摘要： A shoe (10) for a crawler track has two roller paths (16, 17) thereon, upon which a dual rim roller travels in use. The roller paths (16, 17) are aligned with leading and trailing lugs (11, 12) respectively, of the shoe 10. Drive lugs (18, 19) are provided on the outside of the roller paths (16, 17). In use, the drive lugs (18, 19) are engaged by sprocket teeth to drive the crawler track. The drive lugs (18, 19) stand proud of the roller paths (16, 17), but may also be recessed below the roller paths.

摘要： The invention relates to a method and device for producing a chain composed of chain links (2) and of connecting elements (1). According to the invention, the chain can be produced in an essentially continuous manner whereby largely eliminating the need to make separating cuts and enabling the production of loadable and durable articulated connections of chain links. To this end, the invention provides that: connecting elements each having two holes (1,1) are used; the connecting elements are inserted in cavities (3-5) in first tools, and; chain links (2) are produced with contact at least to partial areas of connecting elements. Inside the holes (1-1), joint pins (2-1) are produced that are a part of the chain links. The invention also relates to a method and device for producing a chain, which is composed of chain links and of connecting elements, made of shapeable materials, particularly plastic.

摘要： A clip on welder includes two pairs of opposed grippers defined by pivotally attached upper and lower frames for latching the welder to heat weldable material, such as a length of tubing, upon actuation of a start button by an operator; thereafter, the welder operates unattended. At least a jaw of a pair of jaws disposed intermediate the two pairs of grippers heats the material compressed and lodged therebetween to form a weld in or across the material. A source of gas, such as air, under pressure selectively connected to a bellows provides the power to pivot the upper and lower frames into gripping engagement with the material. A source of electrical signals provides the power to heat the material intermediate the pair of jaws. One or more thermocouples senses the heat of the jaws and generates signals used to control the application of power and to control cooling. After completion of the weld, cooling air is directed to the jaws until the thermocouple(s) signal(s) indicates a sufficiently low temperature. Release of the welder from the material is in response to actuation of a stop button by the operator.

摘要： A chain link belt includes a plurality of tube pairs, each pair comprising two tubes joined along their sides in a substantially parallel relation. A plurality of wires of predetermined lengths are used to join the tubes to form the belt links. The wires are formed in a quadrilateral with the tubes on opposite sides thereof and with the joined ends of the wire links positioned within one of the tubes hidden from view. One of the wires is engaged through one tube of the adjacent tube pairs and another wire is engaged through the other tube pairs for connection of other tube pairs to form the chain link belt.

摘要： In the manufacture of a cable-type tire chain having elongate flexible side members and cross-members carrying traction sleeves, the cross-members are connected to the side members by hooks which are crimped to the side members in a press. To assemble the cross members and side members, they are supported in an assembly jig, with the hooks attached to the opposite ends of the cross-members and embracing the side members. The hooks on one side of the chain are crimped simultaneously to the relevant side member in a single pressing operation while supported in the jig, which applies tension to the side member.

摘要： A chain welding machine has a first cam-operated linkage for rapidly movingpsetting dies into and away from the ends of a link to be welded and a second hydromechanical linkage for applying upsetting force to the ends of the link. The upsetting force is controlled by hydraulic pressure which is regulated as a function of time by a cam-controlled pressure-limiting valve.

摘要： A device for positioning the individual links of a length of chain having nks to be welded is disclosed. The device is used in connection with a chain welding machine wherein a length of chain is advanced step-by-step upwardly over a vertex defined by a saddle at which a welding station is located and then downwardly. The saddle is advantageously formed of a generally cylindrical, horizontally extending bolt affixed to the machine and which has a flattened top portion to which each chain link to be welded is advanced then erected for welding. Alternate links arrive at the flattened top of the bolt with the planes of successive links arranged at inclinations of 45.degree. to either side of a vertical plane containing the axis of the length of chain under the influence of the shape of the saddle and gravity.
