Impact Energy Av, in J (ISO-V), as a test

temperature of +20ºC, /-20ºC with direction of

sampling 3)

Upper yield strength ReH1 or 0,2% proof stress Rp0, 2

1) Use of strength classes given in brackets should be avoided where possible.2) The values given in brackets are information only, the test is to be carried out at -20ºC3) ‘L’ stands for longitudinal direction , ‘Q’ for traverse direction. Where the sheet is wider than 600mm the test piece shall be taken in the traverse direction

1) See figures 1 and 2. The specified values have been taken from DIN 15401 Parts 1 and 2 and DIN 15402 Parts 1 and 2.

2) Where DIN 17200 steel is used, or where the diameter of the material is greater than 250mm (cf. Stahl-Eisen-Werkstoffblatt (Iron and steel materials sheet) 550), the following requirements shall also be met and be part of the contractual agreement. a) The total amount of aluminium in the steel shall be at least 2%, or it shall be verified in another way that the nitrogen in the steel is fixed. b) At a test temperature of -20ºC, the impact energy shall be at least 27J, as measured on an ISO-V notch specimen taken in the longitudinal direction.

3) For reasons of efficiency, it shall be permitted to use StE 355 steel in place of StE 285 steel.

This table establishes a general claification of cranes basedd on the number of operating cycles to be carried out during the expected life of the crane and a load spectrum factor which represents a nominal state of loading. Classification considers only the conditions which are independent of the type of crane and the way it is driven.

• Ganchos sencillos desde el nº4 hasta el 250 S/DIN 15401. THG ofrece la posibilidad a sus clientes de entregar sus productos en bruto de forja, mecanizados S/DIN 15401 parte 2 o completamente mecanizadas S/DIN 15411.

• Desde el gancho nº4 hasta el nº 16 THG for-ja sus ganchos con geometría RSN y desde el 20 hasta el 250 en geometría RFN.

• Desde el gancho nº 4 hasta el nº 50 son forjados en matriz cerrada por lo que su longitud L1 no es modificable.

• Desde el nº63 hasta el 160 en matriz abier-ta por lo que la variación de la cota L1 es posible a un bajo coste.

• Los ganchos nº250 se realizan por medio de forja libre.

• Simple forged hooks from nº 4 to 250 S/DIN 15401. THG offers its customers the possibil-ity of delivering their products rough forged, machined S/DIN 15401 part 2 or fully ma-chined S/DIN 15411.

• From forged hook number 4 to 16, THG forg-es its hooks with RSN geometry, and from number 20 to 250 with RFN geometry.

• Forged hooks 4 to 50 are produced using closed die forging, therefore their L1 length is not adaptable.

• From 63 to 160 with open die forging, there-fore varying the L1 level is possible at a low cost.

• Forged hooks number 250 are made using free forging.
