Description:

Komatsu Rigid Dump Trucks 730E 7 16 Cylinders Diesel Engine

Dump Trucks r loaders are used for loading and carrying. The application is not limited to civil engineering but they are serviceable in a wide range of work like solid waste management in narrow lanes and garbage dumps, livestock, farming and gardening. Moreover, by replacing the bucket with a fork, they can also serve as a material- handling machine.
