spark resistant hoist

  • Spark Resistant Hoist

    The contact and friction between different parts of a hoist can cause sparks which can ignite flammable gas and dust.


    There are several key factors which affects the potential ignition, including: the type of materials in contact, the pressure or speed of material contact, corrosion on contacting surfaces and lubrication.

    Contact between steel materials can cause spark, so hoists made of steel parts are not suitable for potentially explosive environments.


    The spark resistant hoists cost more than regular ones and they may decrease the lifting capacity.
