SHR 5540-1.6 TT Crown Walkie Stacker Specs & Dimensions (2012 - 2022)

Drive Unit / Brake

Heavy-duty gearbox with helical spur input gear for quiet operation. Regenerative motor braking is activated under a downhill condition, during plugging or when the directional control is returned to neutral. An electro-magnetic brake, spring applied and electrically released, is mounted on top of the drive motor. The electro-magnetic brake serves as the parking brake and applies when the control handle position moves from the operating zone to the brake zone during truck operation.

Operator Controls

Crown’s robust X10 handle places all control buttons in the optimum position for ease of operation with either hand and to minimise hand and wrist movements. An ergonomic forward/reverse thumb wheel allows for precise maneuvering. The control hand grips are urethane covered for insulation from cold and vibration with integrated horn buttons for easy activation. The handle contains a safety button which reverses the direction of the truck should the button touch the operator. A rabbit/turtle switch incorporates two levels of programmable travel performance so operators can select the setting that matches their experience level or application requirements. An exclusive brake override feature allows slow speed travel with the handle near vertical, improving maneuverability in tight areas.

Performance

The SHR 5500 Series incorporates the latest generation AC drive systems enhanced with Access 1 2 3 technology. Crown’s Access 1 2 3 technology continuously monitors truck systems and adjusts system parameters to deliver optimum performance and control. The Access Display provides a convenient interface for operators, keeping them informed of any changes impacting truck performance and allowing them to choose from three performance profiles when enabled. Programmable performance settings enable authorised personnel to tune the lift truck to different operator skill levels or to meet specific application requirements. In addition, up to 25 PIN codes can be assigned to individual operators and matched to one of the pre-programmed performance profiles if desired. Electronic power steering allows the operator to manoeuvre heavy loads in tight spaces throughout the day while minimising fatigue. The ramp hold feature uses the motor to prevent truck movement when the brake is released and no travel command is present, while the ramp speed control feature ensures that actual travel speed matches requested travel speed.

Electrical System

A heavy-duty 24-volt fused electrical system utilises microprocessor controls for maximum energy efficiency, reduced maintenance and infinite speed control capability. Access control modules for travel, lift and steer are sealed from dirt, dust and moisture for trouble-free operation.
