Structure drops.
Background technology
Crane refers to more action hoisting machineries of vertical-lift in a certain range and horizontal carrying heavy goods.Also known as day
Vehicle, hanging, crane.Wheel-mounted crane is mainly characterized by：It travels driver's cabin and is combined into one with lifting control cabinl pulpit, is by crawler belt
Crane develops, and the crawler belt of walking mechanism and mobile holder part are become the chassis for having tire, overcomes crawler belt lifting
The shortcomings that machine creeper tread road pavement damages, belongs to material carrying machine.Bridge crane is crossbearer in workshop, warehouse and material
Field overhead carries out the lifting equipment of material handling.It is located at due to its both ends on tall and big concrete column or metallic support, shape
Shape is like bridge.The crane span structure of bridge crane along be laid on both sides it is overhead on track it is longitudinally running, can make full use of below crane span structure
Space handling material, do not hindered by ground installation.It is a kind of hoisting machinery that use scope is most wide, quantity is most.It rises
It is to do intermittent exercise to reset the work characteristics having, i.e., the actions such as feeding, migration, unloading is corresponding in a working cycles
Mechanism is to work alternatively, and crane develops and in the market using more and more extensive.Due to not having to supporting leg lift heavy and lift heavy
Often there are some accidents in traveling, and the speed of traveling is also fast compared with crawler crane；Operation is stable, lifting capacity is big, can be in specific model
Enclose interior lift heavy walking.To ensure job safety, the country, which substantially forbids not making a jack, at present carries out lifting operation.Crane is mating
Include phosphorized coating steel wire rope, galvanized steel wire rope and bright wire rope using steel wire rope kind.
At present tradition lifting equipment supporting leg be fixed structure, when in use there are it is certain the defects of, first, structure
Complexity, installation is inconvenient, and overall structure can not achieve lift work, and stability is poor when encountering the gradient, and drop can not obtain more
It mends, there are some potential safety problemss when causing to run；Secondly, some occurred currently on the market have the supporting leg of elevating function,
For its structure setting using the formula processing that fixes again after lifting, lifting gear uses single equipment, and lifting is promoted and support degree
Limited, lifting space is limited, and clearance space adjusts deficient in stability；Again, traditional lifting landing leg occupied space is larger, mostly
Top is set, and overall structure space accounting is larger, is influenced the space availability ratio of top and side, is caused certain inconvenience.
Therefore, production is a kind of simple in structure, easy to operate, and work and operation high efficiency are high, stable, and dynamics is made
By force, lifting space is big, and service life is long, the small crane support lifting structure of floor space, has extensive market prospects.
