Safety protection monitoring device (for short: Safety monitor) is used to real time monitoring and can avoid safety accidents that caused by operators' negligence or misjudges.
The device includes tower crane black box, tower crane wind speed transmitter, weight sensor, radius sensor and lifting height sensor, meantime can change different assemblies. Monitoring data can transmit wireless between main board and extension, the effective transmitting distance is 3000m.
Main function:
(1) Data recording. In the process of tower crane, in sampling periods of 10ms, it collects and records work parameters of tower crane, including loading, temperature, wind speed, alarm record and moment. Pulse signals that is used to calculate height, radius and trolleying angle (can increase slewing) use interuption to count, the results of counting save one time each 10ms and can save 1.5 hours (5000 PCS) records, and datas and events will be transferred to FLASH when power fails or capsizing cases of tower cranes happen.
(2) Safety protection. The device can realize various safety limiter functions, including hoisting moment limit, hoisting weight limit, lifting height limit, radius limit and slewing angle limit. When tower crane overload, system will provide controlling signals, allow crane to move toward safety direction and forbid it to run to dangerous direction.
(3) Realtime display function. Liquid screen display key parameters of tower crane instantly (loading, radius, hoisting moment and wind speed) and main operation (lifting, trolleying etc. ).
Shandong Minglong Construction Machinery Co., Ltd, an incorporated company restructured based on former Shandong Zhangqiu Crane Factory, is a professional tower crane manufacturer recognized by the Ministry of Construction. It was one of the first enterprises that achieved Production License issued by the Ministry of Construction in 1988 and one of the enterprises that achieved Special Industry Tower Crane Manufacture License issued by State Bureau of Technical Supervision in 2003. In April 2005 it achieved Special Equipment Manufacturing License of People's Republic of China and has been certificated ISO 9001: 2000 standard. In 2010, Minglong set up a new trading company-Jinan Sanyisan International Trading Co., Ltd,dealing with kinds of construction machineries and building materials. For more than two decades, we have developed the advanced level QTZ40, QTZ50, QTZ63, QTZ80, QTZ100 QTZ125 and QTZ 160 self-telescoping, top slewing and trolleying on horizontal jib tower cranes with Changsha Institute of Construction Machinery of the Ministry of Construction.
Besides tower cranes, we also developed WL160 hoisting machine, SCD200/200 construction elevator, JS350, JS500 and JS750 compulsory twin shaft mixer and associated concrete and stabilized soil mixing station. Meanwhile, we also offer monitoring systems and devices of tower cranes and building hoists: anti-collision system, safety protection monitoring system, wind-speed transmitter, overload limiters, load moment limiter, height, radius and slewing limiters, GPRS remote controlling system, space limit monitoring system, anti-overturning monitor controller, wireless floor call system of building hoist, sensors of tower cranes and automatic leveling device system of building hoist.
In the past 30 years, we always adhere to "Science and technology are the primary productivie forces", established "Crane Research Institute", developed education and training of staff, and introduced a group of talents from colleges and universities, gradually optimizing, updating and upgrading products, and leading the industry. Adhering to corporate spirit of "credit by quality, development by innovation, profit by scale, serve customers whole-heartedly", we try our best to meet customers' demands. We have set up many marketing offices and agents at home and abroad!
