The invention discloses a pulley hoisting device and a crawler crane. The pulley hoisting device comprises an arm head pulley mechanism, a lifting hook pulley mechanism and a lifting hook mechanism connected with the lifting hook pulley mechanism, the arm head pulley mechanism comprises one or more arm head pulley block units which are arranged in parallel; each arm head pulley block unit comprises a first longitudinal pulley block and a first transverse pulley block which are connected up and down; the hook pulley mechanism comprises one or more hook pulley block units which are arranged in parallel; each hook pulley block unit comprises a second transverse pulley block and a second longitudinal pulley block which are connected up and down; and each arm head pulley block unit corresponds to the lifting hook pulley block unit. The transverse length of the device can be shortened, and the construction requirement of a small space is met; larger load capacity can be borne; the stress bending moment of the pulley shaft can be reduced, so that the diameter of the pulley shaft is reduced; therefore, the diameter of the steel wire rope is reduced.
本发明公开了一种滑轮吊载装置及履带起重机,包括臂头滑轮机构、吊钩滑轮机构以及与吊钩滑轮机构连接的吊钩机构;臂头滑轮机构包括1个或多个并联设置的臂头滑轮组单元,臂头滑轮组单元包括上下连接的第一纵向滑轮组和第一横向滑轮组;吊钩滑轮机构包括1个或多个并联设置的吊钩滑轮组单元,吊钩滑轮组单元包括上下连接的第二横向滑轮组和第二纵向滑轮组;各臂头滑轮组单元和吊钩滑轮组单元对应设置。本发明能够缩短装置的横向长度,满足较小空间的施工要求;能够承担更大的载重量;能够减少滑轮轴的受力弯矩,进而减小滑轮轴的直径;能够降低钢丝绳的拉力,进而减小钢丝绳的直径。
