Single Beam Overhead Crane For Workshop
Products Description
Single beam overhead cranes are essential material handling systems designed for efficient, safe, and cost-effective lifting and transportation in workshops. These cranes consist of a single bridge girder supported by end trucks that move along runway beams, making them ideal for small to medium-sized workshops with moderate lifting needs.
1.Single Girder Design
Uses a single bridge beam (main girder) supported by two end trucks.
More economical and lighter than a double girder crane, suitable for medium-duty applications.
2.Capacity
Rated for 10 metric tons (10,000 kg), making it ideal for warehouses, workshops, and manufacturing plants.
3.Span & Lifting Height
Span (width of coverage): Typically ranges from 5m to 25m, depending on building structure.
Lifting Height: Adjustable (usually 6m to 18m), based on facility needs.
4.Hoisting Mechanism
Equipped with an electric hoist (chain or wire rope) that travels along the bridge beam.
Common brands include Konecranes, Demag, ABUS, or CMCO.
5.Control System
Pendant control (wired remote) or radio remote control for safe and precise operation.
Can be integrated with variable frequency drives (VFDs) for smoother movement.
6.Runway System
Moves on steel rails mounted on runway beams (top-running or underhung).
Top-running is more common for heavy-duty applications.

Pictures & Components
1.Main beam
Main Girder (Single Beam)
The primary load-bearing structure, usually made of welded steel (box-type or I-beam design).
Supports the hoist and trolley while spanning the width of the workshop.
2.End Carriages (End Trucks)
Located at both ends of the main girder.
Equipped with wheels that run on the runway rails.
Include drive mechanisms (motors, brakes, and gearboxes) for crane movement.

3.Hoist Unit
The lifting mechanism, which can be:
Electric Chain Hoist: Compact, suitable for light to medium loads.
Wire Rope Hoist: More durable for heavy-duty lifting.
Includes a motor, brake, gearbox, drum (for wire rope), or sprocket (for chain).

4.Trolley
Moves the hoist along the length of the main girder.
Can be manual (push-operated) or motorized (electric drive).
5.Runway System
Consists of runway beams (supported by columns or building structure).
Runway rails (typically steel tracks) guide the crane's movement.
6.Electrical System
Control Panel: Manages crane operations (lifting, traversing).
Power Supply: Usually via festoon system (cable reels) or busbar system (for cleaner power delivery).
Limit Switches: Prevent over-travel of the hoist and trolley.
Remote Control / Pendant Control: Allows operator to control the crane from a safe distance.
7. Safety Components
Overload Limiter: Prevents lifting beyond rated capacity.
Emergency Stop Button: Instantly halts crane operation.
Bumpers / Buffers: Absorb impact at the ends of the runway.
Anti-Sway Device (optional): Reduces load swing for precision lifting.
.
8. Additional Optional Features
Variable Frequency Drive (VFD): For smooth acceleration/deceleration.
Crane Lights & Alarms: Enhances safety in busy workshops.
Explosion-Proof Design: For hazardous environments.
Automation Integration: Can be linked to workshop automation systems.
