2019-08-12

Full hydraulic transmission, electromechanical dual-purpose, safe and reliable work, high efficiency and low labor intensity; each hydraulic system is equipped with a balance valve and hydraulic lock, which is safer and more reliable; the lifting winch uses a normally closed hydraulic brake, and Optional hydraulic hoisting winch; the boom and important structural parts are made of low-alloy steel plate to reduce the crane's own weight and improve the crane function; all the slewing bearings are made of 50 manganese forging materials; all the main parts of the cranes of 6 tons and above are made of XCMG /Dongyue original accessories, such as: main valve, main pump, winch system, slewing system, slewing ring, etc.

The boom is cold-formed, with a rectangular and pentagonal structure, giving full play to the mechanical functions of the material; the boom is flexible with hydraulic cylinders, making work safer and more reliable; night lights are installed to extend the working time; the boom flexibility limit uses a mark Double insurance with alarm; optional front and rear cab, negative arm and three-phase electric work; crane can be equipped with torque display and height limiter; cranes are equipped with radiators, which is more conducive to summer work; hydraulic oil pipeline rubber All the pipes are made of ultra-high pressure oil pipes made of double steel wires, and all steel pipes have been electroplated;

  Slewing ringIt can work normally from -300C to +700C. If users need to get used to lower or higher temperature supports, our company's engineers and technicians can make special plans for you. If the slewing bearing is used in a particularly harsh environment, such as marine climate, dust or abrasive particles (sand dust, cement, coal powder), etc. It is necessary to select special sealing rings, protective devices, and suitable oil passages. Therefore, in order for your support to function normally, it is expected that daily maintenance and protection work will be done.
