May 01, 2002 Model D-BS requires low hand forces, letting operator move loads into position without pendant control. It can operate at speeds up to 400 ft/min. Speed limiter protects operators should load attachments accidentally let go or if load is suddenly released, and prevents cable from accelerating at unsafe speeds. Models D-BP 55 and D-BP 110 handle workloads of 0-125 lb or 0-250 lb, respectively. Both automatically adjust to any load without operator intervention.
