[Chemical composition] Natural pure magnesium endmembers have not been reported. [Crystal structure] orthorhombic system; [Form] Crystals are often columnar and plate-shaped, and the common simplex is {210}, {100}, {001}. Fibrous amphibole is called amphibole asbestos . [Physical properties] white, gray or green; glass luster. The cleavage {210} is complete with an angle of 125°30'. The hardness is 5.6 to 6, and the relative density is 2.85 to 3.57. [genesis and occurrence] is a rock-forming mineral of some chip rocks. [identification characteristics] morphology, cleavage, color, produced in the chip rock. [Main use] See the Asbestos family asbestos. A load moment indicator is an instrument used in determining whether a certain load could be carried by the Tower Crane
or not. When the operator runs the tower crane, load moment
indicator could show the comprehensive working condition of the tower
crane, which help him run the tower crane safe and effective.
Models of load moment indicator: RC-A5-I load moment indicator, RC-A5-I Tower Crane Load Moment Indicator, Load Moment Indicator CXT30.
When more than one set of tower crane work at the same time, Tower Crane Anti-collision Safety System will be required. A multi-function Safety System for Tower Crane 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 in operator cabin and online. In the meantime it combines functions including black box, anti-collision & zone protection.The system is applicable to various types of level-jib and luffing tower cranes. It adopted the most advanced ARM embedded intelligent microprocessor technology, high precision digital azimuth sensor, weighing sensor, angle sensor.which greatly enhanced data processing capability with higher precision and higher stability.
