Summarize

Under appointment of Combo of Tower Crane Introduction,we began designing and manufacturing the multifunction traveling limiters with angle control in accordance with the technology form POTAIN Co.of France.The limiters had passed the approval of Ministry of Urban-Rural Construction and Environmental Protection in 1987,and achieved excellence new product is up to its specifications.

Application

The limiters can be applied widely to the tri-dimensional control and the traveling limitation of the hoisting and conveying machinery in the construction of buildings,port,mine,hydro-engineering,construction,etc.They are provided with the features of small volume,multifunction,high precision,adjustable limiting mechanism,well versatility and easy installing and adjusting.The limiters adopt the structure of adjustable machinery memory and have high reliability and sensitivity.When a limiter with the sensors and the relevant display form a complete set,instantaneous position of three dimension space can be simuated and displayed.
