Page 6: Introduction & Features
www.dcpuk.com introduction This robust pile lifting shackle was designed and developed over many years of site use and abuse. The use of these shackles compliments the “Feet on the Ground” approach to steel erection and pile installation. When used in conjunction with the Sheet Pile Threader, there is no need for site operatives to go above the safety of top frame level for interlocking sheet piles or releasing the lifting shackles.
Page 7: Method Of Operation
method of operation 1. Tie a length of soft rope to the pull ring on the pull wire. The rope should be 1 metre (3 feet) longer than the pile length. Do not use a continuous loop as this will become snagged. 2.

Page 22 The Pull Wire may require changing if it is frayed, kinked or generally damaged. First remove the guide key. Unscrew the M6 cap head screw and washer. The guide key can now be retracted. Remove the plug from the underside of the shackle body.
Page 23 Remove the 4 No. M8 cap head screws holding the tube assembly to the shackle body. Carefully retract the assembly from the body as shown. The sleeve is attached to the plunger via a coiled pin. This needs to be removed.
Page 24 Drive the coiled pin out using a 5mm punch. REMEMBER TO WEAR EYE PROTECTION! With the sleeve removed the old Pull Wire can be extracted. IMPORTANT: The new Pull Wire tail must be threaded through the largest ring to ensure correct orientation at final assembly.
Page 25 The sleeve can now be replaced and coiled pin hammered back in place. A new coiled pin may be required if the old one is damaged. IMPORTANT: Ensure the coiled pin is flush on both sides of the sleeve, this will allow smooth operation in the shackle body.
Page 26 Finally check correct operation of the mechanism. Gloves should be worn for these operations! First operate the Pull Wire to retract the plunger. This requires reasonable force. The plunger should remain in the retracted position. A tap with a soft hammer should fire the plunger forward.
