Record alarm device integrates many functions of tower crane safety devices, including moment limiter, weight limiter, amplitude limiter, rotation limiter and height limiter. And we use together micro electronic technique and information and communication technology. So it's high-quality and high-efficiency.
Besides, its height and amplitude sensor adopt CPLD to constitute four multiplying frequency and direction-distinguishing circuit to improve detective resolution and eliminate tremble error. In the meantime, with super memory capacity, it can continuous record the data of tower crane working, and can playback the record when needed.
Can monitor any site according to tower crane designed torque curve
Can show in time current and rated working parameter of tower crane to make driver know working condition.
Can accurately collect cage amplitude, hook height, rotation angle and height in time and compare them with set data. Once they're out of range, it'll make sound and light alarm.
Can store the working data automatically and more than 1.6*104 times working cycles, which can be used to judge tower crane's examination, overhaul and accident.
Adopt non-contact and high-accuracy measurement technology to increase system life and efficiency.
Can complete debugging of system just in cab, because of powerful and advanced operating system
