Double Acting Hydraulic Impact Hammers
DAWSON ’ mho roll of Double Acting Hydraulic Impact Hammers is the fastest in the earth, providing blow rates from 120 to 80 blows per infinitesimal at utmost energy. Dawson hammers use hydraulics to lift the crash slant and besides to accelerate the aries down thus provide an increase in impingement supply increased energy and therefore momentum which is the effect that drives the pile. Dawson hammers have a stove of aries weights from 1tonne to 12 tonnes and can be used for driving sheet piles of all sections either in singles or pairs, H-beams and tubes up to 2.6m in diameter. These debauched duplicate acting hammers provide high exercise rates in all conditions ensuring contracts are completed on time .
Excavator Mounted Vibros (EMV)
Dawson ’ second stove of Excavator Mounted Vibros ( EMV ) cover a weight range from 5 tonnes improving to 55 tonnes, using the hydraulic power of the excavator to run the hydraulic motors. Each machine comes with its own base for when not in function and a base hit chain to lift the piles from horizontal to the vertical pitching place to start driving. All machines are easy to maintain and the larger models can drive in pairs of piles. By using a Cassion beam adapter with two jaws you can drive tubes up 1100mm in diameter.
Excavator Mounted Drills (EMD)
Dawson besides make an Excavator Mounted Drills (EMD) that can be easily fitted to the boom of your power shovel perfect for first gear heading board web site conditions or boring over obstructions, the torsion compass from 17.5 to 48.5 kNm and a high might to Weight ratio beggarly that these Drills are very versatile moving around site., where always the excavator goes you can drill a upright hole .
CFA auger cleaner
Dawson ’ s alone CFA auger clean leave spoil from continuous flight augers to be removed at the lowest possible level then as to prevent fishing gear instability and avoid injury to personnel or damage to machinery due to falling debris. Units are custom built to lawsuit customers drilling rigs and auger specifications. An auger clean can be adapted to a variety of unlike auger diameters and pitches using alternative shells. The shell, or barrel, is attached to the bottom of the auger cleaner drive. Auger cleaners provide a flying, mighty and productive means of cleaning all dirt types from a continuous flight auger. This becomes increasingly authoritative as the diameters increase, peculiarly with heavy soils. Models are available to clean plumber’s snake diameters from 300 to 2,000mm, depending on rig specification.
Silent and Vibration less Push-Pull system
Dawson ’ s produce a Silent and Vibration less Push-Pull system that will push or extract piles into the ground, being perfect for inner city areas where shaking and impact hammers can damage surround buildings. Modules can be configured to drive Z, U and H piles either in crane suspended mode or attached to a leader rig arrangement. In simple terms the Push-Pull arrangement works by gripping on some of the for a reaction and driving one at a meter, and then moving to the next voltaic pile and gripping on the rest, in sol doing working backwards and forwards along the fix. It can besides work in reverse to extract mutely .
Universal Pile Extraction machine
Dawson ’ s manufacture a Universal Pile Extraction machine that can extract all sections i.e. Z, U, piles, H beam and besides Tubes out of the ground with either a 400 or 1000 tonnes of power making it a alone machine in the world of piling. This silent excerpt machine has an extraction rate of 3m per min. and is safer than using a vibrator or pulling with a crane.
Dawson Sheet Pile Capping System
The Dawson Sheet Pile Capping System provides a fast economic method of defend shuttering for capping beams on permanent sheet piling works such as River banks, Jetties and anywhere a concrete hood has to be constructed. The labor saving systems hangs off the down wall and is easily assembled and dismantled so it can be moved along the atomic pile wall and support the following section of cap to be constructed. To assess the suitability of the cap organization all we need to be able to specify which is the best set-up to use please provide a draw and leave the rest to us .
Dawson Sheet Pile Threaders
Dawson Sheet Pile Threaders not entirely ensure locate safety but besides enable piles are threaded very cursorily improving work rates and thus saving money. The Universal Sheet Pile Threader will work with all sections of piles such as Z, U and straight sections, making it a universal labor saving device which is very safe. The Standard Sheet Pile bodkin has to be set-up at the beginning to just 1 throng section and therefore is not deoxyadenosine monophosphate compromising as the Universal System .
Sheet Pile Guide Frames
Dawson has supplied Sheet Pile Guide Frames to contractors around the populace to enable sheet piles to be installed accurately and safely when using Vibros and Impact Hammers. Spans of 14 or 26m provide a solid beam at labor level to guide the piles into the footing and a walk way at either 4m or 6m above the flat coat, which has the extra feature of a guard train to provide condom for the operator .
