Fire crane

Crane definition, a way to move the telescopic tubes, used in petroleum, chemical liquid handling wharf, tube media such as oil and water. Common specifications DN50 / 80/100/150 / petrochemical industries ranging from the crane is in the process of fluid handling equipment. It uses a rotary joint connection with rigid pipes and elbows up, to be achieved between the train trestle storage tank car and pipeline transport liquid medium activity equipment to replace the old hose connection, with high security, flexible resistance and long service life. Products meet GBJ74-84 "oil depot design" standard, is an ideal transceiver oil process special equipment, can be widely used in the chemical industry and other industries receive all kinds of liquid raw materials. Crane points: car loading crane, crane unloading trains, aircraft loading and unloading crane, crane barreled tube. Rail, road crane unloading oil is mainly used for fluid handling equipment railroad tank cars and tank cars highway job. From the loading and unloading type can be divided into the bottom of the jacket loading. There can transport medium crude oil, gasoline, diesel and other petroleum products; but also transport of concentrated sulfuric acid, liquefied petroleum gas, ammonia, propylene, propane, dimethyl ether, methanol, benzene and other chemical products. Crane mainly by fixed, rotary, operations, balance and other institutions and tubing components. Among them, the slewing mechanism (rotary joint) is well-made with forged steel, built-in re-row ball bearings, stainless steel special seals, it rotates flexible, reliable sealing performance and durability. There counterweight balance system, torsion, compression spring, tension spring and screw balance, as well as hydraulic and pneumatic type, can be operated with a small force.
