David Round Explosion Proof Electric Chain Hoist
David Round’s explosion proof hoist products are specifically designed to meet electrical standards required in hazardous or classified manufacturing and processing areas. Unlike our competitors, our explosion proof chain hoists come with the spark resistant features because that is the safest way to lift your load in a hazardous environment. We also offer hoists intended not only for Class I environments, but also Class II.

Description David Round Explosion Proof Electric Chain Hoist Brochure
EXPLOSION-PROOF/DUST IGNITION-PROOF:
- Featuring NEMA 7 enclosures, pendants and fittings as well as explosion-proof rated motors as required, EPC-Series electric explosion proof chain hoist products are intended for H-4 operation in Class I environments with flammable gasses and vapors AND Class II locations where combustible dust is present. Units are further configured for use in either Division I or II rated facilities.
SPARK-RESISTANT HOIST FEATURES:
- All EPC-Series explosion proof hoist products include spark-resistant features to further reduce the likelihood of inadvertent sparking during normal lifting operations. Each Explosion proof hoist is supplied with rubber bumpers in addition to stainless steel trolley wheels, load chain, bottom block and hook.
- David Round manufactures both explosion proof and dust ignition proof apparatus as specified by David Round’s interpretation of Articles 500-504 of the National Electric Code (2002). However, it is the customer’s responsibility to determine the class, division and group for each hoisting application and to ensure that each David Round product intended for use in a hazardous environment specifically meets the requirements for the intended area of use prior to installation and operation.
