Manual Hoist specifications of the hoist rope securely fixed

 With the provisions of models, specifications of the hoist rope securely fixed . Hand hoist wire rope , synthetic material is generally metal , so it must be done in full respect of maintenance , in order to not affect the normal use of the device . Usually comes with electric chain block a conical squirrel cage rotor brake motor (or reprovision cylindrical electromagnetic brake rotor motor ) drive , weight is generally from 0.1 to 80 tons , lifting height of 3 to 30 meters . In addition to electric hoist can be used alone , but also with manual or electric car chain assembled together , hanging in the roof of the building or crane beam.

Electric hoist is a remarkably versatile small light lifting equipment . No need to add oil to use in the monorail trolley operation , are not allowed to use other than to replace the rope with a supporting rope ; operation, the rope should be kept clean to prevent the adhesion of mud and oil into the machine , affecting the normal use or wear and tear plus clamp . Electric hoist, electric hoist short . Most electric hoist used by people on the ground following the manipulation button can also be manipulated or wired ( wireless ) remote control in the cab .

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
