    摘要： In one aspect of the invention, a telescopic boom includes a plurality of boom sections, and a sheave assembly disposed between two adjacent boom sections. The sheave assembly includes two sheave assembly sets. Each sheave assembly set includes a plurality of sheaves having different diameters. The plurality of sheaves is arranged abreast along a lengthwise direction of the adjacent boom sections and the diameters of the plurality of sheaves increase successively along the lengthwise direction of the adjacent boom sections. Each sheave is wound with one or more cables. The invention also discloses engineering machinery having the telescopic boom.

    摘要： A vehicle crane having a superstructure with a jib system including a main jib mounted in a luffable manner on the superstructure, with a jib head and a luffable additional jib and at least one luffing support supported in the region of a luffing axis of the additional jib. At least one guying support of the jib system is arranged in such a manner that a tensioner starting on the one hand from the superstructure and/or from a counterweight and connected on the other hand to the additional jib is guided via the at least one guying support and the at least one luffing support. A main jib extension is incorporated between the jib head and the additional jib with the at least one guying support supported at the main jib extension to obtain a longer design of the jib system with the highest possible permissible bearing load.

    摘要： A multi-sectioned, telescopically extending column. This invention includes an extension mechanism to extend the column and support the column sections during extension, and a locking mechanism to lock each column section to the next when the column reaches its extended position. The column is particularly well suited for use as a crane boom, where individual boom sections are nearly fully extended each from within the other to minimize overlap between adjacent sections and reduce dead weight resulting from such overlap.

    摘要： A crane capable of being employed as a back-hoe for digging, gathering, collecting or recovering bulk materials, such as soil particles or the like, characterized by a boom assembly including a plurality of telescoping boom segments pivotally supported on a rotatable base and including a plurality of flexible tape members interconnecting the segments and adapted to be selectively tensioned for imparting selective rectilinear displacement to the segments for thereby telescopingly elongating and contracting the boom assembly, a feature of the invention being a furlable tape adapted to be flattened and wound about a tape take-up drum as the boom assembly is contracted and deployed into an elongated tubular conduit extending axially between the opposite ends of the boom assembly as it is elongated, whereby a variable length fluid conduit is provided between the distal end and the base of the boom assembly.

    摘要： A means and technique are disclosed whereby a crane boom or other outrigger device which is mounted on an anchorage to be pivoted into an operatively inclined position relative to the horizontal, may be comprised of a pair of elongated boom sections that are relatively reciprocably engaged to be extended and retracted in relation to one another along the length of the device while it is in the operatively inclined position thereof. According to the invention, the means for raising and lowering the device to and from the operatively inclined position thereof, and supporting it in said position, include a pair of pendants that are operatively interconnected between the anchorage and the aforesaid boom sections, and each individually operative to assume support of the device when in tension. In addition, there are control means connected to one of the pendants which are operative to shift the support of the device from the one pendant to the other, and vice versa, by altering the tension in the aforesaid one pendant so as to pivot the device either toward or away from the horizontal when the other pendant is taut.
