boom forklift, as is commonly used in construction, industrial, maintenance and repair applications.本发明波及一种普遍繁华型车辆，如一种伸缩臂叉，像人们一般用于建筑，工业，保养和维修中的应用。 More particularly, the present invention relates to a control system for such reach-type vehicle that is adapted for use in combination with a personnel work platform (PWP) that can be used in combination with the reach-type vehicle.更具体地说，本发明波及一种达到这种类型的车辆控制系统，联合使用了人事工作平台（工作），可以结合使用的覆盖面型车辆改装。 Presently, extendible boom forklifts can be used with a separate personnel work platform such that the forklift can be used to raise and lower workers standing on the platform based on various workplace requirements.目前，伸缩臂叉车可以使用一种单独的人事工作平台，使得叉车可用于提高和减少工人在不同的工作规定为基本的平台的地位。 The personnel work platform typically includes a pair of tubular fork receivers that receive the forks of the forklift such that the personnel work platform is supported on the forks of the forklift.人事工作平台，一般涉及一种管状交叉接受机接受的叉车叉，这样的人事工作平台上的支持对叉车叉。 Typically, an operator sits in the cab of the extendible boom forklift and raises and lowers the personnel work platform into the desired location.一般状况下，操作员坐在伸缩臂叉车的驾驶室和提高，并减少到所需的位置人员的工作平台。 Thus, the combination of the personnel work platform and the extendible boom forklift increase the number of functions the extendible boom forklift can perform at a workplace.因此，结合人事工作平台和伸缩臂叉的增长某些功能的伸缩臂交叉可以执行在工作场合。 Although the combination of the extendible boom forklift and the personnel work platform increase the utility of the extendible boom forklift, the workers supported by the personnel work platform can be injured if the control functions of the extendible boom forklift are not modified when the personnel work platform is being used.尽管伸缩臂交叉组合和人事工作平台增长伸缩臂交叉实用程序，由人事工作平台所支持的工人受伤如果伸缩臂叉车的控制功能时，不会修改人事工作平台正在使用。 For example, if workers are on the platform and the forklift is allowed to move or the fork assembly is allowed to rotate, or the forklift frame is not leveled correctly, the workers could become injured as a result of such movement.例如，如果工人在平台上，并容许叉车交叉装配移动或容许旋转，或不平整叉车框架对的，工人也许成为由于这种运动的成果受伤。 Therefore, it is an object of the present invention to provide a control system for an extendible boom forklift or similar boom-type vehicle that limits the operation of the vehicle when the personnel work platform is being used.因此，它是本发明提供了一种类似的伸缩臂叉或臂式车辆，限制车辆操作人员的工作平台时，正在使用的控制系统对象。 Further, it is an object of the present invention to provide relatively slow movement of the frame leveling cylinder when the personnel work platform is in use.此外，它是本发明的目的，以提供相对均衡的框架缓慢运动时，气缸工作平台的人员正在使用中。 A still further object of the invention is to provide a system for preventing movement of the vehicle and for providing controlled movement of the boom when the personnel work platform is in use.该项发明的目的是进一步为避免车辆移动，并提供运动控制的热潮时，工作人员使用的平台是一种系统。 Further, it is an object of the present invention to incorporate a shut-off switch on the personnel work platform such that the workers standing on the personnel work platform can shut down operation of the vehicle boom from the work platform.此外，它是本发明的对象纳入关闭对人事工作平台切换，使得工人对工作人员站在平台上可以关闭了从工作平台车热潮的运作。 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，另一种发明的目的是提供一种控制系统，工作筹划锁定稳定的叉车气缸和避免操作时，辅助液压叉车工作筹划中的运作模式。SUMMARY OF THE INVENTION本发明的概要 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).本发明是一种控制系统，修改，如伸缩臂叉，当车辆正在与一间人事工作平台（工作）连接使用了一种繁华型车辆，经营。 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.本发明的工作筹划控制系统修改了叉车作业，以增长对工人的安全工作平台定位。 The PWP control system includes a shut-off switch that is mounted near the work platform and a PWP system actuator switch.工作筹划控制系统涉及关闭开关，接近工作平台和工作系统的执行器开关上。 The shut-off switch and PWP system actuator switch are interconnected with a control microprocessor included in the electronic operating circuit for the forklift.在关闭开关及工作筹划系统互相连接器与开关控制微解决器中的电子工作电路涉及叉车。 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.微解决器控制操作配备为选择性的叉车工作筹划中的多种操作模式，这是比一般的操作模式不同的组件。 The PWP system actuator switch is positioned in the cab of the forklift and must be actuated for the PWP control system to enter the PWP mode.工作系统的执行器开关是定位在叉车驾驶室和必须为工作筹划控制系统进入工作筹划模式驱动。 In addition to the actuation of the PWP system actuator switch, the microprocessor must detect the simultaneous actuation of the service brakes.除了工作系统的开关驱动器，微解决器必须检测服务的刹车同步驱动。 Specifically, 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.具体来说，工作系统执行机构和服务刹车开关必须同步申请了五秒钟内容许前微解决器控制系统进入工作筹划模式。 Upon entering the PWP mode, the PWP control system performs several functions to further ensure the safety of a worker on the personnel work platform.在进入工作筹划模式下，工作筹划控制系统执行几种功能，以进一步保证对人事工作平台工人的安全。 Upon entering the PWP mode, the microprocessor sends a signal to the transmission controller, which causes the transmission of the forklift to declutch, to prevent movement of the forklift.在进入工作筹划模式下，微解决器发送到传播控制器，从而导致了叉车传播离合，以避免叉车的运动信号。 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，解决器激活停车制动和锁定后轴稳定的叉车系统提供一种安全的四点立场。 Once the forklift enters the PWP mode, the PWP control system checks to determine whether the cab of the forklift is in a generally level orientation.一旦进入叉车工作筹划模式下，工作筹划控制系统检查，以拟定与否叉车驾驶室在一般水平方向。 Specifically, a level sensor/switch in the cab provides a signal to the microprocessor indicating the orientation of the cab.具体来说，A级传感器/开关在驾驶室微解决器提供了一种批示方向的驾驶室信号。 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.如果传感器/开关决定了驾驶室倾斜的一种方式或其她超过2 ，微解决器将禁用繁华的叉车操作，以避免人员的工作平台运营。 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.除了控制各业务部门的叉车，微解决器导致在液压流体流向的模式后，进入叉车工作平缸限制。 The flow restriction reduces the rate at 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.流量限制减少的速度调平缸工作，以避免被扔在平台上的平台工人由于针尖对由不对的的平缸运动所导致的叉车。 The PWP control system of the invention includes the shut-off switch that is mounted to the personnel work platform.本发明的控制系统涉及工作筹划关闭互换机，安装在人事工作平台。 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.如果对人事工作平台的欲望工人，以避免任何进一步行动的热潮，劳动者可以克制关闭开关。 When the shut-off switch is moved to its OFF position, the microprocessor activates a joystick disengage solenoid that prevents any further movement of the boom.当关闭开关移动到OFF位置的，微解决器激活一种操纵杆脱离电磁铁来避免任何进一步的运动热潮。 Thus, a worker on the platform can prevent further movement of the platform by an operator in the forklift cab.因此，在平台上可以避免工人在叉车驾驶室操作平台的进一步行动。 Various other features, objects and advantages of the invention will be made apparent from the following description taken together with the
