U-Shaped Twin-Pin Lifting Yoke Assembly

"A highly detailed 3D CAD assembly render, isometric view on a studio white background, showcasing a heavy-duty U-shaped hook arm assembly (Cụm Cánh tay móc) from SolidWorks, designed for lifting 50kg water dispensers. Structure & Materials: A massive overhead cross-member plate (tấm bích liên kết trên) made of 10mm thick galvanized steel, featuring a bolt-hole pattern, gussets, and ribs, mounted beneath a guided Z-axis carriage. Two vertical drop-down arms (cánh tay dọc) forming a rigid U-shaped yoke, fabricated from 8mm thick CNC-cut steel brackets, reinforced with triangular stiffeners and weldment lines. Vertical length is around 600mm, drop-down parallel on both sides. Horizontal Actuation & Guided Sliding: Mounted on the outer lower section of each arm is a compact horizontal pneumatic cylinder (SMC style, aluminum body with steel tie rods and miniature elbow air fittings connected to blue/black pneumatic hoses). A linear guide mechanism (miniature rail and carriage or dual guide rods) is integrated to ensure precise horizontal inward/outward sliding (30mm stroke) of the grabber. Hook & Pin mechanism (Ngón móc): On the inner side, the piston connects to a sliding gripper carriage holding the heavy-duty lifting hook/pin (ngón móc). The hook features an inner steel core (C45) for shear strength, encased in a bulky, molded white/off-white POM (polyoxymethylene) non-abrasive plastic sleeve with chamfered edges to insert into a 3D recessed handle on a water dispenser. Engineering details: Visible fasteners (M6/M8 socket head cap screws, hex nuts, washers), bracket alignment slots, sensor mounting brackets (small proximity sensors on the side), and air line routing. Shaded-with-edges CAD style, showcasing realistic industrial materials: matte-finished dark grey steel, brushed aluminum cylinders, brass/steel fittings, and matte white/grey POM plastic. Annotated with ghosted reference outlines of the target water dispenser's side panels and recessed pockets on both sides to demonstrate the grip. Fully assembled with highly precise industrial mates, 3D orthographic and mechanical interface highlights."
