Chester
Electric Low Headroom Chain Hoists are designed for those applications where
headroom is limited.
Engineered around proven designs, these hoists provide smooth, quiet, trouble-free
operation in a variety of

|
|
The
Chester Electric Low Headroom Chain Hoist is not adjustable for varying
beam sizes. Each unit is custom-built
to fit the specific beam specified in the order. Beam size, height, flange
width and curve radius are required for all others. |
|

HOW
TO ORDER: |
When specifying
a Chester Electric Low Headroom Chain Hoist, the following parameters
should be considered. Determine the specific requirements and clearly state
them when
ordering. The following checklist will be of help: |
|
|
|
|
|
1. Load weight
to be lifted. |
7. Beam sizes and
weight (to determine
trolley wheel specifications) |
|
2. Lift or reach
required |
|
3. Control drop
required |
8. Trolley type
(plain, hand-geared or
motorized) |
|
4. Power supply
available |
|
5. How often load
must be lifted (specify
number of starts power cycle, number of
cycles per hour, on-time per hour) |
9. Controls (may be expressed
as function,
such as Hoist Up-Down, Trolley
Forward-Reverse, etc.) |
|
6. Operating environment (moisture,
corrosive fumes, explosive vapors,
temperature, etc.) |
