UMMIT CWL-010 Electronic current Load limit control overload protector safeguard load limiter for AC motor hoist and crane

Description:

This overload limiter CWL-010 is a fixed protection device specially designed to protect the AC motor when it is mechanical overloaded. When the external mechanical overload or impact load, the motor current will increase, then the current transformer (CT) detects the working current and compare it with the set value, when the working current exceeds the set value, and it is judged to be overloaded. At this time, the overload relay is triggered and immediately cut off the power supply. At the same time, the alarm buzzer sounds and the warning light flashes to remind the operator that the machine is overloaded. It is a highly reliable and economical overload protection device.

Features:

1. Reliable &economical overload protection device
2. Particularly designed for the chain electric hoist&crane
3. Easy installation and simple debugging

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 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

- Current detection overload limiter (CWL-010)
- Cross head limit switch
- Geared limit switch(worm rod lift switch)
- tension link load limiter (RHP-X)
- Load limiters with analogue or digital outputs(OMS-820)
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
