Description

MAIT has developed a line of HYDRAULIC CRAWLER CRANES with lattice boom, for all type of applications. The cranes are very suitable to be used in construction jobsites, due to their crawler base; a typical utilization is in foundation works, for lowering reinforcement cages, concrete pipes, etc..
Various lattice booms lengths are available for each crane model.
All the cranes are mounted on Caterpillar excavators.
The hydraulic system of the cranes can be utilized not only for the standard crane’s lifting function, but also for mounting hydraulic accessories like grabs, vibrators, etc..
Great care and sturdiness characterize the crane’s most important components, including winches and booms, which are directly designed and manufactured by MAIT.
The crane attachment’s coupling system with the excavator base is patented by MAIT.
