Swivel hoists lift and rotate loads horizontally and vertically, with various designs for different needs. Load limitations must be noted to avoid overloading. Technicians should be aware of the hoist’s tendency to rotate and ensure safety measures are in place. Manufacturers can install and provide safety training.
A swivel hoist is a lifting tool that also rotates to move a load both horizontally and vertically. Numerous designs can cover different needs, from warehouse applications to dockside loading and unloading. The lifting capacity of a swing hoist can vary and it is important to note load limitations to avoid overloading the hoist. Special training may be required to operate some types of swing hoists.
One design involves the use of a swivel hoist ring. The hoist itself remains stationary in operation, but the swivel ring allows the load to rotate. Swivel hoist rings can be attached to a number of hoist models and styles for conversion if this functionality is desirable. The hoist shackle has load specifications and these should be noted along with the limitations on the hoist itself; a heavy duty ring cannot compensate for a relatively weak hoist.
Another design uses a swivel base or arm. This type of slewing block can usually rotate in a full circle to move a load and can operate with the boom extended or closed. The weight limits can be variable and can also depend on the position of the arm in space. It can operate from a fixed base or a ceiling lift installation.
While using such hoists, technicians must be aware of the tendency of the device to rotate and must factor this into their decisions. A swivel hoist shackle may be lockable to prevent rotation when it is not desired, but can otherwise rotate freely, potentially posing a hazard to personnel working around the hoist. Technicians should ensure that the area around the hoist is clear and should be aware of the range of the hoist while in operation so they know where the boundaries of the safety zone are.
Manufacturers of swivel lift products can also install them, usually for an additional fee. Some may even provide safety training and instructions on how to use their products safely and reliably. For occupational safety reasons, personnel working with and around the hoist should be trained in its operation and limitations to ensure that oversized or excessive loads are not used. In the case of hire hoists supplied upon request for specific project needs, a business may be able to hire an operator if they do not have a staff member capable of safely operating a slewing hoist.
