Tower Crane Safety Monitor System Multiple Towers Anti-Collision Function

Tower Crane Spare Parts Safe Load Moment Indicator on Sale
RC-A6 Tower Crane Safe Load Moment Indicator Overload Protector Cxt/90iic
Anti-Collision and Zone Protection System for Tower Cranes (CXT/800)New generation of load moment indicator is suitable for all models of tower crane, making use of special sensors to provide the tower crane operator with actual and correct crane working state. It indicates the moment of force applied on the crane, the hook amplitude as the height of the load increase, the crane rating, and the actual hoisting capacity of the tower crane. In case the load reached 90 percent of crane rating at a particular moment, it will provide an early warning to the crane operator through a slow blinking red light. When the load( along with the hook amplitude) reached 105 percent, the load moment indicator will automatically trigger an alarm and will stop the lifting gear from lifting the load upward.Product DescriptionOverload Monitor Tower Lightweight Load Weight Indicator Easy Install Stable Crane Moment Limiter For Sale:The QCX-GL load lifting limited is used in safety protection device of the hoisting machinery . The design and production of the products are in strict accordance with the national standard GB12602-90 " hoisting machinery protection safety technical specification ".
Structure:This product is composed of two parts by the bearing pressure sensor and control instrumentation , with digital display from the weight and automatic overload alarm and cut off the crane lifting loop power function . Applicable to the bridge carne and gantry crane equipment.Advantages:Compared with other similar products , this products have many characteristics, eg : high cost performance, economic, good reliability, easy install .Specifications

When the load reaches 105% of the set point comparator action, to avoid starting shock load caused instant false overload, set a delay circuit, delay of 1-2 seconds, it is determined if the overload persists, really overloading, immediately cut off the lifting motor power, the red indicator light. Execution control relay to DC relay, the relay does not operate when normal lifting.
The device control relay contacts in series in the the crane hoisting control loop, overload control relay action, lifting loop cut, cranes stop lifting job, but the job does not affect the other direction, the circuit two The group DC power supply: ± 6V for sensor and secondary instrument, ± 8V for weight digital display.User NoticeOverload Monitor Tower Lightweight Load Weight Indicator Easy Install Stable Crane Moment Limiter For Sale.1.User when ordering please click models, specifications, code unified form of expression, and indicate the length of the cable, the Secretary will be charged for the length.
2. Lifting, the upper and lower positions weighing numerical slight difference is caused due to the length of rope on the drum is inconsistent, but integrated error required is less than 50% FS.
3.The device is limited from the overload protection, measurement scales generally do not make use of.
4. The device fall safety protection device, but not equipped with this device two ignore safety procedures
