The invention relates to a small crane assembling and hoisting process. The small crane assembling and hoisting process is characterized by comprising the following specific assembling and hoisting processes: S1, mounting a lower barrel; s2, mounting a pivotal bearing; s3, mounting a rotary chassis; s4, installing a winch and a hydraulic room; s5, mounting a slewing mechanism; s6, a propeller strut is installed; s7, mounting a cantilever crane assembly; s8, threading and winding a steel wire rope, and pre-debugging; s9, overall hoisting is conducted; the small crane adopts a single-portal-crane single-hook lifting beam integral lifting mode, the lifting mode has very accurate requirement on the gravity center of the whole crane, and the vertical line of two lifting points of the lifting beam passes through the gravity center of a rotary part and the gravity center of a cantilever crane in the same vertical line of a lifting hook and the whole crane structure; due to the adoption of the hoisting mode, the use of hoisting equipment in the hoisting process of the small crane is reduced, the hoisting efficiency is improved, and rapid installation and hoisting of the small crane equipment in a production site are realized.
本发明涉及一种小型起重机装配及吊装工艺,其特征在于:具体装配吊装工艺如下:S1:下筒体安装;S2:回转轴承安装;S3:回转底盘安装;S4:绞车及液压房的安装;S5:回转机构安装;S6:人字架安装;S7:臂架组件安装;S8:穿缠绕钢丝绳、预调试;S9:整体吊装;小型起重机采用单台门机单钩吊梁整体吊装方式,该吊装方式对整机重心要求非常精准,保证吊钩与整机结构在同一垂线内吊梁的两吊点垂线过回转部分、臂架各自的重心;这种吊装方式的使用,减少小型起重机的吊装中吊装设备的使用,提高了吊装效率,实现了小型起重机设备在生产场地的快速安装吊装。
