Crane hooks
Crane hooks are reliable and robust connecting elements that can be used in various applications. They are used to lift and transport heavy loads safely and securely. The high load bearing capacity and various sizes and designs offers a flexible solution for different requirements.

Frequently asked questions about crane hooks
What are crane hooks?
Crane hooks are hoist and carrying aids which in machine and plant construction provide a secure connection between a crane, hoist equipment or lifting tackle and the°load to be transported°. They are attached to chains, ropes or round slings and transfer the load directly to the hoist equipment.
Load hooks are categorised by grade. The grade indicates how much weight a hook can bear based on its own specific weight. A higher grade indicates greater strength and, consequently, a higher permissible load for the same amount of material used.
Crane hooks are used wherever loads need to be securely slung and moved in manufacturing and in warehouse logistics. They are also used for internal transport with forklift trucks or hand pallet trucks, as well as for lifting with cranes and other hoist equipment.
Design and function of crane hooks
A crane hook consists of several components which together ensure that the load is secured safely.
Hook body:°It bears the load and transfers the force to the sling. The form and cross-section determine how much weight the hook can bear.
Slip hooks with eye: The eye on these hooks serve as a connection point for chains, ropes or slings and enables a secure connection.
Safety latch: This prevents the load from becoming accidentally dislodged from the hook and is an important safety feature, particularly with changing loads.
Surface finish: A zinc or plastic coated surface protects the hook from corrosion and extends its service life.
Material:°Crane hooks are usually made from high-strength steel treated to meet a specific grade.
At°norelem°, crane hooks are only available in combinations that are carefully matched to one another. In the online shop the products can be filtered according to permissible load, chain size and grade, so that the suitable model can be quickly found without losing overall perspective.
Crane hooks from°norelem: types and grades
The°norelem°range includes°Grade10 slip hooks°in various versions. These include°slip hooks with°an eye(Form A)°and slip hooks with a clevis (Form B) and supplementary slinging aids such as°carabiner clips,°swivel hooks°and°connecting links.
Grade 10 is characterised by particularly high strength. Compared with Grade 8, higher loads can be managed safely whilst the hook has the same specific weight. This makes hooks°with this grade the standard choice for professional use in machine and plant construction.
In addition,°norelem°distinguishes between standard crane hooks and°safety crane hooks. Simple crane hooks have an open design and are suitable for applications with permanently fixated slinging points. Safety crane hooks are fitted with a safety latch, which prevents the load from coming loose during transport. They are recommended where loads are changed frequently or when people are present near the lifting operation.
Slip hooks with an°eye°(Form A) are connected directly to chains or eyes and are suitable for fixed slinging points. Slip hooks with a clevis (Form B) enable flexible and often revolving connection, e.g. when a rotator is used or the load needs to be turned regularly. For permanent mounting e.g. on the forks of forklift trucks,°norelem°also supplies crane hooks designed to be bolted on.
Round sling hooks
Round sling hooks°are specially designed for use with°round slings°and°lifting slings. Its wide contact surface protects the lifting tackle and prevents stresses that could lead to premature wear.
The°norelem°range includes various types of round sling hook, with and without safety latches, and with different permissible loads. This enables the correct combination of hook size and load capacity to be found for every application.
Selection criteria: Finding the right crane hook from°norelem
The choice of crane hook for a particular application depends primarily on the lifting tackle used, the required permissible load and the operating environment. For applications with chains, slip hooks with an eye are recommended; for flexible or rotating movements types with a clevis or swivel hook are more suitable.
In machine and plant construction, crane hooks with a high permissible load are frequently used, whereas in warehouse logistics, smaller and more compact designs are sufficient. For specific applications,°norelem°provides suitable products in its online shop along with further information.
One of the key technical features is permissible load. At°norelem°, the range includes light models for up to 50 kg up to crane hooks with permissible loads of up to 10,000 kg. The range therefore covers both light applications and heavy lifting applications.
Temperature also affects the permissible load. As the ambient temperature rises, the maximum permissible load decreases. This is particularly important to bear in mind when working in areas where heat builds up.
For materials and finishes,°norelem°opts for high-strength steel with a galvanised finish to ensure reliable protection against corrosion. On some models, the safety latch is also plastic-coated to protect the sling from damage. Manufacture is carried out in accordance with the standard safety requirements for professional lifting operations.
Frequently asked questions about crane hooks
What are the advantages of crane hooks for forklift trucks?
Crane hooks enable loads to be secured quickly and safely to the fork arms or the lift mast. This means that e.g. round slings, chains or lifting tackle can be used flexibly without the need for additional equipment.
What are the advantages of crane hooks?
Crane hooks are robust, versatile and enable rapid slinging of loads. The wide range of designs available mean they can be tailored precisely to different applications and permissible loads.
What crane of load hooks are there?
Common types include slip hooks with an eye, slip hooks with a clevis, self-locking hooks, round sling hooks, carabiner clips and swivel hooks. Each version is designed for a specific purpose.
What are crane hooks suitable for?
Crane hooks are suitable for the safe slinging and movement of loads in machine and plant construction, in warehouse logistics and for general lifting operations using cranes or other lifting equipment.
What are crane hooks used for?
They connect the lifting gear to the°load to be transported°and, in doing so, handle the actual transmission of force. Without a suitable crane hook, a load cannot be safely rigged.
Can hooks without a safety latch be used?
Open hooks without a safety latch are suitable for applications with permanently fixed slinging points where there is no risk of the hook becoming disengaged accidentally. By varying loads or movements however, a hook with a safety latch should be used.
Do all hooks fit into every°lashing eyelet?
No. The size of the hook must match the eyelet or slinging point. When making a selection, one should therefore always check that the dimensions of the hook and the lashing eyelet match.
