What is the difference between a tyre crane and a crane
Wheel crane: rotation of wheeled chassis walking arm crane. x0d tyred crane is installed in the hoist mechanism of heavy-duty tires and axles composed of special chassis, a full slewing crane, the superstructure and crawler crane basic same, in order to guarantee the stability of the installation job opportunity and the crane is equipped with four retractable leg. In a flat on the ground can be small lifting weight lifting and no leg hanging lower speed. It consists of two parts, get on the bus and get off the bus. Get on the bus for lifting operation part, movable arm, lifting mechanism, luffing mechanism, balance weight and turntable, etc.; Get off to support and walk part.
Lifting weight, lifting height, amplitude, load moment and the weight of the whole machine. Wheel crane rated lifting weight by movable arm strength and overall stability limits, according to the amplitude change, in order to prevent overload must be equipped with a torque limiter, crane because of the high speed, flexible, automobile chassis and parts supply convenient wait for an advantage, especially the telescopic jib type crane, developing very quickly. The tyre crane is the further development of the direction of the mobility and cross country ability. Multilateral special-shaped section telescopic boom, box radiant chassis, activity type counterweight, the new wheel crane appear constantly. x0d tyred crane development trend is: large-scale, efficient, safe, and reduce weight, further improve the lifting driving performance and maneuverability. x0d truck crane, truck crane is in a normal car chassis or special automobile chassis of a crane, its driving cab is separated from lifting control room Settings. This kind of crane is the advantage of good maneuverability, move quickly.
Get off for the bearing and walking part. With the rotary bearing connection between on and off. When hoisting generally need to put down the leg, increase the bearing surface, the fuselage leveling, and to ensure the stability of the crane. According to the form of the chassis divide into two kinds: tyre crane and crane the former adopts special chassis, body, move flexible operation; Latter lifting operation part is installed on the chassis, body is longer, has a truck driving performance, it can quickly transfer or with single car fleet. x0d derrick structure form has two kinds of truss arm and arm extension. The former use transformer, wire rope pulley block long arm folding or extension, its length is bigger; The latter section for box section telescopic boom, with telescopic hydraulic cylinder and transformer. Driving state due to the small overall dimensions, meet the needs of the rapid transfer site. Working mechanism can be mechanical, hydraulic and electric. Hydraulic with compact structure, convenient operation, easy to control and realize overload protection, etc. Wheel crane are normally used for loading and unloading heavy and installation, the weight is small, can not play leg homework, even walking on load. With good mobility, transfer the characteristics of convenient, applicable to liquidity operations, widely used. The basic technical parameters for
