摘要： A heating device for heating a substantially planar screed plate for a paving machine comprising a plate being spaced from the screed plate, and a space being defined therebetween. A heated gas inlet feeds into a tunnel connecting to the space. At least some of the heated gas is directed from the tunnel substantially parallel to the screed plate. The tunnel is formed from a plurality of tunnel branches with a orifice attached to the end of each tunnel orifice determining the direction where the heated gas will be directed.

摘要： In the embodiment shown, the assembly comprises a pair of apertured weights mounted on a rotatable shaft, each of the weights having abutment surfaces one or another pairs of which close upon each other, depending upon the direction of shaft rotation. One of the weights is keyed to the shaft to rotate therewith; the other weight is freely rotatable relative to the shaft. Upon rotation of the shaft in a first direction, a first pair of the abutment surfaces engage, and the eccentricities of the weights then are so disposed as to produce a given-amplitude vibratory force. Upon rotation of the shaft in a contrary direction, a second pair of the abutment surfaces engage, and the eccentricities of the weights then are so disposed as to produce a vibratory force of a differing amplitude.

摘要： A mobile crane includes a chassis having first connection features located on a rear end thereof. An outrigger includes second connection features for mating with the first connection features. A tag axle assembly includes third connection features for mating with the first connection features. The first connection features may accept either the second connection features or the third connection features, so that the mobile crane may be selectively configured for highway travel and selectively configured for working operation. One or more axles of the mobile crane may be elevated when the tag axle assembly is connected to the first connection feature. Further, a wheeled boom dolly may be employed to share weight with the chassis when the mobile crane is travelling. By allowing the outrigger to be replaced with the tag axle assembly, the present invention allows the mobile crane to be conveniently configured for road travel in a manner suitable to the axle spacing and axle weight restrictions of the local area.
摘要翻译：移动式起重机包括具有位于其后端上的第一连接特征的底盘。外伸支架包括用于与第一连接特征配合的第二连接特征。标签轴组件包括用于与第一连接特征配合的第三连接特征。第一连接特征可以接受第二连接特征或第三连接特征，使得移动式起重机可以被选择性地构造成用于高速公路行驶并且被选择性地配置用于工作操作。当标签轴组件连接到第一连接特征时，移动式起重机的一个或多个轴可以升高。此外，当移动式起重机行驶时，可以使用轮式起重臂台车来与底盘分配重量。通过允许使用标签轴组件替换外伸支架，本发明允许移动式起重机以适合于局部区域的轴间距和车轴重量限制的方式方便地构造成用于道路行驶。
