This standard BS 4831:1985 Specification for shackle type connector units for chain conveyors for mining is classified in these ICS categories:

• 73.100.40 Haulage and hoisting equipment
• 53.040.20 Components for conveyors

This International Standard specifies the requirements for a range of shackle type connector units for use with chain conveyors. Each unit consists of the following components:

1. shackle type connector;
2. connector bolt;
3. connector nut.

This International Standard is not intended to indicate a complete design, but it gives sufficient detail to ensure dimensional compatibility with chains complying with ISO 610 and scraper bars complying with ISO 5612. The connector units specified are intended for use as part of 14, 18, 22, 24 and 26 mm diameter chain assemblies in which the connectors are fitted tightly on to scraper bars.

The Figure illustrates the connector; critical dimensions are specified in Table 1.
