Harsh environment upgrade kit keeps overhead cranes working

By Staff -- Modern Materials Handling, 10/1/1998

Offering protection for cranes operating in a harsh environment, this upgrade kit enables cranes to operate in extremely high humidity or highly caustic areas. The electronics of a crane's control box are housed in a fiberglass or stainless steel, gasketed enclosure, which comes complete with press latches to confirm a perfect seal. All external wires run through water and gas-tight press seals so that the control panel can even be submerged in water or chemical baths and remain functional. The crane's push-button pendant is also provided with seals, gaskets, and button covers.

Covered with a chemical resistant varnish, motor windings include seals at all openings. Bearings are sealed, and the runway conductor bar is rubber-gasketed to prevent condensation from corroding the bar. Upgrade packages are available on all new cranes and can be retrofitted to some existing cranes.
