The lifting and
handling problems associated with slab
and plate handling in the metals industry
are familiar to Street Crane as the
company was originally situated in Sheffield
which was England’s ‘Steel
City’.
The steel and aluminium industries in
particular have a need to lift slabs
and billets by crane often at high rates
of handling.
In most applications the best solution
is to incorporate a slab grab into the
crane control system such that grab
opening and closing and a slewing mechanism
can be operated from the crane cab pendant
or remote controller.

Plate
poses different problems and in the steel
industry magnet beams can be permanently
roped under the crane or suspended from
the hook. Another solution, which Street
has supplied for aluminium and steel,
is vacuum lifting.
Grabs and on the hook devices can cause
rope deviation on standard hoists and
open winch hoists such as the Street
heavyduty VX hoist are recommended. |
