SHACKLES

Mobile cranes, ideal for indoor use. The mobile jib crane can lift loads ranging from 150 kg to 500 kg with a radius of action of around two metres. The mobile jib crane can be moved by means of all-terrain wheels, which allow it to move on any type of ground. The most commonly used model is the mobile jib crane with a triangular boom with a hollow profile that adapts to workshop conditions.

Drum cranes are the most common cranes, especially in the industrial sector. This type of crane is designed to move very heavy loads of up to several tonnes. They can be used for both indoor and outdoor applications. The jib crane is fixed with chemical anchors or with anchor rods and concrete blocks. The jib cranes are available with a triangular or inverted jib with a rotation range of 270° to 360° and a reach of up to 9 metres.

The wall-mounted jib cranes are equipped with a triangular or inverted jib, which reduces the headroom. The wall-mounted jib crane has the option of being motorised or manual with a 180° rotation. The wall-mounted jib cranes are suitable for individual use and avoid clutter in the work area. The lifting capacity of this type of jib crane ranges from 150kg to 4 tonnes with a standard reach of up to 8000mm.

To choose the right jib crane for your lifting application, you need to:

Shackles are made from a bracket and are usually closed by a movable pin which is screwed on with a bolt-nut or a screw. These lifting accessories can be attached either directly to the load or with a rope, chain or sling. Shackles are generally used in construction, forestry, public works or marine activities.

Levagemanutention.com offers several types of shackles of different sizes and shapes to suit all your operations. Each shackle is CE certified and carries a brand mark.
There are straight shackles and lyres shackles. Lyres shackles have a more rounded shape with more space inside than a straight shackle. There are also heavy duty shackles with a nut bolt or shackles with a screw. The shackle screw is fixed directly into the shackle, whereas a nut bolt is inserted into the shackle and fixed with a nut.

We recommend that you check regularly to ensure the safety of you and your load. Be sure to check the eye and pin hole of the shackles for signs of stretching or wear, which would indicate overloading. Check that the shackle body is not bent due to excessive oblique tension. The shackle pin should not show corrosion, distortion or signs of wear. If this is not the case, the shackle is no longer functional. All shackles showing defects or signs of wear must be replaced.

When using a lifting shackle, it is important to know the right things to do to avoid easy wear and tear and to ensure your safety. First of all, never replace with a different bolt or pin, as the shackle pin may break under the weight of the load because it is not fully adequate. You should not allow any oblique tensions that could affect the capacity of the shackle, so we recommend placing washers on the pin to centre the hook. Be careful not to force the shackle into position with a hammer or wedge. Finally, do not arrange the strands of a sling so that there is an angle greater than 120°.
