The TC 25 has been developed by the company in conjunction with the engineering department of the University of Ulster, Jordanstown to cater for the needs of customers on small-scale construction sites.

Mantis said: “Ease of mobility, siting and erection were all important factors to builders of one-off houses and those erecting timber frame and light steel frame structures.”

The crane is a self contained unit built on a road going chassis with fixed ballast so that one articulated tractor unit can move the 20t rig to a jobsite in a single journey. The TC 25 can deliver a 1,000kg load to 20m or a 750kg load to 25m at a hook height of 19m.
