Backhoe Loader 388H(4TX)

Product Introduction

Backhoe loader is a single device that consists of three pieces of construction equipment. It is commonly known as "two-headed". During construction, the operator can switch the working end by simply turning the seat. The main work of a backhoe loader is to dig trenches to lay pipes and underground cables, lay foundations for buildings and establish drainage systems.

 

The main reason why backhoe loaders appear on all construction sites is that various projects require digging and moving soil. Backhoe loaders should be compact and can be moved around various construction sites and even run on roads. Contractors need to carry out both excavation and loading operations, and using backhoe loaders can save a lot of time and money.
