Spark Resistant Bridge Crane

TC American Monorail installs a custom configured XP INTERLOCK spark resistant transfer crane in a paint booth area with flammable solvent fumes.  This crane utilizes multiple “patented track” sections that are interconnected by special locking transfers at key transfer points, along with spark-resistant components for safe, explosion-proof operation in a hazardous area. To eliminate the sparking risk all crane components that could act as a potential spark source were redesigned or replaced. The standard electric hoist motor was replaced with a 2.8 hp air motor, fitted with a spark-resistant stainless steel festoon system to carry the air lines. Spring loaded rubber tire drives are used on the end trucks, along with bronze idler wheels and side rollers. All metal-to-metal contacts that could act as potential spark sources are protected by stainless steel or bronze buffers to insulate the contact areas. The trolley drive system utilizes a ¾ hp air motor, with stainless steel safety drop lugs, to achieve a travel speed of 50 feet per minute.
