Product Description

Underslung cranes, also known as under-hung, under-running, or suspension cranes, are a type of overhead crane designed to maximize headroom and provide unobstructed lifting in facilities with limitations. Here's a detailed breakdown of their key features and applications:

Design and Functionality:

• Suspended Movement: Unlike traditional overhead cranes with a bridge supported from above, underslung cranes have their bridge and trolley assembly suspended from an elevated track beam. This track beam is typically secured to the ceiling or building's structural supports.
• Hoist and Trolley: The bridge carries a trolley that travels along its length. This trolley holds the motor-driven hoist, which includes the hook and lifting mechanism for raising and lowering loads.
• Space Optimization: The key benefit of underslung cranes is their ability to operate with minimal headroom required. This allows for maximum use of vertical space within a facility.

Applications:

• Low-headroom Buildings: Underslung cranes are ideal for facilities with limited headroom, such as warehouses with existing structures or buildings with low ceilings.
• Complex Layouts: They are well-suited for buildings with complex layouts where installing columns for a traditional overhead crane might be impractical.
• Maximizing Floor Space: By keeping the crane bridge suspended from above, underslung cranes free up floor space, allowing for better utilization of the area beneath the crane for machinery, storage, or vehicle movement.
• Wall Clearance and Cantilever Options: Underslung cranes offer better side approach clearances compared to top-running cranes. Additionally, some models can be designed with cantilevered beams, allowing the hoist to travel beyond the runway track for increased lifting reach.

Benefits of Underslung Cranes:

• Space Optimization: Maximizes headroom and floor space for better facility utilization.
• Versatility: Adaptable to complex building layouts and low-clearance environments.
• Unobstructed Lifting: Provides clear lifting areas without columns or bridge structures in the way.
• Easy Maintenance: The suspended design often allows for easier access to the crane bridge and components for maintenance.

Things to Consider When Choosing an Underslung Crane:

• Capacity: The maximum weight the crane can safely lift.
• Span: The distance the crane bridge can travel along the runway.
• Headroom: The available clearance between the highest point of the load and the ceiling or overhead structure.
• Building Structure: The strength of the ceiling or supporting structure to handle the suspended crane weight.
• Application: The specific lifting tasks and required reach within the facility.

By understanding these factors, you can determine if an underslung crane is the right solution for your lifting needs and get the most out of its space-saving functionality.
