Solid-steel safety lock bars engage automatically and continuously during ascent, transferring working load onto mechanical locks when secured. This helps reduce reliance on hydraulic pressure while technicians work beneath or around the raised vehicle. Stainless-steel pneumatic cylinders release the locks during descent with the push of a button, while Zerk grease fittings at hinge points help protect critical wear areas. Four durable cushioned-rubber contact blocks are included for fast vehicle setup at the proper lifting points.
