Features

    Spark Resistant Features

    • Stainless steel load chain and solid bronze hooks to prevent accidental sparking.
    • Pendant control handles, when ordered, are covered with an industrial-grade vinyl grip. 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.
    • Trolley models are supplied with bronze wheels.

    Division 1 & 2 Applications

    • Division 1 (Spark-Resistant air hoists are required)

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

    • Division 2 (Standard air hoists are required)

      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.
