Question

With neat sketches, explain any two methods of earthmoving

Answer 1

1. Excavators

Excavators can be utilised over wheels or treads and are used most often to shovel dirt or lift heavy pieces of machinery. They are usually obvious on account of their long bucket arm attached to a cab which pivots. Excavators are operated by a worker who, in the cab, has high visibility over the work area



2. Backhoe Loaders

Backhoe loaders are mounted on tires and can be used in suburban areas. They share many similarities with tractors. The main difference is they contain a shovel at the front which can be adjusted and a bucket at the rear which is used to dig. Backhoe loaders are usually the best choice for smaller jobs which need to be completed in a more restrained space. Backhoe loaders shift dirt, shovel trenches and position pipes into place.
