Jib crane boom margins mainly use (pitching) rotation around the vertical axis with lifting goods, the use of flexible action to meet the loading requirements, in the form of fixed, mobile and floating. Fixed jib crane mounted directly on the dock or pier base library field, can only work in situ. Some of the boom is not only pitching rotation, and some can tilt can be reversed.

Introduction crane dismantling acceptance testing system and file management system
About lifting machinery, you know it's removable system acceptance testing you? You know it's removable file management system specifically what you? Here's to answer questions about specific aspects of the overhead bridge crane dismantling these two questions, answers below.
1 Lifting disassembly inspection system detects what?
A: Lifting disassembly testing and acceptance testing and inspection system includes two parts, specifically are:
(1) Detection
a. detection environment must meet the specified requirements.
b. lifting machinery installed, must comply with the "crane installation procedures" the requirements, testing and acceptance of the basis for the "lifting machinery safety inspection outline."
c. disassembly of large construction machinery, its first detailed examination to check compliance with safety regulations, which do not meet the requirements, it can not be demolished.
d. inspection of lifting machinery to be used when instruments, measuring tools, or tools, etc., must have a certificate and to have someone to custody, to be measured periodically check to ensure precision and accuracy to prevent errors.
e. inspection work can not just assigned, it must be held by a provincial inspector certified personnel to operate, "self-test report card" must have inspectors Zhang Fang to be qualified.
(2) Acceptance
For large construction machinery, inspection personnel reference standard is "Construction Machinery Technology test procedures", the device must be remitted with the company Quality Division Abe, overhead gantry crane construction projects tripartite security personnel inspection and acceptance, not individually. The installation must be ready before the acceptance of documents, including basic construction materials, vertical horizontal measurement records, the installation program, safety technical tests, etc., but also fill in installation and acceptance record sheet.
(2) Lifting disassembly file management system, including what?
A: Lifting disassembly file management system include the following, in order:
(A) large construction machinery certificate, instruction manual, a variety of mechanical and electrical drawings, maintenance records, inspection records and other documentation testing must be classified, compilation of, custody and archiving.
(2) disassembly information should be completed, and to be truthful, not fraud, for the disassembly process produces a variety of technical construction data should be unified by the base machine management staff accommodating custody, can not be thrown away, but not easily destroyed.
(3) machine management staff mainly for large-scale machinery and equipment disassembly information management, hoist gantry crane in the management process, should do the following, in order:
a. variety of removable data should be timely collect, organize, archive storage, can not have missed, not mutual confusion.
b. If the information you want to borrow, copy, etc., should develop appropriate systems to ensure data integrity, not to be lost, and inform the loan officer or loan unit, there can be altered on the file information, swap and other damage behavior.
