SP 3521 Model / Features & Benefits
Power
A 24-volt electrical system.
Drive Unit/Drive Motor
The latest generation of Crown's AC drive motor provides powerful acceleration and fast travel speeds. The drive unit uses spiral bevel and helical gears from motor to drive axle. The drive motor does not rotate, minimizing wear on electrical cables.
Crown's Access 1 2 3™ Comprehensive System Control monitors all on-board sensors, makes decisions based on the sensor readings, and subsequently controls all truck movements. Five modules are in constant communication via CANbus so that information is accessible to the system at all times. Moreover, Access 1 2 3 enables adjustment of truck performance specifications - such as travel speed, plugging, acceleration, coasting and lowering speed.
Fork Assembly
Forged cantilever forks feature Fork Tip Indicators for easier pallet entry.
Operator Controls
Operator controls are designed to ensure four-points of solid contact for the operator, providing a safe and secure environment at heights. Controls are positioned to minimize hand and wrist fatigue.
An information display provides key status data such as selectable traction perfomance profile, steer wheel position, event and service codes, battery discharge indication and wire guidance status.
Right-hand controls include travel, raise & lower, horn and accessories.
Left-hand steering wheel controls the full-time electronic power steering for smooth and precise operation with little effort.
Chassis
Crown's Load Path Stability (LPS) design evenly distributes the weight of the load to the ground, resulting in unmatched stability and comfort at heights.
The chassis incorporates massive bracing, heavy-gauge steel and replaceable bolt-on skid bars. The skirt, doors and battery cover are fabricated from heavy-gauge steel.
Brakes
Crown's patented Intelligent Braking System (IBS) provides smooth, precise braking at all heights by monitoring platform height, travel speed and direction and then applying the optimum combination of motor and friction braking.
Mast
Crown's mast design delivers rock-solid stability and cushioned staging for superior operator confidence at height. Heavy outer C-channels and inner I-beams, tied by massive cross members and vertical mast braces minimize lateral sway and improve front-to-back stability.
Visibility
The operator platform features a large window for excellent visibility. Even at lower elevations, the clear view mast provides an unobstructed sightline for a clear view of pick locations and intersecting aisles.
Speed
Fast acceleration and a top speed of 12 km/h allow operators to quickly move from one pick location to another. Linear speed control gives operators a smooth speed transition as lift heights change.
Operator Safety & Comfort
The large operator platform with full-width overhead guard and safety-interlocked gates provides a safe and secure workstation.
The heavy chassis and reinforced mast minimizes mast sway for a confident feeling when operating at heights.
Crown’s premium anti-fatigue floor mat reduces the effects of vibration and standing fatigue.
Serviceability
The Access 1 2 3™ Comprehensive System Control can be accessed via the display providing real-time troubleshooting capabilities. There is no need to connect to a laptop or handset to check the truck's status, fault history or to calibrate systems.
Crown's InfoPoint™ system simplifies troubleshooting and servicing, reducing the need for schematics, wiring diagrams or service manuals.
Service and parts manuals recognized in the industry as the most user friendly, enabling quick part reference and easy maintenance.
