Yale ASHS Weld-On Hook (Heavy Duty)

3000kg to 8000kg WLL | Forged Steel Weld-On Hook | Stainless Steel Return Spring | Epoxy Resin Coated | Fully Traceable | CE Marked

The Yale ASHS heavy-duty weld-on hook is a universal lifting attachment for welding to trucks, excavators, low loaders, big bag frames, spreader beams and lifting frames. The hook and forged safety latch are epoxy resin coated for added corrosion protection, with a stainless steel return spring. Every weld-on hook carries an identification number so its history can be traced back through forging to the origin of the material — meeting the stringent traceability requirements of modern lifting equipment standards.

Key Features

• Forged steel construction for high-strength, repeatable performance under lifting loads.
• Forged safety latch with high lateral stability and ergonomic shape for reliable load retention.
• Stainless steel return spring for long service life in outdoor and corrosive environments.
• Epoxy resin coating on the hook and safety latch for added corrosion protection.
• No weld preparation required — hooks can be welded without pre-warming, simplifying installation.
• Three capacity options from 3000kg to 8000kg for heavy-duty lifting applications.
• Identification number on every hook for full traceability through forging to material origin.
• Certified and documented — supplied with UKCA / CE marking and certification.

Technical Specifications

Refer to the Yale ASH datasheet for full dimensional data (overall height, hook opening, throat depth, weld preparation requirements). All ASHS hooks are forged from drop-forged alloy steel and supplied with a forged safety latch and stainless steel return spring.

Suitable Applications

The ASHS heavy-duty weld-on hook is ideal as a permanent or semi-permanent lifting attachment point on trucks, excavators, plant equipment, low loaders, big bag lifting frames, spreader beams, custom lifting devices, and recovery vehicles. Heavier than the standard ASH range — the 3000kg, 5000kg and 8000kg ASHS variants are designed for industrial and heavy plant applications.

How to Use the ASHS Weld-On Hook

1. Inspect the hook before welding. Check the body, hook opening, safety latch and return spring for damage. Do not use if defects are found.
2. Select a suitable mounting position on the host structure. The host material must be of weldable quality and rated to carry the load applied through the hook.
3. Weld the hook to the host structure in accordance with the hook manufacturer's instructions and applicable welding standards. No pre-warming is required for the ASHS weld-on hook itself, but consider the host material's requirements.
4. Inspect the completed weld for full penetration, absence of cracks, and correct fillet size. The weld must be capable of carrying the rated WLL.
5. Have a competent person proof-load test the welded hook before placing it into service, as required by the design of the lifting equipment it forms part of.
6. In use, ensure the load is attached via a suitable sling, shackle or attachment with the safety latch fully closed.
7. Do not exceed the rated WLL. Do not side-load or point-load the hook outside its designed direction of pull.
8. Inspect periodically for cracks at the weld, hook deformation, safety latch wear, and corrosion damage.

Important:
Welding of lifting equipment must be carried out by a qualified welder in accordance with applicable welding procedures. The completed weld and hook installation must be proof-load tested and certified by a competent person before being placed into service, in accordance with LOLER 1998.

Inspection and Maintenance

Inspect before every use, including checking the hook body for elongation or deformation, the safety latch for damage or weak return spring, the weld for cracks (particularly at the toe of the weld), and the surface coating for damage or corrosion. Arrange thorough examination by a qualified engineer at least every 6 months when in regular use, in accordance with LOLER 1998. Replace the safety latch assembly when wear is noted; replacement latches are available from Yale.

Warranty & Support

All Yale ASHS weld-on hooks are covered by the Yale manufacturer warranty against defects in material and workmanship.
