David Round Variable Speed Chain Hoist
Specifically designed to improve mold placement accuracy, the two-speed die setter low speed electric hoist features ultra low speed hook movement for exact die positioning as well as the standard speed for normal use. The low speed setting may be set to 1.5 feet per minute without sacrificing the normal lift speed of the electric hoist to reduce die impact damage and shock loading conditions
The variable speed hoist feature permits fine mold positioning without continuous hoist jogging. Low speed hook travel on David Round’s die setter electric hoist is available in both the up and down directions unlike other creep or step-controlled hoists that may only lower at the low speed setting.
Both the standard and low speed settings may be adjusted in the field to meet specific application requirements with these electric hoist products. A variety of pendant configurations are available as well as low-speed trolleys, jib cranes and monorail systems.
- Position and handle dies at ultra low speeds as low as 1.5 FPM
- Various models available from 1/2 to 5 ton load capacities
- Position loads precisely with continuously jogging hoist
- True vertical lifting path eliminates side-to-side hook travel
