MRW020-E Yale Walkie Stacker Specs & Dimensions (2019 - 2026)

Traction System

The traction system consists of the traction motor, gearbox, and brake. The UL approved traction motor with premium brushes and Class H insulation provides maximum thermal protection. The innovative gear box design incorporates maintenance-free steer bearings.

Traction Motor

A stationary mounted traction motor, integrated motor pinion, and drive axle string guard. The maintenance-free steer bearings are sealed within the gearbox housing and lubricated by the gear oil. The stationary traction motor eliminates power cable tension and flex. The integral pinion and support bearings optimize the gear mesh resulting in a quieter gearbox. The splined coupling allows for quick removal and installation of the traction motor. The drive axle string guard minimizes axle seal damage from shrink-wrap, banding, etc. The electronically released, mechanically applied brake is on top of the traction motor for ease of inspection and maintenance. The brake is controlled by a handle position switch which prevents the truck from moving when the handle is fully raised or fully lowered.

Wheels and tires

The standard load wheel configuration is tandem poly load wheels with two roller bearings per wheel. “Knock-out” axles provide for quick and easy maintenance. The load wheel compound is 92 durometer polyurethane molded over a steel wheel and the wheel measures 4” X 2.8”. A 10” X 5” press-on poly drive tire is standard. The drive wheel is secured to the axle with 5 bolts.

Reach Mechanism

The reach mechanism is computer designed and provides 24 inches of extension. The open carriage design and optimal hose routing provide good visibility. Carriage, load backrest, hook type forks, and optional integral sideshifter tilt all and sideshift together. Reach/retract cylinders are cushioned for smooth operation. All pivot points have high pressure grease fittings for easy maintenance. Overhead rollers are used to evenly distribute the load.

Mast, Carriage and Forks

The Yale mast is available in simplex and triplex configurations for various heights. The trunnion mounted mast design provides for good load distribution and allows for easy service and transport. The hydraulic cylinder incorporates a chrome-plated rod for corrosion resistance. The cylinders are easily serviced and provide integral cushioning for excellent mast channel staging. Velocity fuses are provided to control lowering in the event of hydraulic failure. A manual lowering valve is standard. The standard tilting carriage provides 4° backward/3° forward tilt. Lowering speeds are controlled by a valve in the manifold block. Controlled descent is assured by velocity fuses in each cylinder base. Forks are heat-treated, forged steel with increased thickness in the critical heel section.
