7790 SERIES HOISTS

SPARK RESISTANT

1500 lb (682 kg) - 3000 lb (1364 kg) Capacity

CONTINUOUS HEAVY-DUTY APPLICATIONS

7790 Series Spark Resistant Hoists are designed for Division I applications where, under normal operating conditions, the atmosphere contains hazardous concentrations of flammable gases, dust, or other materials.

Designed for maximum operational efficiency in the 1 to 1/2 ton range, these hoists come complete with 10 feet (3m) of standard lift and either 6 feet (1.8m) of pendant control or 5 feet (1.5m) of pull chain control.

SPARK RESISTANT FEATURES:

Stainless steel load chain and solid bronze hooks to prevent accidental sparking.
Pendant control handles, when ordered, come standard with an industrial-grade vinyl cover. Pull chain controls come standard with zinc-plated pull chain.
Hoist capacities are reduced and speed adjustments are locked into place to maximize chain life.

DIVISION 1 & 2 APPLICATIONS

The following definitions may be used as a guide. The actual Division distinction for each application must be determined by your local inspecting authority of the fire underwriters.

DIVISION I

Atmospheres containing hazardous concentrations of flammable gases, dusts, or fibers, continuously, frequently or periodically, under normal operating conditions.

DIVISION 2

Atmospheres, normally non-hazardous, in which a hazardous concentration of flammable gases, dusts, or fibers, occurs when a container or handling system fails, or the ventilating system which normally keeps the concentration non-hazardous fails.
