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 lectric winch 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 programming lectric winch 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 View Details

Electrical instruments electric winch and speakers, lights electric winch are in working order, battery electrolyte fluid level check for compliance; relative density of the electrolyte is in compliance with requirements. check the forklift (forklift) or DC motor and engine lubrication conditions and control forklift lubrication lubrication points, add a little oil, gear oil and grease. check hand chain hoist  parts lines and fittings for damage, loose and leaking oil. Particularly brake hydraulic system and the master cylinder, wheel cylinders for leakage. check the tire pressure is in compliance with the magnetic lifter  requirements, vehicle tools and accessories are complete. New forklift during the initial period, the rough surface of the parts processing research not yet fully flat shape after machining and assembly location there are still some bias, with the gap and there will be a gap lubrication conditions, wear and tear to be bigger, relatively speaking working temperature slightly higher. check the mechanical couplings forklift tightening, especially steering system, wheels and tires, and other lifting mechanism and locking bolts are tightened to the correct device.                                     View Details

Measuring point from reflective surfaces and other objects should not be less than 1 m, is apart from the wall Angle should not be less than 2 m. Wire rope electric hoist braking slide was measured 3 > : under the rated frequency, rated voltage and rated load, the determination of the decline in steady decline of the braking distance, generally USES the fine steel wire rope hanging a thallium, using a fixed position, and can also use drum and shell the relative position of a point, take the average of 4 times in a row. 4 > record the voltage and current. 5 > step-down test: under the rated load, wire rope electric hoist on the test bench, according to the grading standard of step-down pressure indicators, namely the motor inlet before the test to the specified step-down goals to reduce voltage adjustment.                                     View Details
Forklift truck hydraulic electric winch system four big loss

When the engine and hydraulic pump joint work, from the engine speed characteristic and the universal characteristics, each engine speed control rod position corresponds to the best energy saving working point and the maximum power point, as the engine and hydraulic pump hydraulic pump absorption power and adjustment the best match. Due to the variability forklift workload, the absorption of the hydraulic pump power change, causes the engine speed deviating from the optimal node. 3, energy transmission loss in the hydraulic system Forklift truck hydraulic system pipeline is usually composed of several section of pipeline in series, each series, and some, such as elbow, control valves, filters, pipe connection device such as a form of local resistance, when the hydraulic oil flow through the pipe, elbow, control valve and pipe joint produced when along and the pressure loss and local pressure loss; Executive components such as hydraulic cylinder work due to the unreasonable design and processing technology, the friction contact area vice friction losses. The pressure and friction loss of oil flow resistance and heat change, causes the hydraulic system oil temperature is too high. According to related statistics, when forklift truck hydraulic system oil temperature over 85 degrees Celsius, large expansion coefficient of aluminium shell to produce secondary class phenomenon, hydraulic valve is easy to be jammed, lifting oil cylinder rising velocity decreased obviously, sealers and high pressure hose is easy to aging, components of holes and cracks are easy to jam. 4, energy loss Forklift at work while driving is on homework, frequent load change and the change range is larger. When the hydraulic system working there are three times of energy conversion, including high pressure oil pump, can converts mechanical energy to the pressure; Execute device and hydraulic components to the oil pressure can be converted into mechanical energy and heat. The whole process of energy conversion and transmission with energy loss, at the same time, engine, pump, valve, load don't match each other also can produce larger energy loss.                                     View Details
