MAHA USA's new wireless mobile column lift is the only wireless lift designed with a re-circulating ball-screw lifting mechanism. Unlike hydraulic lifts, MAHA USA's unique ball screw design eliminates fluid leaks and synchronization problems and will operate at any temperature, inside or outside. Operating on long lasting, rechargeable batteries, available capacity options include 16,000 lbs or 18,000 lbs per column with the ability to communicate on up to 10 different frequency channels, allowing operation of multiple sets in the same area.
