or remote control to avoid any injure to the operation staff

4. Main lifting motor: with thermal protection and currency protection.

5. Hooks with latch

6. Rubber buffers

7. Protective earthing

8. Crane switch and travel end switch

9. Sub-assemblies characteristic are tested before assembly.
