components for chain elevators / chains RC4 and RC5

RC 4
Highly wear resistant elevator and conveyor chains, marked RC 4, produced according to DIN 764 / 766, made of manganese alloyed steel (e.g. 21Mn4Al), surface hardness min. 750 HV measured 0,25 mm below the surface, carburizing depth HTÄ 0,1d ± 0,01d, hardening depth EHT at 0,06d more than 550 HV up to 28 mm-O, 30 mm-O and bigger at 0,05d more than 550 HV, proof strength 125 N/mm2, breaking strength 250 N/mm2.


RC 5
Highly wear resistant elevator and conveyor chains, marked RC 5, produced according to DIN 764 / 766, made of chrome and nickel alloyed steel (e.g. 15CrNi6), surface hardness min. 750 HV measured 0,25 mm below the surface, carburizing depth HTÄ 0,1d ± 0,01d, hardening depth EHT at 0,06d more than 550 HV up to 28 mm-O, 30 mm-O and bigger at 0,05d more than 550 HV, proof strength 150 N/mm2, breaking strength 300 N/mm2.


Width between centres, circulation frequency and other factors effect on creation of additional loads.
Considering these additional loads the increased safety ratio working load : breaking load is required
- vertical conveyers: ratio 1: (10 - 16) for short link chains
ratio 1 : (8 - 15) for middle long link chains
- horizontal conveyers: ratio 1 : (8 - 12,5) for short link chains
ratio 1 : (7 - 10) for middle long link chains

Long – link chains according to DIN 764

The sections are usually used in lengths of 3, 5, 7 and 9 links. It is necessary to specify the required lengths of the chain section in the Purchase Order. Also it is necessary to agree upon other lengths of the chains in advance.
The general tolerances for individual lengths of chains: +0,40% / -0,15% = 0,55% max
