According to incomplete statistics, nearly 5,000 people are killed each year in China due to the falling of hanging baskets used for urban building maintenance. However, this kind of operation has basically disappeared in developed countries and has been replaced by aerial work platform.
In recent years, aerial work platform has become a common equipment for site construction, and the small and exquisite scissor aerial work platform has become an "marvelous object" for indoor construction.
In view of the increasing market demand for scissor-type aerial work platforms, it is imperative to design a fast and batch linear production mode for scissor-type forklift trucks. The project of "Linear Process Transformation Project of Shear Forklift Aerial Work Platform" carried out by Runshare Heavy Industry has formed a controllable production line through the construction of linear production line, which can comprehensively improve the production efficiency and quality stability of shear forklift products.
GTJZ series scissor type aerial work platform production assembly line mainly consists of the following three parts:
Assembly area: pre-assembly line is built in the assembly area, and the assembly area is formed after the components are pre-assembled, and consists of the assembly area and the pre-assembly area. General assembly includes M1 chassis assembly, M2 fork assembly and M3 platform assembly. Pre-installation can be divided into battery side pre-installation, small pre-installation, hydraulic side pre-installation.
Test area: general test, function test, overload test and climbing test of assembled products.
Final inspection area: it is divided into the manufacturing department to conduct all inspections on the products after the assembly of the main assembly line is completed, and the quality department CPA to conduct all appearance and main function inspections on the products again after EIA inspection is qualified.
Assembly Process of GTJZ Shear Fork Type Aerial Work Platform;
From the process flow chart, it can be seen that in each assembly process, a number of raw materials are assembled into parts on line, which are then distributed to the next process to continue assembly. In each process, employees are required to carry out self-inspection and mutual inspection. In case of abnormal conditions in the assembly process of products, defective raw materials are selected separately, and then assembly is continuously transferred to the downstream process. Its advantages mainly include:
(1) Timely discovery of raw materials and assembly quality defects in the assembly process to reduce rework costs;
(2) In the process of assembly found problems in product design or manufacturing process in time, in the product completed assembly
Before the discovery of quality defects;
(3) Provide more information about defects for online rework personnel;
(4) Provide more quality information. Through the quality control of each assembly line of each shift every day,
Improve assembly quality.
