After
matching the crane to your application, the
next step is to choose a compatible hoist and
trolley. When selecting a hoist/trolley combination,
considerations include:
- Capacity
-- Hoist and Trolley capacity cannot exceed
the rated load of the crane. Apart from CMAA
and ANSI requirements, the trolley might not
even fit on the beam.
- Trolley
Type -- Manual or Powered?
- Powered
types include Electric, Air, and Hydraulic.
You may also decide on the type of pendant
or remote you want. These power options
are discussed in the links below.
- Hoist
Type -- Manual or Powered?
- As
with trolleys, you have a wide range of
options for power types.
Why
Powered Hoists?
Apart
from saving manual effort, the powered options
may be much quicker. Where it can take minutes
to raise a load with a geared manual hoist,
this can be seconds with a powered version.
Still, extreme speed may not be possible or
desired with some loads. Nonetheless, you may
need a powered hoist even with intermittent
use. Cranes take up valuable floor space and
may prevent other traffic from moving on the
shop floor. You want to lift and leave.
Answering
Fit Questions
Capacity
and speed are just two selection choices. You
may also have to decide what an appropriate
trolley height is. The height under beam may
move the selection to a low-overhead design.
Or you may have a long drop, as with a crane
mounted over a pit. Or the crane may be used
to raise an air-conditioner from ground level
to a multi-story roof. Each of these scenarios
yields a different set of choices. The experts
at Wallace can answer all these questions.
Inside
or Outside?
Equipment
for outdoor use may have to be weatherproofed.
Depending on the hoist and trolley types (powered,
manual, electric, hydraulic, etc.) you will
likely need a different set of protective precautions
to ensure a longer service life. Consult with
our sales staff to get the best methods to ensure
uninterrupted performance.
