Lifting Equipment

LIfting Loops

EKC lifting loops are manufactured from wire rope held in a steel ferrule to which a standard isometric external thread is added, to mate with the steel sockets or inserts.

Each lifting loop is tested to twice its working load and is certified. Steel tags on the loops indicate the safe working load and carry the loops individual serial number. All loops supplied comply with “The Supply of Machinery (Safety) Regulations" – 1st January 1995.

Lifting Inserts

The cast-in insert provides an alternative to the lifting socket. It is made from tube that is threaded internally at one end and flattened with a cross-drilled hole at the other end to accept the reinforcing bar. They are available in both stainless steel and zinc plated steel to offer some protection against corrosion. Normally supplied without plastic sealing caps but these are available to order.

Lifting Sockets

The system comprises a cast-in lifting socket, which is drilled laterally below the threaded portion in order to take a reinforcing bar that is located and tied to the main reinforcement to provide the user with a positive and secure anchorage point. They are available in both stainless steel and zinc plated steel to offer some protection against corrosion. Each socket can be supplied with two plastic inserts. The upper one (optional extra) is used to prevent ingress of dirt into the threads whilst the lower one (standard) is used to prevent ingress of concrete during the casting process.

Wavy Tail Anchors

The Wavy Tail Socket Inserts are complete reinforced anchors for installation into precast units of all sizes e.g. Safety barriers. The unique design of the reinforcing tail safely transmits the tensile forces into the concrete, alleviating the need for additional reinforcement.

All units can be supplied complete with a plastic cap (optional extra) to prevent contamination of the socket thread.

Fixing Inserts

Fixing inserts provide a simple and competitive fixing in concrete. Supplied with a flattened end cross-drilled to accept a reinforcing bar.

It is essential to screw the bolt over the full ‘thread length’. The safe working loads of the fixing insert can be increased by adding formed rebar of sufficient length.

Care should be taken when inserts are placed close to the edge of concrete or in groups as their loading capacity is reduced. This also applies when the insert is in a recessed position. Installation guidelines can be obtained from the EKC Engineering section.

Bent Tail Fixing Inserts

Fixing inserts provide a simple and competitive fixing in concrete. Supplied with a flattened end bent through 90 degrees.

The recommended safe working loads are obtained by applying a safety factor of 4.5 to the average pullout load of inserts in 22.5N/mm² concrete. These inserts are for fixing only and are not recommended for lifting or high load applications.

Spherical Head Lifting Shackles

The spherical head-lifting shackle is used with the spherical head lifting pins. Even under load, movement is possible in 3 axis and if correctly fitted accidental uncoupling is impossible.

These come in a range of sizes, with the size of shackle you require being determined by the size of spherical pin cast into the unit.

Spherical Head Anchors

Made of special steel with guaranteed notch impact strength and highly resistant to brittle failure. Available in a large range of sizes from 1.3 ton to 32 ton with a varied selection of lengths to suit customer applications.

The recommended safe working loads are obtained by applying a safety factor of 3 to the average pullout load of spherical head anchors in 22.5N/mm² concrete.

Rubber Former - Round

Complete with fixing plate and attached bolt with wing nut this provides a void for insertion of the lifting shackle.

Ring Clutches

The Ring Clutch system is used with the spread anchors. Similar to the shackles even under load, movement is possible in 2 axis and if correctly fitted uncoupling is impossible.

These also come in a range of sizes and again this is determined by the size of anchor that is cast into the unit.

Spread Anchors

A 2 dimensional lifter with the stress transfer to the concrete occuring through the reinforcement bar and the lower spread of the anchor.
