Chapter three The Hydraulic pumps hoist is in popular important position that engages in of the thing 3.A hoist is here the prevailing industry of the thing has very great function too The supplies Hydraulic motors--->hydraulics parts have been carried into a importance component that the mankind produced the activity, the developing history that that was more than 5,000 years ago. With the enlargement of the production scale, the improvement of the automatic intensity, the hoist carrying the important apparatus as the supplies applies in modernized production process wider and wider, function is greater and greater, the requirements for hoist are higher and higher. The hoist is going through an enormous change. 3.1.1.Maximization and melting special-purposely Because process supplies load and unload, carry proportion of expense increase gradually, impel the demand for the large-scale or high-speed hoist to increase constantly. Weight arises bigger and bigger, the working pace is higher and higher, and the requirement for putting forward higher in energy consumption and dependability. The hoist has already become the important links in automatic production procedure. The hoist should be not only easy to operate, easy to safeguard, but also security is on good terms, dependability should be high, demand to have excellent durability, have no trouble, maintaining and using economy. A most heavy one swim hoist get up weight reach 6, 500t, heavy track hoist get up weight up to 3 most in the world at present, 000t, heavy bridge type hoist get up weight 1, 200t, container bank loading bridge most loud running speed of car already reach 350m/min most, pile buttress hoist most large running speed 240m / min, with to get up, rise pace up to 100m/min hoist garbage disposal. The industrial mode of production and variety of the user's needs, make the market of the special-purpose hoist expand constantly, the variety brings in constant renewal in too, meet the special need with the characterized function, give play to the best utility. Special-purpose hoist such as metallurgy, nuclear power, papermaking, garbage disposal, explosion-proof, antiseptic, insulating hoist and the functions of the railway, vessel, special-purpose horse of Germany of Germany develops the special-purpose hoist that a kind of plane maintained in one dose of companies, have opened the sale on the international market.

Install flexible conduit of many festivals under the jack-up car, maintain the platform and link up with the plane, and can rotate from all angles. Can be enabled and maintained taking the post as a position of the platform arriving aircraft through displacement, Hydraulics Parts---->Kato genuine cranes parts rise or fall and rotation of conduit of cart and car, carry on maintenance and repair of the plane, extremely swift and convenient. { Page Précédente } { Page 12 à 15 } { Page Suivante } |
