Each different four-post model produced by Rotary Lift offers a different lifting capacity. A rotary lift's lifting capacity refers to the maximum amount of weight it can safely lift. The SM18 and SM18L rotary lifts offer an 18,000-pound lifting capacity. Lifting capacity on the SM300, SM301 and SM302 rotary lifts is 30,000 pounds. The RFL25 model of rotary lift offers a 25,000-pound lifting capacity. Lifting capacity on the 40000HDL is 40,000 pounds. The 50000HDL offers a 50,000-pound lifting capacity, while the 60000HDL offers a 60,000-pound lifting capacity.
The motors fitted into the SM18 and SM18L models offer 2-horsepower outputs and can rise to maximum height in 100 seconds. SM300, SM301, SM302 and RFL25 models are fitted with 4-horsepower motors that can raise a workload to maximum height in 105 seconds. The 40000HDL and 50000HDL models feature two, 2-horsepower engines that also reach maximum height in 100 seconds. The 60000HDL heavy-duty, four-post rotary lift is fitted with two, 3-horsepower engines that lift to a max height in 110 seconds.
