HMLK2800B is the newest model of load moment indicator,it is the unique item will realize compatible with level-jib and luffing tower crane.Also it is a high-end product you can set up the tower crane load chart data at site.This system based on high-stable ARM system,with color touch screen,high-precision sensor testing technology,make the system owns most direct and accurate data display,harmonious image display.It can show the rated load,actual load.trolley range,(slewing angle),hook height,moment rate and current wind speed,pre-alarm and interference before the tower crane be in violation working.

Through the remote GPRS module,the system will transmit the real-time working data to the server.through the WEB broswer, you can check and manage the trower crane operation all over the country at real-time.And also you can locate the accuracy position of the tower crane through the GPS module.
