Anti-Sway Crane

It is known that swaying is a big problem for safety and efficiency operation of overhead cranes and gantry cranes. To this end, Yuntian develop advanced crane anti-swing control system for the cranes through the establishment of the precise load swing movement mathematical model. This anti-swaying system of cranes controls the traveling speeds of the crane and trolley to eliminate load swing by 95%.

RC-A11-II integrated load moment indicator with anti-collision&zone protection system and remote online monitoring system.It indicates real time working states of tower crane and tower crane group both on tower crane and on the online computer.The system adopted full-touch mode of operation,and the most advanced ARM system,higher integration,greater precision data acquisition.The system can show the operator and manager the most comprehensive working states of tower crane in operation. At the same height:the system will auto detect and deal it with if any interference within running radius of slewing mechanism. At the different height:the system will auto detect and deal it with if any interference between higher hook and lower slewing mechanism. The system can set up to 10 different protection zones,prohibit flying over sensitive areas such as power lines,schools,highways,building etc.Try to achieve max.working area of tower crane within ensuring tower crane safety.

his anti-collision device is a tower crane safety system. It has the following functions: CXT/800 system protection Tower crane Anti-collision protection If tower cranes are with the same height, this system can control and handle it effectively, once detecting that the running jibs interfere with each other automatically. While not with the same height, this system can also work effectively once anticipating the hook or cable of the higher tower crane may collide the jib or counter jib of lower one. Zone(obstacle) anti-collision Due to the complexity of some sites, the system can automatically and effectively determine up to 10 prohibited zones in which the hook or jib are not allowed to operate. Boundary protection Complicated environment usually exists around work site. The CXT/800 system can be preset with a up to 30-point boundary protection area in which the operating or over-flying of hook is not allowed. It can effectively prevent accidents from happening. Pre-alarm/alarm and control CXT/800 system allows the operator to work at maximum efficient way and optimize the use of Crane. Once monitoring the pre-set data for possible collisions in crane interference area and over-flying of sensitive areas, there will be pre-alarm and visual and audible alarm and the system will stop the maneuver automatically to maintain a safety margin.

During the overhead crane running, due to the inertia, the lifting hook ( or other spreaders) will swing with overhead crane move, this swing is not conducive to crane hoisting operations. Anti-swing device can help the overhead & gantry crane to avoid the impact, bow we suggest the electronic anti - swing to instead of mechanical anti-swing device. Overhead crane electronic anti-swing control system consist of sensor, programmable controller, drive and bridge crane system, uses digital ac variable frequency speed control device. Working principle Its working principle is: the sensors and detection element collect the running information, such as spreader swing angle, the angular velocity and so on, microcomputer internal programmable controller will process these detected information, then will provide the best control parameter to the vehicle velocity modulation system ( drive device) to control the electric hoist trolley running direction and speed, limit the spreader and load swing angle to the minimum, then achieve anti-swing and eliminate swing purpose. Together with electric trolley running, electronic anti-swing achieve the effect of reducing swing by controlling the corresponding input force, can achieve automatic control, compared with the mechanical anti-swing device, no need drivers operating experience, almost can unmanned operate.

Explosion-proof capacity of all the motors and electric equiment accord with gb3836.2-2000.The qb 5~50/10t double beam explosion proof overhead crane has passed the experiment of the national supervision and the performances accord with jb/t5897-1991. The explosion-proof mark are exdiibt4, exdiict4.Qb overhead explosion-proof crane with hook is applicable to the workshops where the explosion-conduction is lower than 2b or 2c, burning point is highter than t4, and is applicable to section 1 or 2 ( for more details, please check gb3836.1-2000)this tyble is generally controlled on the gound, but can be cab-operated when needed. The work classification is interdict.The crane has obtained explosion-proof certificate after passing examinations by units designated by the government to test explosion-proof products. The explosion-proof marks exd ii bt4 and exd ii ct4 respectively. This qb 5~50/10t double beam explosion proof overhead crane is generally controlled on the ground, but control from the driver's cabin also allowable. The working grade is intermediate.

RC-A5-I load moment indicator is applicable to all types of level-jib and flat-top tower cranes.The system adopts 51 single chip and 5 inch LCD,it indicates real-time working state of tower crane and record,once overload,it will cut off circuit and prevent dangerous operation,ensure crane safety operation. It provides the operator with actual and correct information on working states of tower crane on as follows through LCD:actual load,rated load,hook height,hook amplitude,slewing angel and wind speed etc.If the load reaches 50% or 80% specified moment,it will pre-alarm.If it reaches 105%,it will alarm and prevent the trolley automatically from moving outward and the hook from lifting upward.

RC-108 mobile crane load moment indicator adopts PAT technology from Germany,which available for mobile cranes in complex conditions.The system has press buttons for related working conditions.The clients can selected different working conditions to achieve safety protection on mobile crane.It also has functions of pre-alarming,overheight,overload,alarming.The clients can easily to judge the overload and overheight as per operation status.

RC-FS08 are used in the meteorological observatory (station), chemical industry, power station, Industrial and mining establishment to record the wind's traveling schedule and observe instantaneous wind speed installment. The indicator can realize the equipment wind speed instruction digitally and automatically. And it is essential sophisticated equipment for some modern equipment. Micro-anemometer is composed with STC12C2052 single-chip and its related periphery line, the display screen adopts two windows high brightness eight nixie tubes which can display currently actual wind speed and wind scale separately.
