RC 5755-40 Crown electric forklift specs & dimensions (2022 - 2026)

Crown Drive System

Crown has applied the latest generation AC drive system, enhanced with Access 1 2 3 technology. The demand for high efficiency systems that closely match customer torque requirements is met with this generation control system. Crown-manufactured, independently controlled, AC drive motors are specifically designed to optimize system integration between the traction and braking controls. Crown’s Access 1 2 3 technology provides optimum performance and control by offering a communication interface for operators and technicians, intelligent coordination of lift truck system and simplified service with advanced diagnostics.

e-GEN™ Braking System

Variable regenerative motor braking is optimized and virtually eliminates brake maintenance. The appropriate amount of stopping force is applied to match operator brake input and the current operating conditions of the truck. The closed loop Access 1 2 3 traction control will keep the truck stable until a travel input is requested, even when operating on a grade. Automatic electric parking brakes activate when the operator releases the brake pedal, a travel request has not been registered or battery power has been disconnected.

Steering

Load-sensing hydrostatic steering is an on-demand system which reduces energy consumption. Smooth, quiet steering control with minimal operator effort required at the steer tiller. Steer tires rotate 182° for maximum maneuverability. Crown’s hydrostatic steering system is simplified with significantly fewer parts, thus reducing maintenance requirements.

Mast Assembly

Crown-manufactured mast assembly utilizes a "flush-face" interlocked I-beam design to improve visibility and reduce truck length. Roller bearing studs are welded on both sides of the rails for maximum strength, and roller bearings are centered on the rail. The I-beam cross section of the rail is designed with tie bars that wrap around the rails for added strength and to resist off-center load forces. "In-line" hose routing opens up visibility, while cylinders are placed to the sides to create a high visibility design. The mast has four points of attachment to the truck for good load distribution, with the mounting points located outside the frame where tilt cylinders attach. Additionally, tilt cylinders are placed at the front of the mast to reduce center load distortions, and two large diameter studs secure the mast to the drive units.

Drive Units

Two Crown-manufactured independent double reduction planetary gear drives offer 27 to 1 gear reduction. The first and second reduction use helical gears for low noise and efficiency. The drive unit operates on splash lubricated in an oil bath.
