The air hoists feature a motor brake system which does not require supplementary lubrication. This prevents the emission of oil droplets in the exhaust air. The devices are unaffected by the sort of dusty atmospheres created when handling powder or granulated ingredients, and are impervious to washdown or chemical cleaning procedures. Hoists and trolleys are nickel plated to provide smooth, easy-toclean surfaces, stainless steel chains, load sleeves and lift hooks can replace these external exposed elements. A reduction in the number of components has increased reliability, improved operating economy and reduced routine maintenance. The range for food industry applications include the Profi series hoists and trolleys rated for 250-2000kg lift operations, low headroom hoists rated from 500-2000kg and ultra-low monorail hoists covering from 4-16 tonnes capacity. Big bag handling hoists in single hook (1t), and twin hook (2t) variations can also be supplied.
