BRUCE SGH-1815 working at foundation construction


The BRUCE, one of the leading manufacturer and supplier in hydraulic hammer industry in a worldwide range, is working on PHC Piles at a foundation construction site to erect a skyscraper.

Interesting is this, Isaac Newton, an English physicist and mathematician, who is widely regarded as one of the most influential scientists  of all times until so far today.

The BRUCE must be in respect for him and his scientific formula such as ‘Laws of motion’ & ‘Universal gravitation’ that his theory is still descripted by the hammer and remained practical.

This is because the BRUCE hydraulic impact hammer is utilizing such a formula along with ‘Law of mass conservation’ or gravitational energy while driving the piles in an actual circumstances.

Following to the formula of ‘ potential energy’ which is explicable as W = m. g. h means that

a certain mass or fluid would have a certain energy when it is being rising at h height,

the BRUCE hydraulic hammer in the end well performs at this optimal formula by eliminating the

possible factors having a bad influence to a hammer operation, for instances, loss of pressure,

Inefficient power delivery, the occurrence of friction force in the cylinder and buckling in the rod.

The free falling Ram, particularly, carries out its principle very well without any of influential load.

The BRUCE hammer SGH-1815 with a maximum potential impact energy of 27 ton.m and blow rate of 28 bpm powered by hydraulic power pack PQ-500 with 623 hp of engine power had performed really well and reached to the customer’s complete satisfaction. 

Driven pile length were 50 meters in total to drive to be finished, therefore, each 12 meters of PHC piles were connected consecutively by welding on a black colored steel cap place.

The first stage of pile driving work was progressed in a somewhat soft soil condition.

In preparation for this case that may cause hammer a sudden downfall to the ground,

the BRUCE SGH-1815 hammer can be controlled by an flow adjuster to move slow for this work

Assembly and installation of BRUCE SGH-1815 hammer

For the project, the BRUCE SGH-1815 hammer was attached with a six pieces of Guide Claws

on the Fixe Leader Type of a pile driving rig equipped with a special made Lifting Sheave.

A six pieces of Guide Claws, which was specially made to fit into pile driving rig for this time  will make sure pile driving work to become an straight line and driven all the time without waving or shacking the piles while the hammer is sliding the Leader upwards and downwards

Assembly and installation of BRUCE hammer was proceeded by an typical procedure of hammer assembly following to BRUCE’s long years of experience to handle with equipment settling down them in a short time, promptly and rapidly, including at the same time hydraulic pressure and related sensors.
A piece of equipment the BRUCE hammer SGH-1815 and power pack PQ-500 had finished assembly and installation altogether with hose bundles, electrical cables and sensors for monitoring no functional failure are proofed, before just starting the job.

A complete match with PHC Pile by BRUCE SGH-1815 


The potential energy in at 27 tons with a maximum stroke of 1.5 meters the BRUCE hammer carried out a high energy transfer into the PHC piles that dominates a 90% of concrete pile productions worldwide through the era of RC pile in the year 1970 and PC pile until early 1990.

The PHC piles can be specified its specification according to the outside diameter and driving piles should possess a valid free stress for the head of pile part to transfer an adequate energy

to the ground in a safe mode within the level of satisfactorily calculation of a bearing capacity.   

There will be nothing to cope with the PHC piles except BRUCE hammer.

Big attentions to the advantages of BRUCE hammer

Most of the builders or operators on job sites may happen to meet an unexpected obstacles blocking the dead line of their planned project schedule to be postponed or even failed.

To meet the scheduled construction duration, there needs consideration about a bunch of practical factors to make work done successfully within the time.

These are might fall on that you are worry and want to eliminate in advance before work started.

For instances, estimation of pile’s bearing capacity divided into allowable and ultimate, pile’s

deformation in plasticity and elasticity, soil’s deformation in elasticity and friction force in the vicinity of driving piles and rapidity and accuracy to complete a given upcoming project.

The BRUCE will be a ingenious solution for you exactly !
