Types of Diesel Hammer DD Series and Their Applications in Construction

Series Diesel Hammer

A diesel hammer is a pile driving machine that uses energy generated from diesel fuel combustion to produce powerful impact force for driving piles into the ground.

In modern construction, diesel hammers are widely used because they are:

• powerful

• efficient

• independent from electrical power

One of the commonly used solutions in the field is the Kangding diesel hammer, especially the DD series, which offers various sizes to match different project requirements.

General Types of Diesel Hammer

Before discussing the DD series, it is important to understand the basic types:

1. Single Acting Diesel Hammer

• Operates using free fall + combustion

• Simple structure

• Easier maintenance

• Most commonly used in construction projects

2. Double Acting Diesel Hammer

• Uses additional force during upward and downward motion

• Higher striking frequency

• More complex and less commonly used

Diesel Hammer DD Series (Most Widely Used)

The DD Series diesel hammer is categorized based on impact energy and machine size.

This series is suitable for a wide range of projects, from light to heavy construction.
