BRUCE hammer SGH-1415 working at bridge construction  

<CRANE SUSPENDED WITH A U-TYPE LEAD FOR BETTER ACCURATE PILING JOBS>

 

For the project, the BRUCE hammer was operated attached with a U-Type Lead by a crane.

The bottom part of U-Type Lead was equipping a specially made Pile Guide to operate, make this hammer much more accurate, stable and economical option for driving such concrete piles ensuring an straight lined pile driven all the time without waving or shacking the piles. 

The U-Type Lead suspended by a crane took also important role to let the hammer hold firmly in a squared box shaped lead to do a regular pile driving work moving ups and downs.
 

The BRUCE hammer SGH-1415 was available with this U-Type Lead structure that was just fitted for a squared concrete pile for use as freely suspended for operating from a crane. 
 

The scope of work included the driving of concrete piles was associated foundation work which will enable the bridge structure with increased bearing capacity, thereafter, enhancing the efficiency of the bridge link to the next section or neighboring road.
 

The BRUCE hammer supplied complete with 30 meters of Hose bundles, U-Type Lead with Pile Guide, a squared Pile Cap and hydraulic power pack PQ-300 that was operated by a Remote Control Box. The BRUCE hammer, despite the remote situation the hammer was installed.
 

did carry out a superb performance on site so as to utilize the hammer for long.    

Assembly and installation of SGH-1415 hammer

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. As long as the key factors having an effect to hammer operation had not changed under the customer approval as tested BRUCE’s factory, the hammer was ready to go next step like testing piles or moving it directly to job sites according to its working situation.

A piece of equipment the BRUCE hammer SGH-1415 and power pack PQ-300 had finished assembly and installing hose bundles, electrical cables including all sensors for continuous Monitoring and no functional failure are proofed, before going to the job site

Testing piles has conducted before going to the job site 

The BRUCE hammer SGH-1415 had conducted a test piling with couple of squared concrete piles together with a crowd of customer gatherings to check the hammer can handle in access  ultimate bearing capacity and potential energy in at 21 tons with a maximum stroke of 1.5 meters.
 

The BRUCE hammer carried out a high energy transfer into piles up to 90 percent and could operate without loss of energy according to the test result instrumented by IEA system.  

The BRUCE hammer is free falling hammer utilizing the principle of impact atomization.
 

This hammer has been designed and focused on eliminating the energy loss for the utmost important approach to its design fabrication when a cylinder up and down movement by controlling the pressure

BRUCE Hydraulic power pack PQ-300

Brief specification of SGH-1415 hammer and power pack PQ-300 are as follows. 

          

 

Impact Energy monitored on a real time basis

The trial was also being used to test the IEA (Impact Energy Analyzer) of a proper impact energy

output retaining and displaying on the IEA monitor that  was originally designed for the concrete piles on a real time basis as well as the hammer not to break the piles during its operation. 

 More than anything else, the most attractive merit of using the IEA system is accounted for enabling the field crews to take immediate action even far from a distance

It is an excellent way of protecting both pile materials and hammer equipment itself.

Energy Monitor system was utilized for BRUCE SGH-1415

The IEA is essential for a driven pile foundation to estimate hammer energy efficiency at a real time basis of the driven pile working. it is also possible to adjust IEA system to fit adequate stroke height without checking the making line on the hammer.

The IEA system will give the engineer the option of determining the penetration depth for a single pile and it assesses hammer energy capacity, cumulative blows, blow rates etc, at a real time data interpretation. When the engineer is present on site by the IEA system, it displays all the job data and results, therefore, a field crew can evaluate the data such as blows per step, blow rate and energy per step through it.

Advantages of IEA system

Window touch screen of monitor display

Up to date, robust, and easy to use.

Design and construction of driven pile foundation.

Actual Stroke Height adjustment without checking marking line on the hammer.

Analysis of an average hammer energy on Penetration Depth by step.

Blow rates at each steps and whole steps for a single pile.

Unlimited job data storage for the next time working schedule.

A total pilling time of a single pile for set up a construction plan. 

A real time basis of job data by selecting the operation mode.

Easy conversion the Engineering Unit for customer convenience.

Pile history management and a job proof to be presented.

Job data printing out for an immediate interpretation on site.

Compatible with Widows and evaluation data at the office.
