Beijing Construction Machinery Factory launched the new tower crane QTZl60

Recently, in order to adapt to the market and meet the needs of different customers, the technical engineering department of Beijing Construction Engineering Machinery Factory has developed a new tower crane QTZl60 after more than three months of technical research. The tower crane has a boom arm length of 60 meters, an arm tip weight of 2 tons, and a rated lifting torque of 160 tons. The hoisting mechanism adopts the two-speed winding motor under the PLC programmable controller, which has higher control precision and stronger reliability than the original tower RCS mechanism; the slewing mechanism uses the torque motor, compared with the original tower series electromagnetic coupling The design has a low failure rate: the car uses frequency conversion technology to make the operation more stable. Its biggest advantage is that the working coverage is increased to meet the needs of mid-rise construction.


It is reported that the tower crane has completed the design of the pattern, the overall design calculation, the calculation of the main load-bearing steel structure, the tooling design, and the process estimation, and the preparation work before the trial production is underway.

Internal Rubber Mixer mainly used for rubber molding and mixing of rubber, is a machine equipped with a pair of specific shapes and relative to the rotation of the rotor, adjustable temperature and pressure in the sealed state of the polymer material on the plastic and mixing of the mechanical, mainly composed of the mixing chamber, rotor, rotor seal device, feeding pressure material device, discharge device, transmission and chassis and other components.

This machine is suitable for EVA, rubber,synthetic rubber,hot melt and all kinds of chemistry raw material

to mix ,mediate and disperse, and then put into the mass production.

75L kneader mixer

Hard tooth gear reducer with well-design structure, low noise, high efficiency and long service life. The mixing shaft is made of nickel & chrome alloy steel. The high abrasion part is additional welded with imported anti abrasion welding rod, then electroplating with hard chrome which is more durable.The main mixing chamber is whole set casting by high anti abrasion alloy steel, after special dealing then electroplating with hard chrome.The anti leakage unit of side wall is made of high-tech material which is wear-resisting and easy to maintain. [M" shape of the pressure gland which make the mixing more thorough and even.  The main motor ampere meter is installed in the electrical control panel, under normal running, when the pressure of the mixing chamber is too big, the current exceeds the set value, the connector will automatically adjust the gland`s up and down via the magnetic valve to remit the pressure of the mixing chamber. The mixing chamber is bigger, the diameter of the air cylinder is bigger and gear reducer is also bigger, which enhance the mixing effect,save mixing time and also save the cost.
