Ultimate Upper Limit Switch
The Ultimate Upper Limit Switch can be directly attached to the wire rope Load Limiter (ULS+LLL factory install only) or can be purchased and used separately (ULS). The Ultimate Upper Limit Switch can be used in series with existing hoist upper limit switches (paddle type etc.). The rising block (hook) lifts the weight of the switch causing the switch mechanism to open. This can be used to drop out the mainline contactor, the UP contactor or a signal to a variable speed drive such as Power Electronics® Micro-Speed® drives for overhead hoists. This device, along with the overload system, can save thousands of dollars in maintenance and repair costs per year. As always, this device does not substitute regular hoist maintenance, proper hoist use and regular OSHA hoist safety inspections.
For cable diameter 1/4" - 1" (6.35mm - 25.4mm)
