Wire Rope Hoist Load Limiter
When your load exceeds the lifting capacity of you crane, load limiters will cut power from lifting your load higher. This can save your life, avert lost downtime from a damaged crane, and prevent expensive accidents and insurance claims.
If you are using a hoist that is not equipped with overload protection or require a new load limiter, let us know. We will supply you with a limit switch that meets your exact needs. Whatever your single line load capacity, work environment, or wire rope size, your limit switch will be custom made to your requirements.
These load limit switches can be installed onto a hoist at the rope's dead end or equalizer sheave. It can be designed for other installations with a power reel or remote control. You'll find these limit switches to be extremely easy to install - you simply clamp them onto the wire rope without having to cut the rope or make modifications to the hoist.
The load limit switch is activated from the deflection of the rope when the hook lifts the load. This increases the tension of the rope, which activates the limit device. The device can be electrically connected with the hoist's switch for either up or down motion, depending on the motion to be controlled. As well, it can work as both an upper limit switch and load limit switch as a special order.
