摘要： A fluid power load-clamping system includes at least one fluid valve for variably regulating the maximum fluid pressure causing closure of the clamp. Preferably the valve increases the maximum fluid pressure automatically in relation to the measured magnitude of the weight of the load to regulate the load-gripping force. A controller causes the valve to permit a relatively high maximum fluid pressure as the clamp closes toward the load to enable high initial clamp closure speed. Thereafter the valve automatically reduces the maximum pressure as the clamping surfaces close into a predetermined relationship with the load, and then increases the maximum pressure to regulate the gripping force. Other preferable features include continuous weight-responsive automatic regulation of the gripping pressure while the load is supported by the clamp, and compensation of the weight measurement for the longitudinally-extensible position of the lifting mechanism, to maximize the accuracy of the load-weight measurement. Gripping pressure regulation is operable in response to linear load-lifting or tilting load-lifting, without concurrent clamp closure actuation. Different predetermined relationships between the weight of the load and the maximum gripping pressure are selectable alternatively. A gravity-referenced tilt controller adjusts the load automatically to an attitude which is untilted with respect to gravity. Lowering of the lifting mechanism is automatically prevented in response to the setting down of the load.
摘要翻译：流体动力负载夹紧系统包括至少一个流体阀，用于可变地调节最大流体压力，导致夹子闭合。优选地，阀门相对于测量的负载重量的大小自动地增加最大流体压力以调节负载夹紧力。当夹具朝向负载闭合时，控制器使得阀允许相对高的最大流体压力，以实现高初始夹紧闭合速度。此后，当夹紧表面与负载接合预定关系时，阀自动降低最大压力，然后增大最大压力以调节夹紧力。其他优选的特征包括连续重量响应的自动调节夹紧压力，同时负载由夹具支撑，以及对提升机构的纵向可伸展位置的重量测量的补偿，以最大化负载重量测量的精度。夹紧压力调节可以响应于线性负载提升或倾斜负载提升而操作，而不需要同时进行夹紧闭合驱动。交替地选择负载重量与最大夹持压力之间的不同预定关系。重力参考的倾斜控制器自动将负载调节到相对于重力直到的姿态。响应于负载的下降，自动防止提升机构的下降。

Other preferable features include an automatic limit on the rate of lift of the load during weighing, and compensation of the weight measurement for the longitudinally-extensible position of the lifting mechanism, to maximize the accuracy of the load-weight measurement. Automatic gripping pressure regulation is selectively operable in response to actuation of the lifting mechanism, which can be either a linear lifting mechanism or a tilting lifting mechanism, or both. Different predetermined relationships between the weight of the load and the maximum gripping pressure are selectable alternatively. A gravity-referenced tilt controller adjusts the load automatically to an attitude which is untilted with respect to gravity.

摘要： Improved bolted joint designs are used for a joint between a bolt-on load-lifting member such as a fork or clamp arm and a carriage or carrier associated with a material handling device. In various embodiments, an elongate rear vertical shank of one or the other of the load-lifting member or the carrier may have a plurality of mounting bolt holes spaced longitudinally along its length, each mounting bolt hole extending from a respective recessed area formed in one or both of the joined surfaces. Each bolt hole has a respective bolt-hole width dimension transverse to the elongate member, and each recessed area has a recess width dimension parallel to and greater than the bolt-hole width dimension.
