Crane bearing and lack of system pressure

Insufficient pressure of automobile crane hydraulic system is mainly due to the overflow valve hydraulic pump,bearing manufacturer failure cause. Truck crane hydraulic system generally consists of two or three hydraulic pump to provide pressure oil system.

  Fuel pump is two, small displacement pump as the outrigger retractable power supply circuit,mobile crane bearing the manual reversing valve outrigger retractable loop is in place, the pressure oil enters through the center of the revolving body connector on the train combined control valve.

  Large displacement pump output pressure oil through the center of the revolving body connector also enters the pressure oil pump output bus combination valve and manipulation of small displacement confluence together for the slewing mechanism, lifting mechanism circuit loop, telescopic crane bearing boom luffing loop and loop injection.

Crane bearing telescopic crane loop and lifting arm luffing loop

• Telescopic crane loop

The hanging arm is composed of basic arm and a telescopic arm,mobile crane bearing a telescopic arm in arm in the basic set. Telescopic boom is controlled by the telescopic hydraulic cylinder and steel wire rope. In order to prevent the hanging arm falling on the mass of the balance valve, a telescopic loop.

• The lifting arm luffing loop

The so-called amplitude hydraulic cylinder is used to change the angle of the boom.( ship loader bearing ) Luffing operation is also required to prevent the drop in weight function, therefore the lazy arm amplitude circuit is also provided with a balanced valve. Failure of truck crane bearing hydraulic system is mainly manifested in the five loop, the most common fault is the system pressure is insufficient and the hydraulic cylinder retracts.

Mobile crane bearing hoisting mechanism brake system

Brake system in the lifting mechanism is arranged on the brake cylinder, so as to turn in a hydraulic motor,agricultural bearings , brake lock lifting hydraulic motor. At the same time in the brake cylinder into the oil passage is provided with a one-way throttle valve, and its role is to enable the brake brake fast, slow release the brake.

  The former is to enable the motor to brake quickly, quickly stopped falling weight. The latter is when the load lifting process again in mid air,mobile crane bearing , avoid heavy weight of the hydraulic motor drag inversion and produces transient downhill phenomenon.

Hydraulic truck mobile crane bearing

Due to the arrangement of the balance valve( marine crane bearing ), so that the hydraulic motor can only have the pressure in the oil inlet of case rotation, so falling will not produce the phenomenon of nod.

  But the leakage of the hydraulic motor of the hydraulic cylinder is much larger than that when the load hanging in the air, although the balance valve is provided with a circuit,agricultural bearings  ,they may still produce the slipping phenomenon.

Hoisting mechanism circuit of mobile crane bearing

The lifting mechanism is the main implementation mechanism of crane, winch is driven by one or two large torque hydraulic motor.( ferris wheel bearing ) Motor forward and reverse control by a manual three position four way reversing valve.

  The rotational( rotary bearing ) speed of the motor, namely the lifting speed can be adjusted by changing the speed of the engine. In the back of the oil motor decline on the road with the balance valve,ship loader bearing used to prevent the free falling weight.

Slewing mechanism circuit of mobile crane bearing

The slewing mechanism ( slewing bearing manufacturer )adopts the hydraulic motor as the actuator. The hydraulic motor through a speed reducer to drive the turntable, the turntable speed is low, generally 1 ~ 3r/min. To obtain a left turn, right turn stop,mobile crane bearing three different conditions through a three position four way manual reversing valve.

Outrigger retractable of hydraulic truck crane bearing

Because the bearing capacity of the Automobile Tire Co., during the lifting operation must put down the leg, make tire overhead, and the car must be the away leg. There are two legs before and after the crane bearing , each leg were controlled by the manual reversing valve, the legs with horizontal and vertical hydraulic cylinder hydraulic cylinder (mobile crane bearing ).Vertical hydraulic cylinder with bidirectional hydraulic lock, to ensure that the leg is reliably locked, prevent the lifting operations occurring in the process of Soft Legs phenomenon or in the driving process of hydraulic legs automatically falls,ferris wheel bearing .

Full hydraulic mobile crane bearing

Full hydraulic truck crane is a kind of truck crane slewing （crane bearing ), luffing, full hydraulic transmission and hydraulic operation.
  The outrigger retractable, slewing mechanism, the five part telescopic crane lifting mechanism, and the lazy arm amplitude are the hydraulic drive, stepless speed regulation( high speed bearing ), and according to the need to make any part of a separate action,mobile crane bearing also can be in the implementation of components is not full, the implementation of components of each series of any group of contract action.

Reflections on the ferris wheel project

For the Henri Vander Knokke and his colleagues, this is a very exciting experience, he confidently said，from the project, we learned a lot of things, and the experience will be well applied in the future.

  Schaeffler Group in Berlin and Orlando Ferris wheel project also got orders. Customers like Schaeffler Everything is contained therein., worry free packaging services, thanks to during operation we can provide a technical support for the production and design service, which is provided by the Schaeffler subsidiary of --FAG company.

  All members of the team project has a dream: to Beijing to really enjoy a world's tallest ferris wheel travel. This is what they deserve.

All the casual products,behind which have a team in unremitting efforts. So this is also so for LYHY bearings，take the quote of the film ,Our lives are not our own, From womb to tomb, we are bound to others.It is these connections, or effort, composed of a bearing universe.
