When an application calls for synchronous lifting and pushing of a heavy load, rack and pinion jacks are an easy-to-use, economical and effective option. They combine a simple structure, robust design and a wide range of lifting forces, making them highly versatile and particularly attractive for installation in tight spaces and harsh environments. In fact, rack jacks can be installed as a complete system with many configurations, connected to air cylinders and motors, to guide forces to wherever they are needed in complex applications.
