A single girder 5-ton overhead crane consists of several key components that work together to lift, move, and position heavy loads efficiently. Here are the main components:

1. Bridge Girder (Main Beam)
The primary horizontal beam that spans the width of the workspace.

Typically made of rolled steel or welded box sections for strength.

Supports the hoist and trolley.

 

 

2. End Trucks (End Carriages)
Located at both ends of the bridge girder.

Equipped with wheels that run on the runway rails.

Houses the drive mechanism for bridge movement (longitudinal travel).

 

3. Hoist Unit
The lifting mechanism (electric or manual) that raises and lowers the load.

Common types include electric chain hoists or wire rope hoists (for 5-ton capacity).

Mounted on a trolley for horizontal movement.

4. Trolley
A wheeled unit that carries the hoist along the length of the girder (cross travel).

Can be powered (motorized) or manual, depending on the crane type.

 

5. Runway Rails
Installed on top of building columns or support structures.

Provides the track for the crane's end trucks to move along the length of the bay.

6. Electrical System & Controls
Includes pendant control (push-button pendant) or radio remote control for operation.

Motors for bridge travel, trolley travel, and hoisting.

Limit switches for safe movement.

 

7. Brakes & Safety Devices
Brakes ensure smooth stopping and load holding.

Overload protection prevents lifting beyond 5-ton capacity.

Bumpers at the end of the bridge to absorb impacts.

8. Cabin (Optional for Operator)
Some cranes may have an operator cabin instead of pendant control.

9. Festoon System or Cable Reel
Manages power and control cables for the crane's movement.

10. Buffers & End Stops
Prevent over-travel and collisions at the ends of the runway.

 

11. Crane hook

A Single Girder 5 Ton Overhead Crane with Crane Hook is a common industrial lifting solution designed for medium-duty material handling. Here's a breakdown of its key features and specifications:

Key Components:
Single Girder Bridge – The main horizontal beam that spans the width of the workspace, supporting the hoist and trolley.

Hoist & Trolley – A 5-ton capacity electric or manual hoist moves along the girder via a trolley mechanism.

Crane Hook – Attached to the hoist, used to lift and transport loads (typically forged steel, swivel-type for flexibility).

End Trucks – Wheeled units at each end of the girder that allow the crane to move along runway beams.

Runway Beams – Installed on building columns or freestanding supports to guide crane movement.

Control System – Pendant control (wired or wireless) or cabin-operated for precise load handling.

 

12.Motor

A single girder 5-ton overhead crane typically uses electric motors for hoisting and traveling operations. The motor specifications depend on the crane's design, duty class, and operational requirements. Below are the key motor types and their general specifications for a 5-ton single girder overhead crane:

1. Hoist Motor (Main Lifting)
Power: ~7.5 kW to 13 kW (10 HP to 17.5 HP)

Type:

Geared Motor (with brake): AC induction motor (3-phase) or variable frequency drive (VFD) motor for smoother control.

Duty Class: Typically S3 (40%) for intermittent operation.

Speed: ~1400–1500 RPM (4-pole motor).

Brake: Electromagnetic fail-safe brake for safety.

Voltage: 380V/415V (standard industrial), 220V/240V (smaller setups), or 460V (US standard).

2. Trolley Travel Motor (Cross Movement)
Power: ~0.5 kW to 2.2 kW

Type:

Geared AC motor with brake (if required).

Duty Class: S3 (25-40%).

Speed: ~1400 RPM (adjustable with VFD).

3. Bridge Travel Motor (Longitudinal Movement)

AC induction motor with optional frequency control.

Duty Class: S3 (25%).

Speed: ~1400 RPM.

 

8. Sound and light alarm system and limit switch safety device

A Single Girder 5 Ton Overhead Crane typically includes several safety devices, such as a sound and light alarm system and limit switches, to ensure safe operation. Below are the key details about these safety features:

1. Sound and Light Alarm System
Purpose: Alerts personnel when the crane is in operation or approaching a hazardous condition.

Components:

Buzzer/Horn: Emits a loud audible warning before the crane starts moving or during emergency situations.

Strobe Light/Beacon: Flashing LED or rotating beacon to provide a visual warning.

Activation:

Automatically triggers when the crane is powered on or begins movement.

May also activate when approaching limit switch zones or in case of overload.

2. Limit Switch Safety Device
Purpose: Prevents the crane and hoist from exceeding safe travel limits (end-of-travel) or overload conditions.

Types of Limit Switches:

Hoist Upper/Lower Limit Switch: Stops the hoist when the hook reaches the maximum or minimum safe height.

Trolley Travel Limit Switch: Prevents the trolley from moving beyond the girder's ends.

Bridge (Long Travel) Limit Switch: Stops the crane from moving beyond the runway rails.

Operation:

Mechanical or proximity-based switches cut off power when triggered.

Some cranes use magnetic or encoder-based limit switches for precise control.

Additional Safety Features (Common in 5-Ton Cranes)
Overload Protection: Cuts power if the load exceeds 5 tons.

Emergency Stop Button: Allows immediate shutdown in case of danger.

Undervoltage Protection: Prevents unexpected restarts after power failure.

Anti-Collision System (if multiple cranes operate on the same runway).

 

10. Control Mode

A single girder 5-ton overhead crane typically offers multiple control modes to suit different operational needs. Here are the common control options:

1. Pendant Control (Push Button Pendant)
Description: A handheld pendant with buttons for crane movement (hoist up/down, trolley left/right, bridge forward/backward).

Best for: Standard workshop operations where the operator is near the crane.

Voltage: Usually 24V or 36V (low voltage for safety).

Range: Limited by cable length (typically 5-10 meters).

2. Radio Remote Control (Wireless)
Description: A wireless remote control allows operation from a distance (up to 100m or more).

Best for: Large workshops, hazardous environments, or when the operator needs mobility.

Features:

Frequency hopping (anti-interference).

Emergency stop function.

IP-rated for dust/water resistance.

3. Cabin Control (Operator Cab)
Description: An enclosed or open cabin where the operator sits to control the crane.

Best for: Heavy-duty, frequent, or long-duration lifting tasks.

Features:

Joystick or lever controls.

Better visibility for precise handling.

4. Automatic/Semi-Automatic Control (PLC)
Description: Programmable Logic Controller (PLC) for automated movement.

Best for: Repetitive tasks (e.g., loading/unloading in production lines).

Features:

Pre-set lifting paths.

Sensors for positioning.

5. Dual Control (Pendant + Remote or Pendant + Cabin)
Description: Combines two control modes (e.g., pendant for normal use, remote for emergencies).

Best for: Flexible operations requiring backup control.
