Description / Abstract:
This International Standard defines the performance requirements of a
retrieval device mounted on
an earth-moving machine listed in ISO 6165. Requirements for
verification testing, if needed, are
included.
Studies have shown that the tow rope, used for retrieving a large
disabled or mired earth-moving
machine is seldom larger than 40 mm diameter wire rope. This is
typically the largest size that can
be handled by the person connecting the tow rope to the machine.
Therefore, this International Standard is applicable to
machine-mounted retrieval devices of
capacities not exceeding 10 6 N. This value corresponds to the
minimum breaking force of a 40
mm diameter Group 3 wire rope with steel core as listed in ISO 2408.
NOTE 1 In accordance with ISO 6750, information on the location and
instructions for proper use of
retrieval devices is provided in the operator manual.
