HLA Attachments HDR55BO500 5,500 lb Hydraulic Rotating Fork Carriage is a heavy-duty material-handling attachment designed for loaders with a universal skid-steer quick-attach carrier. Combining a 5,500 lb carriage capacity with smooth, hydraulic cylinder-powered rotation, it allows the operator to rotate a compatible fork load through 180 degrees for a full dump to the left. This carriage-only configuration is supplied without fork tines, allowing adjustable tines to be selected separately for the intended application.
The HDR55 rotating carriage is designed for jobs that require more than conventional lifting and carrying. Its hydraulic rotation mechanism provides smooth, contoured movement through a 180-degree range, enabling material to be dumped to the left without relying solely on the loader’s standard attachment movement.
Rotation is powered by a hydraulic cylinder and controlled through the loader’s auxiliary hydraulic system. This makes the carriage suitable for material-handling applications where controlled rotation and left-side discharge can improve positioning, unloading, or workflow.
This HDR55BO500 model is supplied as a carriage only, less fork tines. It accepts adjustable fork tines, but the tines are not included and must be selected separately. This configuration is useful when the required tine size or setup needs to be matched to a particular handling application.
The carriage is rated for a capacity of 5,500 lb. Actual safe operating capacity must also account for the selected fork tines, loader capacity, attachment position, load centre, hydraulic capability, and the operating limits specified for the loader.
The BO500 mounting configuration provides a universal skid-steer quick-attach interface. It is intended for loaders equipped with a universal skid-steer quick-attach carrier, providing a familiar connection format for compatible loader configurations.
The HDR55BO500 is compatible with loaders equipped with a universal skid-steer quick-attach carrier. HLA identifies the BO500 interface for numerous loader configurations using a skid-steer-style carrier. Confirm the loader’s carrier type, operating capacity, hydraulic capability, and attachment requirements before installation or use.
Loader auxiliary hydraulics are required to operate the carriage’s rotation cylinder. Hydraulic flow and pressure requirements are not specified for this configuration. The hydraulic connections and loader output should be confirmed before installation. An optional HK90 hose kit provides 90-inch hoses with flat-faced couplers, while the optional SHMK spring hose-mount kit is available for hose support.
