Redesign & Detailed Engineering of 90° Spiral Baggage Chute for Airport Baggage Handling System Ended
About the job
We are looking for an experienced mechanical design engineer / conveyor and material-handling equipment designer to redesign an existing 90° spiral chute used in an airport baggage handling system (BHS).
The existing chute is experiencing baggage jamming, particularly with cling-film/stretch-wrapped bags and cartons. Hard-shell suitcases and cloth/fabric bags generally slide satisfactorily.
We need a professional engineer to review our existing design, identify the root causes of the jamming, and develop an improved, manufacturable 90° spiral chute design that can reliably handle mixed baggage continuously.
IMPORTANT
This is a TRUE 90° spiral chute / quarter-turn chute.
The proposed design must NOT be a multi-turn spiral. The baggage should travel through approximately 90° in plan view, from the infeed conveyor to the discharge conveyor.
1. Application
Application: Airport Baggage Handling System
Equipment: 90° Spiral Chute
Operation: Continuous / high-duty operation
Baggage types:
• Soft luggage / fabric bags
• Hard-shell plastic suitcases
• Cardboard boxes
• Shrink-wrapped boxes
• Cling-film/stretch-wrapped baggage
• Mixed baggage
2. Baggage Parameters
Size: Baggage dimensions can vary approximately from 200 mm to 930 mm. L × W × H may vary considerably.
Weight: 10–50 kg per item. The chute must accommodate the complete range without manual intervention.
3. Existing Chute
We will provide the existing GA drawing, photographs and videos... read more

Size: Baggage dimensions can vary approximately from 200 mm to 930 mm. L × W × H may vary considerably.
Weight: 10–50 kg per item. The chute must accommodate the complete range without manual intervention.
3. Existing Chute
We will provide the existing GA drawing, photographs and videos of the actual baggage movement/jamming.
Existing chute information: Chute width: Approximately 1000 mm internal width
Clockwise Chute
• Infeed height: 3125 mm
• Discharge height: 1250 mm
Counter-Clockwise Chute
• Infeed height: 2850 mm
• Discharge height: 1250 mm
The Clockwise and Counter-Clockwise versions should preferably use a common/basic design philosophy, with the geometry mirrored where appropriate.
4. Main Problem to Solve
The major problem is baggage stopping/jamming on the chute surface. The problem is particularly severe with baggage wrapped in cling film/stretch film.
Observed behaviour:
• Baggage enters the chute.
• Some bags rotate/yaw during transition.
• The baggage may move sideways relative to the chute.
• The large flat surface of the wrapped package contacts the chute.
• High friction between the cling film and sliding surface prevents forward movement.
• The baggage eventually stops and can block subsequent baggage. Hard plastic suitcases and cloth bags generally slide much better.
5. Required Design Approach:
We do not want a solution that simply says: “Apply PTFE/Teflon coating.” The designer should evaluate the entire mechanical system. The proposed design should consider:
• Entry transition: Develop a smooth transition between the infeed conveyor and spiral chute. The transition should minimise: Impact, Bouncing, Rotation, Sudden change in direction.
• Raw Material: Mild Steel. Finish – Painted / Powder Coating
• Side Guides: The design must prevent baggage from becoming wedged between the chute and side wall and maintain baggage stability. The guide arrangement must accommodate baggage up to approximately 930 mm while still handling smaller baggage.
6. Design Validation Required: The designer should not only create a visually attractive CAD model. The design should be engineering validated. The final selection must consider: Wear resistance, Impact resistance, Airport operating environment, Maintainability, Ease of Installation and replacement and Final Cost
7. CAD Deliverables
We require professional fabrication-ready CAD documentation, not just a 3D concept.
Please provide 3D CAD model in SolidWorks
Native CAD files should be supplied wherever possible.
2D GA drawing: A proper engineering GA drawing including Plan view, Elevation, Front view, Isometric view, Section views, Detailed entry transition, Detailed discharge transition, Guide rail details, Support structure, Manufacturing drawings (Flattened Files).
Detailed drawings for: Chute body, Side walls, Transition plates, Guide rails, Brackets, Supports, Centre/Support Column, Mounting Arrangements, BOM
Complete Bill of Materials including Raw Material, Thickness, Quantity, Standard Components, Fasteners
8. Maintainability:
The chute operates continuously, so maintenance is important. The design must allow: Easy replacement, Easy inspection, Access to fasteners, Cleaning, Minimal downtime.
Expected Final Outcome
The objective is to develop a reliable, fabrication-ready 90° baggage spiral chute capable of continuously handling:
• 10–50 kg baggage
• 200–930 mm baggage size
• Easy Sliding of baggage’s including difficult Cling-film/stretch-wrapped baggage
• Without stopping
• Sideways Wedging
• Excessive Rotation
• Unacceptable impact
• Baggage damage
• Manual intervention read less
