Plant Lifting Jacks

Automatic Welding manufactures hydraulic "run on" lifting jacks for portable crushers,screens and feeders. These cylinders are used to setup plants for the production mode, and lower plant or equipment for travel in short time. The ability to process material while sitting on these jacks is possible without blocking. They are also used to raise and lower large fuel tanks for transport, and aid in the setup of portable scales. Often used now in the design of modular sections of the aggregate plant, separate crushers, screens, sand screws which can be easily setup for different configurations.
