SGH-4719 The Largest Hammer Ever In US History


The biggest hydraulic hammer utilized at New Sakonnet River bridge, USA

The replacement of the Sakonnet River Bridge, which carries nearly 40,000 cars per day and provides a critical transportation system link between Massachusetts and Rhode Island, is necessary to meet current highway design standards for shoulder width and structural capacity.

A, 3,160-ft-long, 4-lane bridge will be built along an alignment located immediately south of the existing bridge, which will remain in operation during construction.
Standing where the new bridge will soar overhead, State officer Carcieri and other officials marked a milestone in the long process to replace the 53-year-old bridge. Construction work under way and is projected to open to Route 24 traffic in spring 2012.

It is extraordinarily important to towns on both sides of the span.
The project will replace the old span with one directly to the south.
The new bridge will include a 13-foot sidewalk for pedestrians and bicyclists, a passage underneath for boats more than twice as wide, and a boat ramp on the Tiverton side. More importantly for motorists, the new bridge would end a detour of up to 30 miles for trucks heavier than 18 tons.
The weight restriction also kept fire trucks in Portsmouth and Tiverton from helping in emergencies in each other’s communities.

It is the most expensive bridge project in state history and is projected to create up to 140 construction jobs and 330 indirect jobs, according to RIDOT.
“We need the jobs,” Carcieri said. It will be built by Warwick, R.I., company Cardi Corp., which is also building the Providence River Bridge, which carries Interstate 195.


Decorative features of the bridge have been preserved, however.
LED lights — which according to renderings will be red, blue or green — will highlight the bridge’ s piers in the river, and red lights will be attached vertically to light posts that line the center median.
The new bridge will be 65 feet, the same height as the current span. The new bridge is expected to open in 2012.

Community benefits ;
* Improved public safety and seismic protection
* Increased transportation capacity for existing and future traffic volumes
* Added bicycle and pedestrian path, separated from vehicular traffic by safety rails
* Replacement bridge alternative minimizes the cumulative impacts to the environment


BRUCE SGH-4719 Hydraulic Hammer accomplished 72 inch Casing Pile job

A major US contractor of this project used BRUCE SGH-4719 Hydraulic Hammer featured with 89.3 tom.m (876 kJ) of maximum potential energy,1.9 meter (6.23 feet) of maximum stroke and is powered by 1100 HP (820 kW) capacity of power pack model PQ-1200 for the first time since in the US bridge construction history, specializes in marine and general construction, marine equipment rental and sales to include ABS and inland barges.

The Company has both the expertise and the equipment to provide the highest levels of services and products available in the marine industry.
This project was located in Tiverton, Rhode Island, USA.

This heavy and marine construction project involved pile driving of 72 inch diameter and 200 feet long (join 150 ft + 50 ft) steel casing piles for foundation support for bridge structures, with retaining the ground shake along the new Sakonnet River Bridge retaining more increased span on both side of the bridge for the future transportation volume.

The entire pile driving operation was controlled by the smart and sophisticated Remote Control Box ensuring the electrical and hydraulic movements to be seen by operator’s visual check.
