Supports the hoist and trolley assembly.

2. End Trucks

Located at each end of the bridge girder.

Contain wheels that allow the crane to move along the runway beams.

May include drive motors for bridge movement (long travel).

3. Hoist Unit

The lifting mechanism, which can be:

Electric Chain Hoist (for lighter loads, up to ~5 tons).

Wire Rope Hoist (for heavier loads, up to 20+ tons).

Includes a motor, brake, gearbox, and lifting medium (chain or wire rope).

4. Trolley

The assembly that carries the hoist along the length of the bridge girder.

Can be powered (motorized) or manual (push-type, less common in remote-controlled cranes).

5. Runway System

Consists of runway beams (supported by building columns or freestanding structures).

Includes rails or tracks for the crane's end trucks to move on.

6. Remote Control System

Wireless transmitter (handheld or belt-pack style).

Receiver unit mounted on the crane (communicates via radio frequency).

Controls:

Hoist Up/Down

Trolley Traverse (Cross Travel)

Bridge Travel (Long Travel)

Emergency Stop

7. Power Supply System

Festoon System (cable and trolley for power delivery along the runway).

Conductor Bars (alternative to festooning for cleaner power transmission).

Battery-Powered (for some wireless systems).

.

8. Safety & Limit Components

Limit Switches (prevents over-travel of hoist, trolley, or bridge).

Overload Protector (prevents lifting beyond rated capacity).

Anti-Collision Sensors (if multiple cranes operate in the same area).

Emergency Stop Button (on remote and sometimes a backup on the crane).

9. Bumpers & End Stops

Rubber or hydraulic bumpers to absorb impact at runway ends.

Mechanical end stops to prevent derailment.

10. Electrical Panel / Control Box

Houses contactors, relays, and PLC (if automated).

Manages power distribution and signal processing from the remote.

Operators control the crane from a safe distance, reducing the risk of accidents from falling loads or collisions.

Better visibility of the load and surroundings, minimizing blind spots.

Emergency stop function allows immediate shutdown in hazardous situations.

2. Improved Efficiency & Productivity

Faster load handling since the operator can move freely for optimal positioning.

Reduces the need for multiple workers (no signalers required).

Smooth and precise control, especially with variable frequency drives (VFDs).

3. Operator Comfort & Ergonomics

No physical strain from pulling pendant cables or walking alongside the crane.

Wireless remote allows operation from the most convenient vantage point.

4. Cost-Effective Solution

Lower installation costs compared to double girder cranes.

Reduced labor costs (one operator can manage multiple tasks).

Minimal maintenance compared to cab-operated cranes.

5. Flexibility & Adaptability
