Renold can supply leaf chain for use in machine tool...

Renold Lifting Chain Catalogue I 13 Preparation Installation of Chain Maintenance Schedule Check equipment to ensure that general requirements are correct (e.g. sprockets, sheaves, means of adjustment). Should endwise float of shafts be present, make due allowances so that alignment is correct at the mid position of float. Check condition and rigidity of the shafts and bearings, particularly if there has been considerable previous service. Replace or rectify if necessary. When alignment is correct within closest practical limits, drive any keys home and take a final check. Regular chain...

14 I Renold Lifting Chain Catalogue Section 1 Chain Installation and Maintenance Chain Protection Abnormal Ambient Temperatures Environmental Factors A new Renold chain should always be stored in its original packing until installation. Renold chain is lubricated at the factory, but this lubrication will not stand up to outdoor conditions for prolonged periods particularly where there is a salt water atmosphere. For elevated temperatures up to 250°C, dry lubricants, such as colloidal graphite or MoS2 in white spirit or poly-alkaline glycol carriers are most suitable. Effect of Temperature...

Renold Lifting Chain Catalogue I 15 To Measure Chain Wear Chain wear can be ascertained by length measurement as follows: Fig A: Section 1 Chain Installation and Maintenance M Lay the chain on a flat surface and, after anchoring it at one end, attach to the other end a turnbuckle and a spring balance suitably anchored. Apply a tension load by means of the turnbuckle amounting to approximately 5% of the chain breaking load. As an alternative to the use of turnbuckle and spring balance, the chain may be measured in-situ with a nominal weight in the lifting system. Fig B: • Measure length ‘M’...

16 I Renold Lifting Chain Catalogue Section 1 Chain Installation and Maintenance General A correctly installed chain will enhance service life and ensure safe operation. When ordering replacement chains consult your operating/service manual to ensure that the new chain or chains will be supplied to the correct size, length and configuration. Where a lift truck has a pair of chains, a new pair should always be ordered and replaced. The replacement of only one chain will lead to premature failure of both the new and used chain. Sprockets Examination of the tooth faces will give an indication...

Renold Lifting Chain Catalogue I 17 Disconnecting Roller Chain Renold Chain has end softened pins and for chain up to 1” pitch the pin may be removed using a suitable chain extractor. Otherwise follow the above procedure. Section 1 Chain Installation and Maintenance Fig A: Method 2 - Pressing In order to obtain the longest life from a leaf chain, Renold recommends the following procedures for cutting short chain lengths from a new coil or shortening an existing leaf chain. • Method 1 - Grinding Two pins need to be removed. Both pins should be in the same outer link plate. With a grinding...

18 I Renold Lifting Chain Catalogue Section 1 Chain Installation and Maintenance Safety Warning FLT Chain Never use a connecting link in any lifting application to join leaf or roller chain lengths together, in any manner that does not have the truck manufacturers approval. Misuse of connecting links will render your chain warranty void and subject the user to a safety hazard. Renold Distributors will not supply connecting links for this purpose. When chains are sold as assemblies, the connecting pins must be fitted to the chain anchor and chain using the approved method outlined by the...
