GTC Engineering builds and hires out Recovery Cranes. These cranes are designed as complete modular units which can be transported in standard size elevators, up and down flights of stairs then skated into position. They can be configured to suit many applications. Capacities vary from 7 tonne to 1 tonne, with large winches that allow hoisting on multi-storey buildings. Heavier lifts are possible with Engineering changes and approval.
