TYPES OF PILE DRIVING EQUIPMENT

There are serval machine equipment which are employed for pile driving during construction.

Турes of Hammer Pile equipment

• Drop Hammer
• Single acting steam compressor
• Double Acting Pile
• Diesel Pile hammer
• Hydraullic Hammer Pile

Pile Driving Equipment

• Piling Rig
• Piling Winches
• Hanging Leader
• Hammer Guide

1.Piling Rigs

It composed ofaseries of leaders, which are consist of tabular element or hard box, placed and fixed onacrane base as it can be seen on figure. Not only does the leaders support the hammer and the pile but also guide them when the pile is forced into the ground.

2.Piling Winches

The prime goal of piling winches is to left the hammer and piles in addition to support tools that responsible for leader raking and rotation. It functions with pile frames and different powering sources such as hydraulic power, stream; diesel; engines, and occasionally electric motors could be applied for powering or petrol winches

3. Hanging Leaders

Specifically designed to be hanged from the jib ofacrane as shown in Figure-9.Asteel strut, which its length can be varied as per requirements of construction site, providesastiff connection from the leader foot to the machine bed frame.

4.Hammer Guide

In this technique, an independent crane needed to control the pile and establishing the guide and hammer. it is necessary to set and secure the guide properly in order to avoid movements specifically in the during raking pile installation. This is because serious fatigue stress would generate if the thrust is not centered properly and the guide might deteriorate. Finally, disproportionate bending stress development in guide and piles because it leads to undesired it is required to prevent results

5.Piling Hammer

A) Drop Hammer.

• It is a forged steel with solid mass ranges from 1000 to 5000Kg, and it is fitted with lifting eye and lugs for sliding in the leaders.
• Applied to install test piles.
• Its application removes the need to employ steam boiler or air compressor to power the hammer, so it is economical choice

B. Single Acting Steam hammer.

• Consist of massive weight ranges from 2500 to 20000Kg withacylinder shape, and the power source would lift the hammer to specified height then the power is cut to drop the hammer and hit pile helmet. Maximum hammer height is 1.37m and no higher 1.2m in case of heavy pile.

• This suitable for pile installation in marine environnent

6.Piling Hammer

B. Double Acting Steam hammer.

• Double acting pile hammer is powered by steam or compressed and its mass rages from 90 to 2300Kg. Vulcan hammer is an example of double acting hammer. The pile is guided by timber frame.
• It can be used to demolish rocks for extracting piles

C. Diesel Pile hammer.

• It is powered through self-ignition of compressed fuel and air mixture. There are various types of such hammer with different weights ranges from 4500 to 15000Kg. Lastly,
• It is considerably reliable type of hammer and different pile types such as sheet pile, batter pile, and H-beams.
• It properly drives pile in soft soil condition

D. Hydraulic Operated hammer.

• Hydraulic hammer is manufactured in different and large sizes ranges from moderate loading to heavy loading. Hydraulic fluid raises the pile and then release it to fall freely on the pile in addition to have power activated down stroke. Not only can hammer be operated manually but also automatically.
• It suitable for piling in land and in water toa depth of 1000m
