TEXTILE ROUND SLINGS
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:
Know the environment in which you want to install your jib crane. This will allow you to choose between a fixed jib crane, a mobile jib crane or a wall-mounted jib crane.
Know the load you wish to lift with the crane. The weight will allow you to choose the necessary lifting capacity.
Know the maximum height and reach required to lift the load.
Know the type of jib crane you want : you can choose between an electric jib crane or a manual jib crane.
A design office is at your disposal to meet your lifting needs for your cranes and gantries. The design office will draw up an estimate according to your request. For further information, please contact our customer service.
What is a textile round sling?
Textile round slings consist of a core (one or more threads wound together to form an endless skein). This skein is inserted into a sheath of the same base material as the core. Round slings are suitable for lifting cylindrical or rounded loads such as steel pipes or boats. Round slings have the special feature of being sewn together to fold back on themselves to create endless round slings. These slings have the particularity of having a low weight which makes them easy to handle and transport.
How to identify round slings ?
Round textile slings can be identified by means of a label sewn onto the sling's sheath. The label has a visible part and a hidden part in the overlap of the sheath. The sling label identifies the main characteristics of the lifting and handling sling.
First of all, the colour of the label indicates the textile material used to manufacture the sling: green indicates that it is a polyamide sling, blue for a sling made of polyester and brown for a sling made of polypropylene. On the visible part of the label, you should find elements that are essential for identifying the sling :
- The maximum working load (WLL) in tonnes or kilograms and the corresponding angle range for multi-strand slings.
- The material used to create the round sling
- The class of the accessories (buckles...)
- The nominal length of the flat webbing sling in metres
- The name or symbol of the manufacturer
- The tracability code, which identifies the basic manufacturing elements such as the identification of the sling, the manufacturer's control and the accessories
- The number of the harmonised standard
- Mandatory CE marking
Like all textile slings, round slings can be identified by the colour of the strap corresponding to the associated load capacity. Thus, 1 ton round slings are purple, green corresponds to 2 ton slings, yellow to 3 ton slings, grey to 4 ton slings, red to 5 ton slings, brown to 6 ton slings, blue to 8 ton slings and finally orange to all textile round slings over 10 ton.
Checking your textile
In order to carry out a slinging operation in complete safety, it is advisable to carry out a daily visual inspection of the round textile slings. If you notice any of the following during your inspection, the sling should be removed from service.
- Please do not use your sling if you notice any local deterioration of the strap, distinct from general wear and tear, as this could lead to an accident.
- If you detect a transverse or longitudinal cut, damage to the edges by cutting or heating, or a cut in the seams, then it is not suitable for use.
- If your round textile sling suffers a chemical attack which causes a weakening or softening of the material; this is distinguished by the flaking of the surface of the sheath which can be torn off or removed by friction, then it must be taken out of service.
- Similarly, if your sling suffers heat or friction damage, which is indicated by the satin appearance that the fibres may take on, or in extreme cases, by the appearance of a "hard spot" inside the round sling sheath.
- If the fittings are deformed at the ends, you can have your fitting checked and repaired by an expert organisation.
- Finally, if your sling does not have an identification label attached to the sheath, it is unusable because it does not comply with the laws in force.
For round textile slings, there is a process, thanks to the wear threads woven under the weft, which shows the wear of your sling.
You may also note that textile slings are sensitive to sunlight and ultraviolet rays which cause deterioration of the material. Therefore, round slings that are often exposed to the sun should be checked more regularly. Slings can sometimes become brittle without any deterioration or change in appearance. In each case, the information in the manufacturer's instructions should be taken into account in order to determine the service life of your sling.
