Description
Technical field
The present invention relates to crane mechanical field, and in particular to a kind of fluid pressure type support lifting based on hydraulic cushion principle
Machine.
Background technology
Crane refers to many action hoisting machineries of vertical-lift within the specific limits and horizontal carrying heavy goods, also known as hangs
Car.Wheel-mounted crane is mainly characterized by：It travels driver's cabin and united two into one with lifting control cabinl pulpit, (is carried out by crawler crane
Band is hung) develop form, the chassis that the crawler belt of walking mechanism and mobile holder part are become to have tire overcomes crawler crane
The shortcoming that (crawler crane) creeper tread road pavement is damaged, belongs to material carrying machine.
The work characteristics that crane gear has is to do intermittent exercise, i.e., feeding, migration, unloading etc. in a working cycles
The corresponding mechanism of action is alternation, crane development commercially and using more and more extensive.Due to without supporting leg
Often there are some accidents in lift heavy and lift heavy traveling, and the speed of traveling is also fast compared with crawler crane (crawler crane)；Operation is stable, rise
