Description / Abstract:
This International Standard provides a uniform method of calculating,
and a test method for
validating, rated lift capacity as presented in commercial literature
for pipelayers and wheeled
tractors or loaders equipped with a vertical-only pivoted, hydraulic
or mechanically operated, side
boom. The rated lift capacity considers hoist mechanism limits,
tipping loads and rope factor.
After the lift capacity has been calculated and validated, a reduction
factor is applied to
establish the rated lift capacity for the specific pipelayer or
wheeled machine configuration.
This International Standard applies to machines having a lift capacity
greater than 10 000 N when
used in lifting applications. It includes pipelayers as defined in ISO
6165 and ISO 7136, and
wheeled tractors and loaders as defined in ISO 6165, ISO 6747 and ISO
7131.
