The primary options for suspending a hoist are a fixed Beam Clamp or one of three mobile systems: a Push Travel Trolley, a Geared Travel Trolley, or an Electric Travel Trolley. Your choice is determined by whether the load must move horizontally after being lifted and, if so, the required level of control, frequency of movement, and weight of the load.
The fundamental decision is not just about the hoist, but about the required movement of the load. First, determine if your lift point needs to be stationary or mobile. If mobile, your choice then comes down to a trade-off between manual simplicity, mechanical precision, and powered efficiency.
The Foundational Choice: Fixed vs. Mobile Suspension
Before evaluating different types of trolleys, you must answer one critical question: Does the load only need to move up and down, or does it also need to travel horizontally along a beam?
The Beam Clamp: For Stationary Lifting
A beam clamp is a simple, robust device that affixes your hoist to a single, stationary point on an overhead I-beam.
Its sole purpose is to provide a secure anchor for vertical-only lifting. Once attached, there is no horizontal movement possible along the beam.
This is the ideal choice for dedicated workstations, such as a maintenance bay or a specific loading dock, where the work is always performed in the same spot.
Choosing Your Method of Travel: Trolley Systems
If your application requires moving the lifted load horizontally along a beam, you need a trolley. The three types of trolleys offer different methods of control and are suited for different applications.
The Push Travel Trolley: Simple Manual Movement
A push travel trolley is the most basic mobile option. The operator simply pushes or pulls the load itself to move the trolley along the beam.
This system is best suited for lighter loads and infrequent moves over short distances. It offers simplicity and low cost but lacks precision and can be physically demanding with heavier loads.
The Geared Travel Trolley: Precise Manual Control
A geared travel trolley is also manually operated, but movement is controlled by pulling a hand chain. This chain engages a gearbox, which turns the trolley wheels and moves it along the beam.
The gearing provides a mechanical advantage, making it much easier to move heavy loads and allowing for very precise positioning. It is an excellent choice when you need to spot a load carefully without the complexity of an electric system.
The Electric Travel Trolley: Powered for Efficiency
An electric travel trolley uses a motor to move along the beam, controlled by a push-button pendant (often the same one that operates the hoist).
This is the premier solution for applications involving heavy loads, frequent use, or long travel distances. It minimizes operator fatigue and maximizes speed and efficiency, making it standard in high-production environments.
Understanding the Trade-offs and Limitations
Selecting the right suspension is a matter of balancing cost, control, and operational demand. Making the wrong choice can lead to inefficiency and safety hazards.
Cost vs. Capability
There is a clear hierarchy in both cost and capability. The beam clamp is the least expensive, followed by the push trolley, the geared trolley, and finally the electric trolley, which is the most expensive. The initial investment directly correlates with the level of control and efficiency you gain.
Speed vs. Precision
A push trolley is fast for light loads but offers poor precision. A geared trolley delivers exceptional precision but is inherently slow. An electric trolley provides speed, but achieving fine control may require more advanced (and costly) variable frequency drive (VFD) controls.
Operator Strain and Safety
Relying on a push trolley for loads that are too heavy or moved too frequently creates a significant risk of musculoskeletal injury for the operator. Geared and electric trolleys drastically reduce this physical strain, improving workplace safety and ergonomics.
Making the Right Choice for Your Application
Your operational needs should be the deciding factor. Analyze your most common lifting tasks and select the system that best matches the workflow.
- If your primary focus is fixed-point lifting: A beam clamp is the most direct and cost-effective solution.
- If your primary focus is moving light loads infrequently: A push travel trolley offers simple horizontal movement at a low cost.
- If your primary focus is precise positioning of heavier loads: A geared travel trolley provides the control needed to spot loads accurately without a motor.
- If your primary focus is speed, efficiency, and frequent use: An electric travel trolley is the superior choice for high-demand environments.
Selecting the correct suspension method ensures your lifting operations are not just possible, but also safe, efficient, and perfectly suited to the task.
Summary Table:
| Suspension Type | Best For | Key Characteristic |
|---|---|---|
| Beam Clamp | Fixed-point, vertical-only lifting | Simple, cost-effective, stationary |
| Push Trolley | Light loads, infrequent short moves | Manual push/pull, low cost |
| Geared Trolley | Precise positioning of heavy loads | Manual chain control, mechanical advantage |
| Electric Trolley | Heavy loads, frequent use, long distances | Motorized, push-button control, high efficiency |
