We can supply the following types:

REMOTE GROUND RELEASE LIFTING SHACKLE

This robust pile lifting shackle was contractor designed and developed over many years of site use and abuse. The use of these shackles compliments the “Feet on the Ground” approach to piling.

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. The shackles are suitable for lifting all steel piles up to 28mm thick and within the safe working load of the shackle. The shackle is stiffened to resist spreading of the forks when lifting at 90° to the axis of the pile. (See “Safety Check List”). When lifting sheet piles in pairs or individual piles weighing more than the Safe Working Load of the shackle, it is necessary to use multiple shackles in order to keep within the safe working load.

Pairs of shackles can be supplied mounted on a two legged steel wire rope sling. The advantage
being that the standard pair of shackles with lifting sling can be fitted to any pair of Larssen ‘U’ piles, Frodingham ‘Z’ piles, pipe or box piles. No additional parts or change of components is necessary.

The ring at the top of the sling can be hooked directly onto a standard crane hook block, ‘D’ shackle or fork anchor. Shackles can also be fitted onto a solid steel cross head according to customers requirements.

FEATURES

. Robust High Strength cast steel body. High alloy steel plunger.
. Plunger mechanism concealed for maximum protection.
. Plunger mechanism easily detachable for maintenance.
. Heavy web stiffening to withstand side left (i.e. 90° to the axis) imposed when lifting piles from a stack. (See “Safety Check List” for correct working practice).
. Lifting ring at top of shackle to enable lifting from a variety of angles.
. Proof loading to twice the safe working load.
. Indicator bar to give clear visual indication that plunger has engaged pile lifting hole completely.
. Shackle throat depth available in two sizes: 150mm (6”) or 250mm (10”) to suit all usual lifting hole positions.
. Quick coupling and release of shackle from piles ensuring maximum productivity.
. ‘Safety ring’ to protect against accidental plunger release caused by poor working practices.

REMOTE RATCHET RELEASE LIFTING SHACKLE

This robust lifting shackle was contractor 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.

There is no need for site operatives to go into a dangerous position to release the lifting attachment.
The shackle is stiffened to resist spreading of the forks when lifting at 90° to the axis of the lift

(see “Safety Check List”).

The Ratchet Shackle is designed for lifting steel through standard bolt holes or other units of lift having a suitable hole through which the pin can be conveniently and safely engaged.

FEATURES

Robust high strength cast steel body.

Pin mechanism concealed for maximum protection.

Pin mechanism easily detachable for maintenance.

Can be used for lifting columns, pipe piles, sheet piles & steel fabrications.

Heavy web stiffening to withstand side lift (i.e. 90° to the axis) imposed when lifting from the horizontal. (See “Safety Check List” for correct working practice).

Independently proof load tested to twice Safe Working Load. Test certificates are supplied with each shackle.

Super safe design which avoids accidental release.

Positive pin release at the proper time.
