Tower Crane Steel Structure, regarded as the main parts of tower crane, refers to the tower crane jib, tower crane counter jib, tower head, tower crane Telescoping Cage, tower crane turning table,tower crane pull rod, tower crane Mast Section, tower crane Fixing Angle, ect. Steel Structure is made of steel, which fits the name.
Tower crane jib is a metal lattice structure of a normally triangular section, whose main mission is to provide the crane with the necessary radius or range. It is also called a jib. Like the mast, it usually has a modular structure to facilitate its transport.
The Anchorage Frame secures the tower crane mast to a structure or framework and provides stability when the tower crane is under load or experiencing wind forces.
The hook is the main load-bearing component that hauls loads. It is attached to a trolley that allows the hook to raise and lower, as well as move towards and away from the mast.

The 3401A/B stirrer is an important equipment for the oxo synthesis reaction of this plant's octanol plant. Some time ago, its sealing temperature was obviously high, which caused a great pressure on stable high-load production! Faced with special circumstances, the workshop contacted the competent authorities to discuss solutions, but also started special measures such as regular temperature measurement and enhanced inspection, and actively sought to completely solve the problem of the high temperature of the 3401A/B, especially the new B replacement.
Wang Changyi, director of workshop equipment, compared the structure of the oxo reactor octanol reactor stirrer. For the new device, the lack of cooling water coil in the agitator seal, the cycle of sealing white oil is relying on thermal power to self-circulation, cycle force and speed are very Small, only to achieve a certain temperature (relatively high) to be able to cycle, and other characteristics, found that the 3401A / B self-circulating white oil tubing is too thin, taking into account may be due to lack of 3401A / B machine seal itself, B station may be mechanical seal friction pair Pre-tightening force is too large, resulting in the accumulation of heat generated by the two pairs of wear pairs in the machine seal during operation. The heat of the sealed white oil self-circulation alone cannot be taken away in time. Therefore, it is decided to adopt a method of cooling the machine cover by watering!
After this measure is adopted, although the purpose of reducing the sealing temperature can be achieved, a large amount of water is virtually wasted, which is detrimental to safety, environmental protection and energy conservation. What can be done? As a result, equipment personnel started to use their brains to machine and install a precision fixture on the existing machine enclosures. The two halves were fixed with bolts, the fixtures were hollowed out, and the inlet and outlet ports were connected with cooling water. The heat is removed by cooling water circulation.
Through the use of observation for more than a month, the fixture designed by the workshop has received good results. Not only the cooling effect is good, but also the circulating cooling water can be recovered. Both environmental protection and energy saving can serve two purposes.
Qilu II's innovative ideas to protect key equipment
For some time, the second fertilizer plant of the Qilu branch of the butyl octyl alcohol plant in the special period of the end of the operation of the device, use their brains, innovative ideas, focus on special equipment for a special period of special protection, maintaining the stability of the device, high load run.
