HLA Attachments HDR5548BO500 Hydraulic Rotating Pallet Fork combines a 5,500 lb rated carriage, 48 in adjustable fork tines, and hydraulic rotation in a heavy-duty material-handling attachment for loaders and skid steers. Powered by a hydraulic cylinder, the carriage rotates smoothly through 180° to provide a full dump to the left. The BO500 mounting configuration fits machines equipped with a universal skid-steer quick-attach interface, making this attachment suitable for lifting, positioning, carrying, and controlled dumping applications where standard fixed pallet forks cannot provide the required movement.
The HDR5548 uses hydraulic-cylinder-powered rotation to deliver smooth, contoured movement. Its 180° left-hand rotation allows the operator to turn and fully dump a load without changing attachments. This capability adds flexibility when handling materials that need to be positioned, inverted, or discharged at the work site.
Operation requires a loader auxiliary hydraulic circuit connected through hydraulic quick couplers. HLA advises that the machine’s auxiliary hydraulics must not be locked continuously in the ON position while using the attachment.
The heavy-duty carriage has a rated capacity of 5,500 lb and is paired with 48 in fork tines. The tines are adjustable, allowing their spacing to be configured for different pallets, loads, and handling tasks. The HDR55 carriage is compatible with maximum tine-length options of 42, 48, or 54 in; this configured HDR5548 model is supplied with the 48 in tine length.
The catalogue weight for the HDR5548 base attachment is approximately 860 lb. This published figure should be considered when matching the attachment and intended load to the operating capacity of the host loader or skid steer.
This configuration carries HLA mounting code BO500, identifying a universal skid-steer quick-attach interface. It is intended for compatible loaders and skid steers equipped with that mounting system. The quick-attach configuration provides a practical connection for operators who need to change between material-handling attachments and other compatible tools.
The HDR5548BO500 is compatible with loaders and skid steers equipped with the universal skid-steer quick-attach interface represented by HLA mounting code BO500. The host machine must also have an auxiliary hydraulic circuit to operate the rotation cylinder.
An optional HK90 hose kit provides 90 in hoses with flat-faced couplers. An optional SHMK spring hose mount kit is also available to support hydraulic hose routing.
