The minimum steady speed wheeled crane commissioning

This is the minimum steady speed of wheeled cranes debug introduced into working conditions, methods and requirements of three parts
1. Debug condition
Base pipe frame, engine rated speed, rated amplitude maximum rated lifting weight lifting
2. Debugging method
 Manipulation engine throttle control Hand fixed lift table speed and other institutions * are the lifting, down, left and right turning movements reach a steady speed as low as possible. Determination of uniform through - determine the distance required time period, lifting movement distance of not less than 1m, rotary motion angle of not less than 180. , Were calculated from the rise, fall, swing the minimum steady speed, and with the requirements of crane design data comparison.
3. Straddle stackers for commissioning
(A) single rope hoist rated speed, rated rotation speed, no load rotation speed is not less than the design value.
(2> The maximum rated lifting capacity crane operations, lifting, and turning down the minimum steady speed shall not exceed the total community

Comfortable control of the rate of decline

Product description:

If you are using and managers to fully understand the whole structure, principles, technical performance, design specified conditions of use, security technology, you will get the best results.

  Crane various properties in the actual production can be fully played, depending on the actual use are reasonable. If resorted to improper maintenance, heavy machinery wheeled Zhao difficult to be effective, will exacerbate the wear and cranes sail affecting life, and even cause accidents. If you are using and managers to fully understand the whole structure, principles, technical performance, design specified conditions of use, security technology, you will get the best results. This section focuses on the use of mobile cranes described in security technology.
  (A) the operator
     Crane operators   electric lifts  be subject to strict Luo theoretical training expertise and practical technical training, proficiency in vehicle driving and crane operators two technologies. Not only to master the crane structure, working principle and technical performance, and should be read in various cooked Random technical documents, such as brochures, manuals performance, operation and maintenance manuals and safe use of rules, but also memorize the various provisions in the operation signals master - · some basic knowledge and skills.
     (Two) safe working   electric lift table  conditions
     Cranes at work due to bad weather, such as high winds, thunderstorms, big men, etc., should stop work; prohibited in a landslide hazard venue working near transmission lines; at night or in the operator's view is obstructed operating conditions, there must be reliable measures, and must be directed with the job; complex field operations in terms of personnel, generally set Starsky signs and safety fence, or someone on duty as a security guard

Wheeled crane repairs

This article explains wheeled crane repair work , from understanding the phenomenon , determine the cause talk , to determine a repair solution has been
( A ) failure to understand the phenomenon
 Crane parts during operation partner suddenly suddenly invaded or mountain now crawling , vibration, abnormal temperature rise and smoke , smell, sound, meter pointer jump swing , oil spills, leaks , leaking , leakage , control failure , etc., called Zhao fan malfunction.
 When the crane when a fault occurs , some phenomena can clearly be observed , and some Hand fixed lift table imperceptible . Maintenance and inspection must be carefully observed in order to find the real source of it down .
 ( Two ) analyze the cause
Yi Gu array of phenomena as the basis, in accordance with the rules and guns corporate failure by practical experience, control apricot find relevant information , Shop Lifter of similar phenomena whose failure may occur for various reasons , sub- Xin structure and [ : operating principles , discussed to determine the real cause of the malfunction .
 ( Three ) to determine demolition site
Failure Analysis is based to determine what caused the failure of the parts, and the parts of the system to determine the demolition inspection of the site.
( Four ) demolition inspection
For determining the dismantling of the site, shall give rise to the possibility of failure , to determine the sequence of disassembly
Unloading operations, except in compliance with - ' suits mechanical disassembly required outside, but also pay attention to the following questions:
 1 . Preparation for traveling to run dry stable frame bracket pad Zhao , prohibited the use of leg support frame.
 2 . Standby system at ten non-working state
 Yi closed engine , release the hydraulic system and pneumatic system 44 residual Osteoform . In order to avoid injury.
