Understanding the different types of lifting accessories for cranes is important in order to choose the right piece of equipment. Each categories has a very specific job and works best with certain types of loads.
Overview of common underhook accessories:
Lifting Beams
Lifting beams are horizontally placed structures that allow a load to be evenly distributed across multiple locations. These are ideal for raising long and heavy objects that require support at various points. They come in various configurations, such as fixed, adjustable, and telescopic, catering to different lifting requirements.
Fixed Lifting Beams
A fixed lifting beam is a non-adjustable structure with a predetermined length They are used when the distance between lifting points is consistent. These beams are sturdy and reliable, providing a stable lift for heavy loads.
Adjustable Lifting Beams
Adjustable lifting beams offer flexibility providing a range of applications to handle loads in different lengths. The adjustable sizing of the fork arms enables them to be used in different lifting points, making them a useful tool for environments where load dimensions are not constant and change frequently.
Telescopic Lifting Beams
Telescopic lifting beams can extend and retract to accommodate different load sizes. This function makes them adaptable to use and can adjust based on specific lifting requirements especially where space constraints are a concern.
Spreader Bars
Spreader bars function similarly to lifting beams but are designed to spread the load over a wider area. This keeps the load stable and balanced, making them ideal for lifting large cumbersome objects. They are especially useful in situations where the load’s center of gravity is not centralized.
Single-Point Spreader Bars
Single-point spreader bars are designed for loads with a single lifting point. They distribute the load evenly, ensuring stability during lifting. These bars are simple to use and are suitable for straightforward lifting tasks.
Multi-Point Spreader Bars
Multi-point spreader bars have multiple lifting points, providing enhanced stability for larger and more complex loads. These bars are used in situations where the load needs to be balanced across several points to prevent tipping or shifting.
Plate Clamps
Plate clamps are used for lifting and handling heavy, flat materials like steel plates. They come in various designs, including vertical, horizontal, and universal clamps. These clamps provide a secure grip on the material, ensuring it is lifted safely without slipping.
Vertical Plate Clamps
