James Contract Supplies Pty Ltd (JCS) is a privately owned and operated South Austrlaian business with a staffing strength of some 29 employees. JCS was established in September 1985, solely to engage in the manufacture of Stainless Steel purpose built vessels and equipment.

In September of 1986, frustrated by transport and crane hire prices and service, JCS purchased a crane, prime mover and tank float which today has expanded to a fleet of cranes up to and including 140 tonne, various prime movers and floats up to 200 tonne capacity with service Australia wide. The company was restructured and the two divisions were formed.
