Rotary Lift offers three new configurations of its family of heavy-duty pit lifts, with capacities ranging from 30,000 to 48,000 pounds. The three configurations are: suspended on rails at the top of the pit, free rolling on the pit floor, or rail mounted on the pit floor. Designed and built to withstand the toughest, most rigorous applications, the lifts can engage and raise the axle for wheel and hub service, or can be used to assist in the removal of the transmission or other heavy undercarriage components. The controls on all three models offer two raising speeds fast for positioning the lift and slower for the actual lifting. The lifts are also equipped with manual hydraulic handle (or foot pedal) for precision adjustments. The piston rod and pump piston are hard chrome-plated and a patented oil-submersion system bathes the cylinder in oil to protect it against corrosion.
