concert hoists are designed for lifting and transporting of materials only. Under no
conditions or circumstances, either during initial installation or in regular use, are hoists to be used for
lifting or transporting of personnel. For additional safety, precautions such as redundant systems, safety
lines from load to structure or enhanced safety features such as the BGV-C1 hoist can be used.
2.1 Environment
The hoists are designed for indoor use and limited outdoor use where the ambient temperature is
between 14°F [-10°C] and 104°F [40°C], elevation is less than 3300 ft [1000 m] and the relative humidity
is less than 90%. The hoist control enclosure has protection rating of NEMA 3R type.
The hoists can be used outdoors with some precautions such as specifying the hoist with a drain hole in
the load sprocket compartment, covering the hoist body/enclosure with a vinyl rain cover, or protecting
the hoist under a shelter. The vinyl rain cover would cover the hoist body/enclosure after the hoist is in
position. The hoist cannot be operated when the vinyl rain cover is covering the hoist body/enclosure.
Without these precautions, continuous exposure to extreme weather conditions will lead to damage of
electrical components.
2.2 Sound
Level
The sound intensity level of the hoist in the assumed operating location does not exceed 76 dB.
2.3 Proper
Installation
Hoists must be installed clear of any obstruction that could prevent the top and bottom hooks from being
inline.
2.4 Hoists for Ground Supports
Use single fall SM10 hoists for ground supports. Using a SM10 hoist reduces chain wear and risk of chain
twisting. Idler wheels on the ground support must have matching grooves and proper pitch diameter.
