Line hanging stopper line hanging must have moments, high, horn, walking four stopper, but also hook and reel Insurance insurance. Line hanging between two limiting device was installed, at least when they are no longer close to a distance of one meter, and it will be very prone to accidents. Since the tower structure and the kind of particularity, the corresponding safety device two tons of line hanging price, according to the actual requirements should be as follows: 1 with respect to the safety device of the four tower crane moving mechanism are: torque limiting its , from the weight limiter, slewing limiter, luffing limiter, which increased limiter, large dealers limiter; 2 relative to the tower crane safety device electrical properties are: over-current protection, under-current protection zero is protected. 3. Other: anemometer, bull red, anti-sensing device, lightning protection devices. Walking limit is not derailed rail-mounted crane control to run. Security checks should be carried out crane walking motion test, to verify the reliability of the collision limit. The key part of the reason Cranes single-beam crane line reducer crane single girder crane line reducer oil spill, there will be some failures after prolonged use, such as oil. Crane reducer underwent crane, will lead to decreased efficiency of the equipment line hanging safety regulations, in order to solve the problem, we want to know what causes crane reducer, the following will explain to you the proof crane manufacturer, I hope to help you .: 1 due to the design is unreasonable, such as design no holes or air hole is too small, so that the internal pressure and external pressure imbalance, resulting in oil spills; because the car is running mechanism gear oil pool is the case of the upper and lower, because long Time is running, two boxes Mifengbuyan easily spill joints. 2. mainly the description, the bonding surface accuracy is not because Mifengbuyan and oil spills. 3. improper use of a plurality of closed protection, LED internal pressure is too high, too much oil, the oil level is too high; connecting bolts loose, not tight surface of two boxes.
