Hoist drive with brake

A crane hoist drive: line contactor, converter drawn with its terminals, braking resistor and a motor with a holding brake. The control circuit has an emergency stop, up and down relays with limit switches and interlocks, and a brake coil released by a relay output of the drive.

Free to use and modify in your own projects, including commercial ones. The ZIP holds the sample drawing, a template, a plot style table and a README; no add-in needed. The data in the drawing is made up, so it is not for design or construction. Provided as is, without warranty. Library terms (CXL-1.0)
