Description
[technical field]
The present invention relates to a kind of fixed crane.
[background technology]
The common fixed crane in existing market has the disadvantage in that
There is back-roll phenomenon in the first, steel wire rope, rope service-life is shorter；
The second, meeting reverse-winding during grab bucket operation, grab bucket operation lifting velocity is fast, and impact is big, there is zero load and heavy burden
Lotus situation alternately, owing to there is back-roll, strand easily beaten by steel wire rope, inadaptable grab bucket operation；
3rd, the front leg strut of man-like shelf wears hinge, rear support leg arm-tie and turntable together with jib with turret assembly
Wearing hinge, can there is gap in this articulated manner, generation is rocked, and rigidity is poor；
4th, there is intersection in turret assembly arrangement space, owing to man-like shelf front leg strut is arranged in turret assembly front portion, herringbone
Frame rear support leg is arranged in again in the middle part of turret assembly, and lifting amplitude-change mechanism needs to carry out interference checking.Single lifting mechanism is used for suspension hook,
Double lifting mechanisms are used for grabbing bucket, and the structure of man-like shelf limits freely arranging of lifting mechanism, need to carry out detailed every time
Interference checking, bothers very much；
5th, at load power taking pulley, back-roll is formed: load power taking pulley is arranged on man-like shelf foreleg centre position, steel
Cord from reel out after, load power taking pulley cause man-like shelf head leading block, then cause jib head, steel wire rope exists
Back-roll can be formed at load power taking pulley；
6th, single-point compensates, and during luffing, the horizontal difference of height of suspension hook is general with jib stress balance, during design, as wanted to obtain
Obtain preferable horizontality, then need suitably to sacrifice jib stress equalization.
The present invention is namely based on what this situation was made.
