    Crawler cranes range in lifting capacity from about 40 to 4,000 long tons (44.8 to 4,480.0 short tons; 40.6 to 4,064.2 t) as seen from the XGC88000 crawler crane. [58] The main advantage of a crawler crane is its ready mobility and use, since the crane is able to operate on sites with minimal improvement and stable on its tracks without outriggers.

  4. Lattice boom crawler crane - Wikipedia

    en.wikipedia.org/wiki/Lattice_Boom_Crawler_Crane

    A lattice boom crawler crane is a crane that gets its name from the W or V shaped lattice design of the boom. The benefit of this design is that it decreases the total weight while still providing maximum support for heavy loads. Other lattice boom crane parts include the crawlers, hoist, cab, sheaves, and wire ropes.

    Generally, the 3 pumps used in excavators consist of 2 variable displacement piston pumps and a gear pump. The arrangement of the pumps in the excavator unit changes with different manufacturers using different formats. The three main sections of an excavator are the undercarriage, the house and the arm. The boom, the front part that is ...

  6. Hydraulic pump - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_pump

    Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a ...

  7. Hydraulic machinery - Wikipedia

    An exploded view of an external gear pump. Hydraulic pumps supply fluid to the components in the system. Pressure in the system develops in reaction to the load. Hence, a pump rated for 5,000 psi is capable of maintaining flow against a load of 5,000 psi. Pumps have a power density about ten times
