Abstract: Provided is a lightweight aluminum alloy carriage, which relates to the field of lightweight logistics equipment manufacturing application. The lightweight aluminum alloy carriage comprises a bottom plate assembly, and the bottom plate assembly comprises a front end part and a rear end part which are arranged front and back on an axis; the front end part comprises a transversely arranged aluminum alloy profile bottom plate, and the extrusion direction of the transversely arranged aluminum alloy profile bottom plate is perpendicular to the axis of the bottom plate assembly; and the rear end part comprises aluminum alloy square tube cross beams and a longitudinally arranged aluminum alloy profile bottom plate, and the aluminum alloy square tube cross beams are perpendicular to the axis of the bottom plate assembly.

Abstract: The present invention provides a braiding machine and a braiding method of a seamless wound braided rope. The braiding machine of the seamless wound braided rope has simple structure, good stability and high yield; and colors of an inner core and an outer skin of the braided rope braided by the braiding machine are different, as an early-warning effect.

Abstract: The present invention provides a braiding machine and a braiding method of a seamless wound yarn rope. The braiding machine of the seamless wound yarn rope comprises a machine frame, a gallop knitting tray, a plurality of gallop knitting ingots and a rope belt braiding mechanism. The braiding machine of the seamless wound yarn rope has simple structure, good stability and high yield.

Abstract: The present invention provides a using method of a seamless rope ring, comprising the following steps: sawing a braided end of the seamless rope ring and a tail end of the seamless rope ring together to form a double-lap seamless rope ring with a halved length; alternately winding a hitch-pulling rope and the double-lap seamless rope ring; and braiding a braided end of the hitch-pulling rope and a tail end of the hitch-pulling rope together to form a ring hitch. The seamless rope ring has a simple using method and extendable length so that the seamless rope ring has multiple purposes and using strength of the seamless rope ring is greatly enhanced.

Abstract: The present invention discloses a woven mesh and a safety waist protection belt. The woven mesh comprises a plurality of parallel safety ropes and mesh sleeves which are integrally woven and sleeved on the periphery of the safety ropes. A plurality of tight joint segments are sequentially arranged between adjacent safety ropes at intervals in a length direction. The adjacent mesh sleeves at the tight joint segments are integrally woven. The present invention also provides a safety waist protection belt which comprises the above woven mesh, a face fabric layer, a lining layer, covered edges arranged at an edge of the face fabric layer and an edge of the lining layer respectively and hollow woven belts extending from two ends of the safety waist protection belt respectively. The safety waist protection belt designed with the structure is light in weight, high in tensile strength and comfortable to wear.

Abstract: The present invention discloses a quickdraw device including quickdraw buckles and a woven tape for connecting the adjacent quickdraw buckles. The woven tape is arranged in a hollow cylinder shape. Ports are penetrated on both ends of the woven tape. At least one port of the woven tape is arranged to be curled along a length direction of the woven tape. An inner diameter of the woven tape is equal to an inner diameter of the port. In such design, tensile strength of the woven tape can be effectively enhanced through the curled woven tape. Without sewing, processing is more convenient and quick.
