Choose the leaf arrangement around the usable passage your operation needs. A wider wall opening does not by itself determine how much clear space will remain with the proposed frame, hardware and leaves.
| Arrangement | Questions to resolve |
|---|---|
| Single leaf | Will the loaded cart and operator fit through the proposed clear passage? Is there room for the leaf on both approaches? |
| Double leaf | What clear passage is available with the proposed leaves open? How will approaching traffic be managed? |
| Unequal double leaf | Would a different leaf split suit routine passage and occasional larger equipment? What hardware and opening procedure are needed? |
These arrangements are listed in the SHUANGLUAN METAL catalog, pages 4 and 7. Selection depends on the project; confirm usable passage and swing space on the drawing for your opening.
Check the complete route
Provide the maximum loaded cart width, height and length, including protruding handles or goods. Show turns near the doorway, wall returns, nearby equipment and the floor condition. Record the traffic direction and whether people and carts regularly approach from both sides.
Ask the supplier to identify the resulting clear passage and leaf movement on the proposed drawing. Check the bumper contact height against the equipment. A second leaf does not establish suitability for forklifts or powered impact.
Buyer questions
Is double leaf always better?
Suitability depends on usable passage, approach space, operation and installation conditions. Compare drawings for the actual opening.
Can I choose unequal leaves?
The catalog lists this arrangement. Confirm the leaf split, hardware and operation for your project.
Can a photograph establish the maximum cart size?
Use measured site and equipment dimensions and the proposed drawing. Perspective in an image cannot establish clearance.
What should an installer confirm before ordering?
Confirm the measurement reference, finished floor, supporting wall or frame, hardware and fixing details, supply scope and approved drawing.
