Clean Room Strap Hoists
David Round Clean Room Strap Hoists are designed for Class 10,000 use to meet the clean room processing needs of pharmaceutial processors and high-tech manufacturers. CRS-Series strap hoists are designed for operation inside controlled environments. Various models and trolley options accommodate loads up to 4,000 pounds.
Lube-Free Lifting Strap
By using a polypropylene lifting strap, CRS-Series hoists eliminate the contamination associated with the surface lubrication of chain and wire rope. Metallic dust and particulate contamination caused by chain abrasion and wire rope wear is also eliminated.
Crack and Crevice Free Construction
The easy-to-clean open design of CRS-Series strap hoists features stainless steel surfaces polished in addition to flush mounting faces, ground welds and plugged fasteners to reduce the likelihood of contaminant build-up.
