10 Ton Single Overhead Bridge Crane

A Wireless Remote Control Overhead Bridge Crane is made up of several critical components that work together to lift, move, and lower heavy materials with precision and safety. Below is an overview of the main components and their functions:

1. Main Girder (Bridge Beam)

The primary load-bearing structure of the crane

Usually fabricated as a box girder or I-beam

Supports the hoist and trolley

Designed for strength, stiffness, and minimal deflection

2. End Carriages (End Trucks)

Located at both ends of the girder

Equipped with travel wheels

Allow the crane to move along runway rails

Driven by geared motors for smooth travel

 

3. Electric Hoist

The core lifting unit

Typically includes:

Motor

Gearbox

Drum & wire rope

Hook block

👉 Common types:

CD/MD wire rope hoist (standard)

European low-headroom hoist (compact & efficient)

4. Trolley (Cross Travel Mechanism)

Carries the hoist

Moves horizontally along the girder

Enables left–right positioning of the load

 

5. Crane Travel Mechanism (Long Travel)

Drives the entire crane along the runway

Includes:

Motors

Gear reducers

Wheels

👉 Provides forward/backward movement

 

6. Hook Block

The load handling device

Includes:

Hook

Pulley system (sheaves)

Designed with safety latch to prevent load slipping

7. Electrical System and Power Supply

Function: The crane requires electrical power to operate the motors, control systems, and remote.

Components:

Power Supply: The crane typically operates on 380V, 415V, or 480V industrial power for larger systems.

Circuit Breakers: Safety devices to protect the crane from power surges or electrical faults.

Cables: Heavy-duty cables deliver power from the source to the crane's various components.

8. Electrical System

Powers and controls the crane

Includes:

Control panel

Wiring & cables

Festoon system or conductor bars

👉 Ensures safe and reliable operation

---

9. Control System

Interface used by operator

Common types:

Pendant control (wired)

Wireless remote control

Cabin control (rare for single girder)

---

10. Runway System

Rails on which the crane travels

Supported by building structure or columns

Includes:

Rail tracks

Rail clamps & buffers

 

11. Safety Features

Emergency Stop System: A manual emergency stop button on the remote control and control panel to immediately halt all crane operations.

Anti-Sway System: Some cranes are equipped with an anti-sway system to minimize swinging of the load during movement.

Obstacle Detection: Sensors detect nearby obstacles, ensuring safe operation and preventing collisions.

12. Structural Components (Frame, Girders, etc.)

Function: These parts provide the rigidity and strength needed to carry heavy loads.

Types:

Single Girder: Lighter-duty cranes.

Double Girder: Heavy-duty cranes capable of lifting larger loads.

Materials: Typically made of high-strength steel to ensure durability under heavy load conditions.
