1. Selecting the correct Hackett C4 chain block
1.1 William Hackett C4 chain blocks are manufactured in
accordance with BS EN 13157:2004+A1:2009, ASME
B30.16-2012, AS1418.2-1997 and SANS 1594:2007
1.2
William Hackett C4 chain bocks are assembled, chained
and tested in the UK to the height of lift specified by the
end user.
1.3
The configuration of chain block assemblies are
demonstrated below and are in accordance with the
product specification, dimensions and safe working load
(SWL) recorded in Table 1.
Table 1: Product specification, dimensions and SWLs for William Hackett C4 chain blocks
1.4. William Hackett C4 chain blocks can be used within an
operating temperature range of -40°C to +55°C.
1.5. In accordance with statutory requirements (e.g. The
Lifting Operations and Lifting Equipment Regulations
1998), all lifts using chain block assemblies should be
planned by a competent person; require risk assessment
and the production of a task method statement; and be
subject to execution by suitably trained operatives under
the supervision of a responsible person. The
specification of the chain block assemblies required to
achieve a safe lifting operation must be determined by a
competent person.
