1. High safety ratings ensuring reliable operation.
　　The tower cranes are deployed with high quality and effective safety devices, including a hoisting height limiter, trolley travelling limiter, moment limiter, lifting load limiter, slewing limiter, trolley protective rope (slipping protective) protection devices and trolley shaft anti-breakage devices, etc. The tower crane has high reliability and accuracy, ensuring its safe operation.
　　The hoisting rope adopts non-rotating steel wire ropes, which can prevent knotting of the steel wire rope during use, which can be dangerous and costly to fix.

2. High quality configurations make for smooth and durable use.
　　Electrical components and outsourcing accessories of the tower crane are supplied by domestically famous brand such as Schneider. The high quality components ensure the tower crane operates smoothly reliably, safely, and energy efficiently.
　　Materials of the tower crane are Q235 and Q345B supplied by Baogang Steel Company and Angang Steel Company, which have high weight bearing capacity and long service expectancies.
　　The railings of the platform and all small components of the mast are all galvanized, ensuring a service expectancy of 10-15 years.
　　The overall tower cranes all have whole shot peening treatment, the rust cleaning level reaches Sa2.0-2.5 standard. Painting is classified into painting and baking techniques. Clients can freely choose according to their needs. A whole painting can meet 5 years of continuous use.
　　The hoisting mechanism and the slewing mechanism both adopt variable frequency technique, making it operate smoothly and free of shock. Meanwhile, the maintaining cost is reduced and life expectancies of the structure and the transmission components are prolonged.
3. Various working modes and a wide scope of operation.
　　By changing, reducing and increasing some of the components and auxiliary devices, the tower crane is able to switch into fixed type, attached type and other kind of working modes, thereby meeting various user's requirements.
　　The lifting jib has multiple length combinations, increasing the working space and working scopes.
4. Simple and easy to use design.
　　The tower crane adopts hydraulic jacking system, enabling the mast rising or going down in accordance with the building height.
　　Customers can freely choose among angle steel, square tubes or chip type as the materials of the mast.
　　Independent cab is situated on the side of the tower crane's mast, providing good horizons for the operator. Air conditioner in the cab can also be provided as the customer requests, which maintains a comfortable environment for the operator.
