Technical Narrative
The Cat® WB641689 Self Propelled Mobile Scissor Lift Table is a fully electric, battery-powered lift-and-transport platform designed for heavy-duty material positioning in manufacturing, warehouse, and maintenance environments — a double-scissor mechanism that raises a 40 × 27-inch platform to 72 inches from a 20½-inch lowered height while carrying evenly distributed loads of up to 3,000 lb. Powered by a 24V / 50 Ah battery driving both a 1.2 kW drive motor and an 0.8 kW lift motor, the WB641689 self-propels on 8-inch polyurethane wheels at up to 2.2 mph and completes a full lift cycle in 15–25 seconds — repositioning heavy dies, molds, sheet metal, large panels, and similar loads without manual push effort or crane overhead. The fully electric drive and lift eliminates pneumatic or manual hydraulic hand-pumping at the operator position.
The ergonomic tiller handle features a dual butterfly switch for drive control and push-button lift/lower operation, keeping both operator hands on the handle during positioning moves. Four integrated safety systems protect the operator and the load: two emergency stop buttons (one on the tiller, one belly-button style on the chassis), anti-collision wheels that absorb low-speed impact, a balance assistance system for enhanced load control, and a battery level indicator with charging indicator lights. The heavy-gauge steel frame carries a chip-resistant powder coat finish in Cat® Yellow and Black. Meets ANSI MH29.1-2020. Limited 5-Year Warranty. Assembly required.

Laboratory and Industrial Applications
The Cat® WB641689 Self Propelled Mobile Scissor Lift Table is specified for heavy-load positioning applications requiring a self-propelled, battery-powered platform that combines transport and precision height adjustment in a single unit, including manufacturing facility die and mold positioning where 3,000 lb loads must be moved from storage to press or machining position without a forklift, warehouse heavy-pallet positioning and ergonomic height adjustment for order picking and receiving operations, maintenance and repair facilities requiring a mobile work platform that elevates heavy components to technician working height, sheet metal and panel fabrication facilities requiring a motorized transport-and-position platform for heavy sheet stock and formed panels, distribution center cross-dock positioning where heavy loads require both horizontal transport and vertical positioning, industrial laboratory facilities handling heavy analytical equipment or prototype assemblies requiring repositioning between workstations, machine shop tooling and fixture staging requiring precise height-adjustable positioning without overhead crane use, and any industrial or laboratory environment where a 3,000 lb capacity, fully electric, self-propelled double-scissor lift table that raises to 72 inches and travels at 2.2 mph is the correct material handling specification.

Frequently Asked Questions
What does self-propelled mean for the WB641689, and what is the practical battery range per charge?
Self-propelled means the WB641689 drives itself under battery power — the operator steers with the ergonomic tiller handle using the dual butterfly switch for forward and reverse, rather than pushing a manually-operated unit. The 24V / 50 Ah battery powers both the 1.2 kW drive motor and the 0.8 kW lift motor. The unit is rated for 80 complete lift cycles per charge at a lift time of 15–25 seconds per cycle. A full recharge from the included 24V / 8A charger takes approximately 10 hours. The battery level indicator and charging indicator lights on the tiller display current charge status. For full charge-cycle usage in a production shift, plan for an overnight recharge.
What is the difference between the platform dimensions and the overall dimensions of the WB641689, and how much floor clearance does the unit need?
The platform dimensions (40 × 27 in) describe the usable load surface. The overall dimensions (54.3 × 29 in footprint, 46 in height when lowered) describe the full unit envelope including the tiller handle, scissor mechanism housings, and anti-collision wheel protrusions. For aisle and doorway planning, use the 54.3 × 29 in overall footprint. The unit lowers to 20½ in platform height (46 in total unit height at the lowest position), which determines clearance requirements for loading from ground level or low dock positions. For standard 7-ft (84 in) ceiling clearances, the 72-in raised height leaves approximately 12 inches of overhead clearance, which is adequate for most positioning operations but should be confirmed before deployment in low-ceiling environments.
