1653.5 lbs Impressive Load Capacity: This underhoist support stand equipped with wheels is lightweight at only 25.4 lbs / 11.5 kg but can support a remarkable 1653.5 lbs / 0.75 t. The sturdy tubular steel frame helps prevent deformation or twisting. At least 2 stands are required for use and can support most small cars and similar vehicles. Dual Quick Height Adjustment: The holes on the main post of the jack stand are used to lock in the primary height levels, and the threaded rod assists in adjusting the height. The spin handle incorporates a thrust bearing, making it easy to raise and lower, even under the extreme pressures of a heavy load. The height adjustment range is 38.4" - 75.4" / 975 - 1915 mm, catering to the bottom clearance requirements during most maintenance tasks. Safety and Stability: A thickened 0.2" / 6 mm circular base and sturdy 0.1" / 3 mm triangular gussets enhance load stability, while the U-shaped tray with rubber padding provides secure, non-slip support without causing damage. This design of our hoist stand ensures a firm and stable hold, preventing the vehicle from wobbling. Self-Locking Feature for Easy Operation: The threaded screw rod provides a self-locking function to prevent the stand from lowering without assistance. Adjusting the under hoist jack stand under the vehicle is also very secure. The rubber handle provides a comfortable grip. Versatile Applications: The screw jack provides partial support for positioning vehicle components during installation and removal processes. It provides technicians with added height assistance when working on components such as transmissions, CV joints, radiators, drive shafts, exhaust systems, and catalytic converters, among others.
