    • A method for executing mechanical overload protection to prevent commanding a control signal to a linear actuator that may mechanically overload the linear actuator when an overload condition of the linear actuator is detected, the linear actuator utilized for controlling a movable element associated with the linear actuator responsive to the control signal, includes monitoring an overload condition based on position change of the movable element associated with the linear actuator during an integration period and excess energy during the integration period, de-energizing the linear actuator when an overload condition has been detected, monitoring an overload retry counter based on the number of cycles the overload condition is detected, comparing the overload retry counter to an overload retry threshold, an reenergizing the linear actuator when the overload retry counter is less than the overload retry threshold and maintaining de-energizing of the linear actuator when the overload retry counter is at least the overload retry threshold.
    • 一种用于执行机械过载保护的方法,以防止在检测到线性致动器的过载状况时对线性致动器进行机械过载的线性致动器的控制信号,用于控制与线性致动器相关联的可移动元件的线性致动器响应 对于控制信号,包括在积分期间基于与线性致动器相关联的可移动元件的位置变化以及在积分期间内的过剩能量来监视过载状态,当已经检测到过载状况时,使线性致动器断电 基于检测到过载条件的循环次数的过载重试计数器,将过载重试计数器与过载重试阈值进行比较,当过载重试计数器小于过载重试阈值并重新激活线性致动器时, 线性执行机构过载时 尝试计数器至少是过载重试阈值。

    • An endgate assembly connectable to a vehicle body for opening and closing a vehicle bed formed by the body includes an endgate supportable by the vehicle body at a pivot connection and openable and closable by pivoting about the pivot connection. A keyed support member is securable to the vehicle body. A damper and a cable are connected to the endgate. Both the damper and the cable have ends that are configured to be retained by the keyed support member when the endgate is pivoted between the open and closed position. The cable and damper ends can be removed from the keyed support member without tools when the cable end is rotated relative to the keyed support member. A method of modifying the vehicle bed by detaching or reattaching the endgate assembly is also provided.
    • 可连接到车体的用于打开和关闭由本体形成的车床的端盖组件包括可枢转连接处可由车身支撑的端盖,并且可通过围绕枢轴连接枢转而可打开和关闭。 钥匙支撑件可保证车身安全。 挡板和电缆连接到端盖。 阻尼器和电缆都具有当端盖在打开位置和闭合位置之间枢转时构造成由键控支撑构件保持的端部。 当电缆端相对于带键支撑构件旋转时,电缆和阻尼器端部可以从键盘支撑构件上移除,而无需工具。 还提供了一种通过拆卸或重新安装端盖组件来改变车床的方法。
