15、 the work platform.此外，它是本發(fā)明的對象納入關(guān)閉對人事工作平臺(tái)切換，使得工人對工作人員站在平臺(tái)上可以關(guān)閉了從工作平臺(tái)車熱潮的運(yùn)作。 Yet another object of the invention is to provide a PWP control system that locks the stabilizing cylinder of the forklift and prevents operation of auxiliary hydraulics when the forklift is in a PWP mode of operation.然而，另一種

16、發(fā)明的目的是提供一種控制系統(tǒng)，工作籌劃鎖定穩(wěn)定的叉車氣缸和避免操作時(shí)，輔助液壓叉車工作籌劃中的運(yùn)作模式。 SUMMARY OF THE INVENTION本發(fā)明的概要 The present invention is a control system that modifies the operation of a boom-type vehicle, such as an extendible boom forklift, when the vehicle is being used in connection with a personnel work platform (PWP).

17、本發(fā)明是一種控制系統(tǒng)，修改，如伸縮臂叉，當(dāng)車輛正在與一間人事工作平臺(tái)（工作）連接使用了一種繁華型車輛，經(jīng)營。 The PWP control system of the present invention modifies the operation of the forklift to increase the safety of workers positioned on the work platform.本發(fā)明的工作籌劃控制系統(tǒng)修改了叉車作業(yè)，以增長對工人的安全工作平臺(tái)定位。 The PWP control system includes a shut-off switch tha

18、t is mounted near the work platform and a PWP system actuator switch.工作籌劃控制系統(tǒng)涉及關(guān)閉開關(guān)，接近工作平臺(tái)和工作系統(tǒng)的執(zhí)行器開關(guān)上。 The shut-off switch and PWP system actuator switch are interconnected with a control microprocessor included in the electronic operating circuit for the forklift.在關(guān)閉開關(guān)及工作籌劃系統(tǒng)互相連接器與開關(guān)控制微解決器中的電子工作電路

19、涉及叉車。 The control microprocessor is configured to selectively operate various operating components of the forklift in a PWP mode, which is different than the normal mode of operation.微解決器控制操作配備為選擇性的叉車工作籌劃中的多種操作模式，這是比一般的操作模式不同的組件。 The PWP system actuator switch is positioned in the cab of the forkl

20、ift and must be actuated for the PWP control system to enter the PWP mode.工作系統(tǒng)的執(zhí)行器開關(guān)是定位在叉車駕駛室和必須為工作籌劃控制系統(tǒng)進(jìn)入工作籌劃模式驅(qū)動(dòng)。 In addition to the actuation of the PWP system actuator switch, the microprocessor must detect the simultaneous actuation of the service brakes.除了工作系統(tǒng)的開關(guān)驅(qū)動(dòng)器，微解決器必須檢測服務(wù)的剎??車同步驅(qū)動(dòng)。 Speci

21、fically, the PWP system actuator switch and the service brakes must be simultaneously applied for a period of five seconds before the microprocessor allows the control system to enter the PWP mode.具體來說，工作系統(tǒng)執(zhí)行機(jī)構(gòu)和服務(wù)剎車開關(guān)必須同步申請了五秒鐘內(nèi)容許前微解決器控制系統(tǒng)進(jìn)入工作籌劃模式。 Upon entering the PWP mode, the PWP control syste

22、m performs several functions to further ensure the safety of a worker on the personnel work platform.在進(jìn)入工作籌劃模式下，工作籌劃控制系統(tǒng)執(zhí)行幾種功能，以進(jìn)一步保證對人事工作平臺(tái)工人的安全。 Upon entering the PWP mode, the microprocessor sends a signal to the transmission controller, which causes the transmission of the forklift to declutch,

23、to prevent movement of the forklift.在進(jìn)入工作籌劃模式下，微解決器發(fā)送到傳播控制器，從而導(dǎo)致了叉車傳播離合，以避免叉車的運(yùn)動(dòng)信號。 At the same time, the processor activates the parking brake and locks the rear axle stabilizing system of the forklift to provide a secure four-point stance.同步，解決器激活停車制動(dòng)和鎖定后軸穩(wěn)定的叉車系統(tǒng)提供一種安全的四點(diǎn)立場。 Once the forklift en

24、ters the PWP mode, the PWP control system checks to determine whether the cab of the forklift is in a generally level orientation.一旦進(jìn)入叉車工作籌劃模式下，工作籌劃控制系統(tǒng)檢查，以擬定與否叉車駕駛室在一般水平方向。 Specifically, a level sensor/switch in the cab provides a signal to the microprocessor indicating the orientation of the cab.具

25、體來說，A級傳感器/開關(guān)在駕駛室微解決器提供了一種批示方向的駕駛室信號。 If the sensor/switch determines that the cab is tilted one way or the other more than 2°, the microprocessor will disable operation of the forklift boom to prevent movement of the personnel work platform.如果傳感器/開關(guān)決定了駕駛室傾斜的一種方式或其她超過2 °，微解決器將禁用繁華的叉車操作，以避免人員的工作平臺(tái)運(yùn)營。

26、 In addition to controlling various operational components of the forklift, the microprocessor causes a restriction in the flow of hydraulic fluid to the leveling cylinder of the forklift upon entering the PWP mode.除了控制各業(yè)務(wù)部門的叉車，微解決器導(dǎo)致在液壓流體流向的模式后，進(jìn)入叉車工作平缸限制。 The flow restriction reduces the rate at

27、which the leveling cylinder operates to prevent a worker on the platform from being thrown from the platform due to a tip-over of the forklift caused by incorrect movement of the leveling cylinder.流量限制減少的速度調(diào)平缸工作，以避免被扔在平臺(tái)上的平臺(tái)工人由于針尖對由不對的的平缸運(yùn)動(dòng)所導(dǎo)致的叉車。 The PWP control system of the invention includes t

28、he shut-off switch that is mounted to the personnel work platform.本發(fā)明的控制系統(tǒng)涉及工作籌劃關(guān)閉互換機(jī)，安裝在人事工作平臺(tái)。 If a worker on the personnel work platform desires to prevent any further movement of the boom, the worker can depress the shut-off switch.如果對人事工作平臺(tái)的欲望工人，以避免任何進(jìn)一步行動(dòng)的熱潮，勞動(dòng)者可以克制關(guān)閉開關(guān)。 When the shut-off swit

29、ch is moved to its OFF position, the microprocessor activates a joystick disengage solenoid that prevents any further movement of the boom.當(dāng)關(guān)閉開關(guān)移動(dòng)到OFF位置的，微解決器激活一種操縱桿脫離電磁鐵來避免任何進(jìn)一步的運(yùn)動(dòng)熱潮。 Thus, a worker on the platform can prevent further movement of the platform by an operator in the forklift cab.因此，在

30、平臺(tái)上可以避免工人在叉車駕駛室操作平臺(tái)的進(jìn)一步行動(dòng)。 Various other features, objects and advantages of the invention will be made apparent from the following description taken together with the drawings.其她多種功能，對象和發(fā)明將作出明顯的優(yōu)勢，采用了從圖紙一并提供如下闡明。 BRIEF DESCRIPTION OF THE DRAWINGS簡要闡明圖紙 The drawings illustrate the best mode pr
