Drive Unit/Brake
An AC traction motor, combined with a heavy-duty gearbox with a helical spur input gear, provides quiet operation and powerful performance.
Regenerative motor braking is activated under downhill conditions, during plugging or when the directional control is returned to neutral. An electromagnetic brake, mounted on top of the drive motor, serves as the parking brake and applies when the control handle position moves from the operating zone to brake zone during truck operation.
Visibility
Two and three stage masts feature angled cross bracing and lift cylinders located behind nested I-beams for maximum visibility. A low-profile power unit and centrally located control handle further enhance visibility.
Maneuverability
The SH 5500 Series features electronic power steering for effortless steering and a brake override that enables slow-speed travel with the handle in a near-vertical position. These features improve maneuverability and handling in tight areas.
Control Handle
Crown’s robust X10® handle places all control buttons in the optimum position for ease of operation with either hand and to minimize hand and wrist movements. An ergonomic forward/reverse thumb wheel allows for precise maneuvering.
The Access 123® display simplifies service for technicians by providing advanced diagnostics without handsets. Crown’s InfoPoint® System compliments Access 123 diagnostics by providing a Quick Reference Guide, on-truck component maps and information nuggets to further simplify troubleshooting.
Removable steel power unit doors are hinged for ease of opening, providing excellent accessibility to the distribution panel and all other components. A hinged steel top cover allows easy access to the battery to perform inspections.
Crown’s service and parts manuals have been recognized in the industry as the most user-friendly, enabling quick part reference and easy maintenance.
