Challenger 44050 — 50,000 lb ALI/ETL Certified Heavy-Duty 4-Post Lift
The Challenger 44050 is a 50,000 lb heavy-duty 4-post drive-on lift built for commercial fleet maintenance facilities servicing Class 6–8 vehicles. Chain-driven with a 15HP three-phase motor, 10 pneumatic air lock positions, 32-inch-wide adjustable runways, and 73 inches of rise height — this is the same platform as the 60,000 lb 44060 at a lower capacity rating for operations that don't need the full 30-ton lift. The 44050 is ALI and ETL Certified, comes in three track lengths (25', 30', and 35'), and shares the industrial-grade construction that makes the Challenger heavy-duty 4-post lineup the standard in fleet maintenance.
Chain-Driven Heavy-Duty Lifting System
The 44050 uses a chain-driven power train — not cables or screws. A 15HP, 230–460V three-phase motor powers the hydraulic system, raising a full 50,000 lb load to maximum height in approximately 75 seconds. The equalizer chain system ensures all four columns rise and descend at the same rate, keeping the vehicle level throughout the lifting cycle. The three-phase power requirement reflects the industrial-grade infrastructure these lifts operate in — this is equipment for commercial facilities with dedicated electrical service, not residential garages.
10 Pneumatic Air Lock Positions
The 44050 features 10 pneumatic safety lock positions, providing a wide range of working heights from just above runway level to the full 73-inch rise. The pneumatic lock system requires compressed shop air to engage and disengage — standard infrastructure in any commercial maintenance facility. Unlike mechanical locks that require manual release at each column, the air lock system allows the technician to control all four locks from the power unit station. This is critical when working under vehicles weighing up to 25 tons — safety lock engagement must be positive, reliable, and verifiable from a single control point.
32-Inch Wide Runways with Adjustable Track Spacing
The 44050's 32-inch-wide runways provide a stable driving surface for the widest commercial vehicles, from standard single-rear-axle trucks to dual-rear-axle configurations, refuse trucks with side-loading arms, and transit buses. Track spacing adjusts from 36 to 58 inches between runways, allowing shops to configure the lift for their specific vehicle mix. The runways sit 14 inches above floor level — low enough for fixed approach ramps while providing clearance for the chain-driven lift mechanism underneath. Rub blocks protect the columns from contact damage during vehicle positioning.
Installation Requirements
The Challenger 44050 requires a concrete slab at least 5 inches thick, steel reinforced, rated at 3,000 PSI or higher, and cured for a minimum of 28 days. The floor must be level within 2 inches between any two post locations and free from cracks and seams. Anchor bolts require a minimum of 5 inches from the slab edge. The recommended minimum bay size for the standard-length 44050 is 26 feet 1 inch wide by 42 feet 4 inches long. A minimum ceiling height of 16 feet is recommended. The 44050 requires 230–460V, three-phase power with a 30-amp circuit. The lift ships without hydraulic fluid — approximately 20 gallons of AW-32 hydraulic oil are required at setup. The motors are not sealed against weather or moisture, so the lift must be installed indoors in a climate-controlled environment.
