Single flange wheels and trolley systems are essential for safe, efficient materials handling. When used correctly, they allow smooth load movement, prevent derailment, and minimise accidents. Choosing the right system and using it properly helps protect both workers and equipment from unnecessary risk.

What Are Single Flange Wheels and Trolley Systems?

In lifting and materials handling, single flange wheels and girder trolley systems are key components that enable the controlled movement of loads along a beam or rail.

• Single flange wheels guide and stabilise the trolley, preventing it from slipping or derailing.
• Trolley systems support and move suspended loads horizontally, often in combination with a hoist.

Together, they create a safe and stable lifting path, reducing manual strain and ensuring precise positioning of heavy materials.

Single flange wheels provide guidance, while trolleys provide movement.

Why Does Proper Use Matter for Safety?

Improper use or poor-quality girder trolley components are among the leading causes of lifting accidents. A misaligned wheel, overloaded trolley, or uninspected track can quickly result in dropped loads, equipment damage, or worker injury.

The correct use of single flange wheels and girder trolley systems ensures:

• Even load distribution across the beam
• Smooth travel and controlled movement of the suspended load
• Reduced friction and wear on both wheel and beam
• Improved stability, especially during lifting or stopping

Proper use minimises risk by ensuring smoother, safer, and more predictable load handling.

How Do Single Flange Wheels Work?

Single flange wheels feature one raised edge (or flange) that guides the wheel along the track and prevents lateral movement. The other side of the wheel remains flat to allow for smooth rolling and minor alignment adjustments.

These wheels are commonly found on beam trolleys, gantries, cranes, and rail systems, where they support heavy vertical loads while maintaining horizontal mobility.

Key Features Include:

• Flanged Edge: Keeps the trolley aligned on the beam
• Hardened Steel Construction: Provides durability under heavy loads
• Precision Bearings: Reduce friction for smooth operations
• Compatibility: Works with both straight and curved beam systems

Single flange wheels keep trolleys safely aligned and running smoothly along their path.

What Are the Main Types of Trolley Systems?

Trolley systems come in several configurations to suit different load capacities and applications.

• Push Trolleys: Moved manually along the beam; ideal for lighter loads
• Geared Trolleys: Operated via a hand chain, providing precise control
• Electric Trolleys: Motor-driven for heavy loads or high-frequency use

Each trolley type uses wheels (often with single flanges) that roll along the beam flange, distributing weight evenly and maintaining stability.

Benefits of Using Trolleys:

• Enables horizontal movement without manual lifting
• Allows safe and accurate load positioning
• Reduces operator fatigue and risk of musculoskeletal injury
• Supports integration with hoists for vertical lifting

The right trolley type provides safer, smoother load handling and helps prevent accidents.
