Our supplier Dawson Construction Plant UK, have developed the 100TLifting Shackle that are hydraulically remote operated. This project was the first time use of the 100T shackles worldwide.
The photos show the shackles being used to lift a tube pile of approximately 90-100T which is just in excess of the capability of a pair of Dawson 40t Ratchet Release Shackles.
Although the shackles weight 410 kgs each, they can be handled with ease by 4 lifting points to engage it onto the tube in the correct horizontal position at 180 degrees opposite, the hydraulic pump then engages the pins through the tube wall so they are fully engaged by using a spreader beam between the shackles and the crane line, allows the lift to commence, once vertical and in position no doubt many metres above ground level, the pins are then extracted hydraulically to release the tube and complete the lift.
Work completed: The ICE 55NF was used to drive 18 no. bridge foundation piles, being 15m long and 1,200mm OD each, required for the erection of a new multi-lane traffic bridge to replace the existing 100 year old bridge. The piles were driven into a river bed consisting of gravels and sands overlaying stiff clays.
Location: Sydney, NSW
Work completed: The ICE 44B vibratory hammer was used to drive a large 2,400mm pile casing around the existing (but not completed) structure.
Location: Shellharbour, NSW
Project: Pilequip’s ICE 14-23c high frequency vibratory hammer used to extract a sheet pile wall (approx. 600m long), consisting of PU double sheet piles. The piles ranged from 8m to 17m in length.
Project: Fitzgerald Bridge
Work completed: A HHK7/9S was used to drive 762mm OD piles for a new bridge in Aberdeen.
Project: Marine Supply Base,
Location: East Arm, Darwin
Work completed: Pilequip’s ICE 58B Vibratory Hammers were used to drive 1,400mm, 1,150mm and 1,200mm OD piles into position, until refusal. Our Junttan HHK14/16S and another client’s Junttan HHK25S Hydraulic Impact Hammers used to drive the piles to final set.
Project: AP LNG
Location: Gladstone, QLD
Work completed: Pilequip’s Junttan HHK25SB was hired and operated by a specialist subcontractor and used to drive 1,500 and 1,200mm OD piles at the AP LNG project at Curtis Island, Gladstone.
Project: Gorgon LNG Plant
Location: WA Coast Line near Onslow
Work completed: Our client hired Pilequip’s Junttan HHK18/20S hammer to drive tubular cyclone moorings, as specified for the marine plant & equipment working on the Gorgon LNG Plant project. The piling work consisted of 23 no. 1,350mm OD piles.
Project: GLNG Train Through Foundations
Location: Gladstone, QLD
Work completed: Our client was responsible for the construction of the Train Through Foundations for the Curtis LNG plant on Curtis Island near Gladstone. The Train Through Foundations consisted of more than 400 piles. Pile casings of 600mm and 1,050mm OD size were driven using Pilequip’s ICE 44B Vibratory Hammer. The casings were later drilled out with a piling rig and filled with concrete. The casings were then extracted with Pilequip’s ICE 44B whilst the concrete was “wet”.
