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.
