FORGED HOOKS - GHM Industries Inc

1 FORGED HOOKSM iller HOOKS are produced in accordance with the follow ing DIN standards: DIN 15400- Lifting HOOKS , materials, mechanical properties, lifting capacity, stresses DIN 15401- Single HOOKS DIN 15402- Rams horn HOOKS (double HOOKS ) with and without bottom hole DIN 15402- Quad HOOKS (based on DIN 15402) DIN 7540- Eye hook class 8 (grade 80) DIN is the German Institute for Standardization (Deutsches Institut f r Normung) and has been based in Berlin since 1917. DIN has historically developed the detailed and exacting standards used in German engineering and is the body that represents Germany in international standards organ ization s. Shank HOOKS HOOKS feature markings of fixed distances ( y dimension) which allow confirmation that no deformation has occurred in use, under testing, etc. This dimension is a detail of the DIN requirement. HOOKS are identified by hook number and material.

2 Each hook number maintains identical dimensions across a number of raw materials and has increasing load capacity depending on the material used. HOOKS are FORGED and heat treated for optimal strength and toughness properties. Shank hook forgings are available in three increasingly stronger materials: DIN class P, fine-grained carbon steel. St-E355/St-E420, similar to ASTMA573 Gr. 65 DIN class T, alloy steel 34 CrMo4-34 CrNiMo6, similar to SAE 4135/4340 DIN class V, super alloy steel, 34 CrNiMo6-30 CrNiMo8, similar to SAE 4340/4337 In the follow ing selection tables for shank HOOKS , three working load limits are indicated for each hook number depending on the material selected. Hook forgings have a design safety factor of 5. Safety latches are included. Longer shanks are available (dimension B , +150 to +200mm). Miller also offers hook machining with matching nut for your particular application from our stock of DIN HOOKS or from the hook manufacturer of your choice.

3 This catalog includes HOOKS up to working loads of 500 metric tons. Please inquire for higher load requirements. Eye HOOKS See detailed eye hook tables immediately following the shank hook tables. Our DIN 7540 Grade 80 Eye Hook features the traditional eye-ring of circular cross section allowing the maximum degree of motion in the connection and is available standard in working load ratings up to metric 400 tons. These are FORGED from34 CrNiMo6V alloy steel with safety latch and can be adapted for ROV use. Design factor is 4:1. Our Shackle Eye Hook features an eye of cylindrical section for a close fit onto the shackle pin, limiting motion and evenly distributing the load. These are similar to DIN 15401 shank HOOKS and are FORGED from the class V alloy steel material noted above. Design factor is 5:1. Our Shackle Eye HOOKS include a locking safety latch and can also be adapted for ROV (remotely operated vehicle) use.

The cylindrical cross-section of the eye assures uniform pin loading while limiting relative hook motion. Based also the DIN norms, they are typically FORGED from the strongest DIN "V" material class (see above) and carry a 5:1 design safety factor and a positive locking latch. Adaptable for ROV (Remotely Operated Vehicles) use, these eye HOOKS fit standard shackles and also are available in customized versions.
