Painting hanger

Painting hangers are jigs used on industrial painting lines to suspend workpieces, convey them, paint them, and dry them. A common setup combines a frame that hangs from the conveyor with level bars, the horizontal bars that hold the workpieces. Level bars come in several types: ready-to-use types with hooks, socket types that accept replaceable insert parts, and beam types with exchangeable hooks. Changing the number of tiers and the hook style allows use from high-density hanging of small parts to low-count hanging of large workpieces. In electrostatic and powder coating, the hanger grounds the workpiece, so electrical contact at the connection points is also part of the function.

How to choose Painting hanger

  1. 1. Select a frame that fits line dimensions

    Check that the frame width, height, and length fit the conveyor pitch and the opening dimensions of the booth and drying oven. The listed product has a width of 830mm, a height of 1000mm, and a length of 1050mm. Also check that the overall outline with workpieces hung does not interfere with equipment.

  2. 2. Workpiece size and level bar length

    The level bar length determines the range over which workpieces can be arranged horizontally. The listed product has a length of 800mm. Estimate how many workpieces one bar can hold from the sum of the workpiece width and the spacing needed for paint to reach all surfaces.

  3. 3. Assess output by suspension point count

    The more suspension points per hanger, the more parts can be painted at one time. The listed products include an example with 16 points. For small parts, choose models with more suspension points; for large workpieces, choose models with fewer points. Also check whether output can be adjusted by changing the number of tiers.

  4. 4. Check the maximum hook wire diameter

    Types with exchangeable hooks, such as beam types, have a maximum wire diameter for the hooks that can be installed. For example, some products are specified for wire diameters of 4mm or less. Confirm that hooks of a suitable thickness to bear the workpiece weight can be used.

  5. 5. Judge strength and load capacity from wire diameter

    The wire diameter of the frame and level bars affects stiffness and load capacity. The listed frame uses 8mm wire, and the level bars range from 1 to 8mm. Heavy workpieces are prone to deflection or dropping, so select a product with sufficient wire diameter margin.

  6. 6. Hook style, electrical contact, and maintainability

    Hook styles that keep workpieces from slipping off prevent drops during conveying. For electrostatic painting, confirm the structure maintains electrical contact. Hooks with paint buildup require replacement or stripping, so a structure that allows hooks and insert parts to be replaced makes maintenance easier.
