hoist equipment mast distortion correction method can be eliminated

Electric forklift mast distortion correction method can be eliminated. When bending and twisting deformation is small, allowing the cold calibration correction method applied motorized chain hoist static load . When bending , distortion is too large, correction is difficult to use cold , heated correction should be heated to minimize the heating zone , the heating temperature is generally not more than 700 ℃, and slowly cooled so as to increase brittleness.three phase electric hoist mast crack repair : If the inspection found cracks should be repaired .repairs should be carried out before the forklift mast correction , maintaining the inherent straightness mast .grinding cracks to expose the metallic luster , and then carefully examined to determine the boundaries of the crack extends 10mm at the boundaries of the drill ¢ 5 - ¢ 8mm of limiting, holes.

Manual Hoist it selected for intensive applications

With a range of quite different , it selected for intensive applications , the various parts of the program  that is very closely coupled , such as word processing software, interactive graphics system . The VB and  Delphi (c + + builder and Delphi as Inprise company with products that use different languages ??in  addition to the remaining features almost identical ) code is very suitable for those large , multi-  interface , high degree of independence module , low coupling management system, especially with a large  database on the processing application . VB and Delphi are RAD (RapidApplicationDevelopment, rapid  application development ) development tool , which can greatly improve monorail trolley programming efficiency , but their  underlying code execution efficiency and flexibility , but not as good as some of the VC. According to the  characteristics of the test system , I chose to develop Windows2000 VisualC + +6.0 based monitoring and  control procedures. 4.3 Monitoring 4.3.1 test software development process control IPC is responsible for  the system test process control and management, but also to achieve a self-test function cargo belts of the system ,  and therefore , the test flow control sub-module is the key to the entire test module module , specific  processes such as Figure 4-1. The following brief description of what the testing process in several key  questions: ( 1 ) Although the test system has a self-test module , but in the entire testing process, the  test system is constantly monitoring the current state of each underlying device , if there are problems ,  issues the nature of the quick decisions and take appropriate measures to deal with . Such as laser  distance sensor error , the test software will automatically restart the device and prompts the operator

indicate Manual Hoist unauthorized logo may not be used

The tool should be accompanied by a written explanation detailing the precautions to be taken , and indicate unauthorized logo may not be used. The tool should be handed over to authorized personnel .
Door Protection 5.8.5 workbench
Electrical safety switch should be set when the door is not completely closed, lifting platform should stop or not start.
5.8.6 Emergency Operation
It should be at the bottom with a power failure or malfunction in the emergency operating device platform so the Manual Hoist decline , and there are clearly marked ; the device should continue to rely on force control. Such as when using the control handle , the handle of the operation should be consistent with the direction of the direction of motion control functionality , release the control handle when should automatically return to the " stop" or intermediate position.
5.8.7 Anti- personnel cut protection
Greater than or equal to 3 floors in layers lifting platform, when the horizontal distance between the table and the floor wellhead less than 0.5m, the table should be set at the bottom of the surrounding anti-collision device, when the decline encounter obstacles should stop the lifting platform .
