摘要： The disclosure relates to a crane, in particular a mobile lattice boom crane, having an upper carriage, a tiltable boom articulated to the upper carriage and a tiltable bracing frame articulated to the upper carriage. The bracing frame can be connected to the boom via a bracing and is connected to the upper carriage via an actively adjustable bracing cable, wherein the bracing cabling comprises a bracing cable mounted on a cable winch so that it can be wound up and unwound. According to the disclosure, the crane comprises a variable-length traction element, via which the bracing frame can be connected to the boom in an articulated manner and which is designed to exert a tractive force on the bracing frame in the direction of the boom. The disclosure also relates to a method for moving a crane according to the disclosure into a braced operating position.

摘要： A method and apparatus is disclosed for controlling the angle of a pivoted, pendant supported extensible boom and the mast-boom angle between working positions and a transport position. The structure for controlling the angle includes a wire rope driven by a winch and trained over a boom supporting hoist and over a pendant take-up hoist which includes a floating sheave assembly connected to an extensible portion of the boom by a fixed length pendant. Another fixed length pendant determines the mast-boom angle when the boom is in working position, and a floating sheave stop is pivoted to the mast in position to cradle and/or abut a portion of the floating sheave assembly for enabling complete control of the mast when moved between its transport position and working positions relative to the boom.

摘要： The present disclosure discloses an operating method of a wind power jib of a crane and a crane, and relates to the field of engineering machinery. The method includes the following steps: rotatably connecting a main boom and a wind power jib; overturning the wind power jib to a first preset position by using a traction means of the crane; contacting a cushioning member with the wind power jib provided at the first preset position; further drawing the wind power jib to overturn to a second preset position; releasing the traction means, such that the wind power jib overturns automatically under the effect of self gravity and a cushioning member until the wind power jib is overturned in position.

摘要： A telescopic crane, includes a substructure, a superstructure rotatably mounted onto the substructure, a counterweight and a telescoping boom structure which includes a main boom slewable about a luffing plane. The main boom has a boom base and at least one telescope section received in the boom base and displaceable between retracted and extended positions. At least one guy support is mounted to the boom structure and connected to a guy rope which extends substantially longitudinally in the direction of the boom structure. The guy support is oriented with respect to the luffing plane at an inclination which is so selected that a lateral load acting on the boom structure is partially or entirely received by the guying.
