Slpit type OMS-370C-RH-BC 5T-10T overload guard/load guard / force control switch / crane guard / load limiter
The split type load limiter constitutes of the wire rope load cell RH-BC series and control unit OMS-370C, this overload limiter is particularly designed to prevent overloads that usually happens on cranes, overload cranes, good's lifts, lifts, elevators, etc. The RH-BC Clamp-on Load Cell simply clamps onto a wire rope dead end and is connected by integral signal cable to the control unit OMS-370C for permanent overload detection with streamlined connectivity and relay outputs. the electronic overload limiter practically does not require assembly and its installation is fast and easy.
The wire rope clamp on force transducer RH-BC is compatible to other control unit such as OMS-820, SUMT-QZX(B) produced by us, with the lifting load limiters,

We SUMMIT has been providing versatile load-limitation systems for all types of cranes and especially overhead cranes. In particular, we have supplied them to the very important players in the lifting and material handling industry as well as in steel industry. That is why we can claim that we have a solid experience and are highly dependable as regards load-limiting devices for cranes which enables us to equip the most complex of systems.
We offers a very wide range of overload limiter and applicable to versatile lifting industry application:
- Load cells and load pins (from 1000 kg up to 10T, higher capacity on request) such as Split type overload limit switch: OMS-370C+CRN-GX, OMS-350+CRN+GX and so on.
- Clamp on wire rope load limiter:SUMT-QZX(A), OMS-370C+RH-EC, OMS-370C+RH-BC and so on
- Geared limit switch(worm rod lift switch)
- tension link load limiter
- Load limiters with analogue or digital outputs;
Module design and easy and free combination to suit different installation demand.
Solutions to meet your integrated needs
Application:
Overload limiter prevent accidents occurring due to the raised load dangerously exceeding the normal value as established by the manufacturer or by the user of the lifting device. It makes a vital contribution to the safety of operatives.
A comprehensive kit for crane/hoist overload protection that includes everything needed to install or retrofit on bridge cranes is now available from SUMMIT load weighing Systems.
