Product code: PT-7243 · Specification: Small steel-pipe trolley for narrow aisles

Narrow-aisle Lean Pipe Trolley 720×430×1500

Delivery: production 5–7 days; this configuration has been delivered to a connector factory in Long An (name disclosed when permitted).

A narrow trolley for moving component trays, sub-assemblies and packing boxes between line positions with aisles of 600–800 mm. Lean pipe (plastic-coated steel pipe, Φ28) frame with joints, 4–5 MDF shelves with plastic edging (ESD laminate optional), PU Φ75 castors with 4 swivel and 2 braked, single-end push handle. Light (~18 kg), can be pushed with one hand, and shelves can be added by the user.

Selection advice
– Narrow aisles, small trays → this model.
– 600×400 bins, heavy loads → 1500×600 trolley (PT-1516).
– Cleanrooms → 3030 aluminium trolley (AT-8612).
– Carrying boards upright → magazine rack (MR).

Inspection & handover: load test, brake check, inspection record; drawings supplied.

FAQ
– Will it pass through an 800 mm door? — Yes, it is 430 mm wide. Turning on the spot needs clearance larger than the trolley’s diagonal (≈ 840 mm) plus the handle — measure the actual corners.
– Can lips be added so trays don’t fall off? — Yes, 20–40 mm lips on three sides.
– Is an ESD surface available? — Yes: ESD laminate bonded to the frame by a wire/metal joint, 4 conductive castors; a drag chain is only a supplementary measure.
– Volume discounts? — From 10 trolleys the price is reduced by 8–10 %, delivered in lots.

Trolley geometry in narrow aisles

The 430 mm width determines whether the trolley fits through the aisle; the ability to turn around depends on the footprint diagonal. For a 720 × 430 mm trolley, the diagonal is approximately √(720² + 430²) ≈ 840 mm — this is the minimum diameter when rotating the trolley about its centre, not counting the handle and the swivel castors swinging outward. When surveying aisles, also measure pinch points: columns, rack legs, electrical cabinets, room doors.

4 swivel castors: turns on the spot and can move sideways — suited to narrow aisles with many corners. Drawback: hard to keep straight over long distances, so the operator must “steer” constantly.
2 swivel + 2 fixed: tracks straight and stable, less tiring; but needs more turning space. Swivel castors go at the handle end.

Stability: tall trolley, narrow base

A trolley 1,500 mm tall on a 430 mm wide base has a height-to-width ratio of about 3.5:1, so it can easily tip sideways when a castor hits a ridge or groove or during a sharp turn. Loading rules:

Heaviest items on the bottom shelf; upper shelves only for light trays, paperwork and small components.
Place trays centred on the shelf, not overhanging the edge; use lips on sides where items could fall.
Push slowly over floor ridges and door tracks; do not pull the trolley backwards when your view is blocked.

PU Φ75 castors: load per castor and push force

Polyurethane castors (hardness about 92 Shore A) have low starting and rolling resistance and leave no marks on the floor — suitable for assembly lines with epoxy floors. Castor maker TENTE recommends calculating load per castor = (trolley weight + load) ÷ (number of castors − 1), because on uneven floors only 3 castors carry the load. For a trolley of about 18 kg carrying 120 kg: (18 + 120) ÷ 3 = 46 kg/castor — replacement castors must be rated for at least this load.

Ergonomically, ISO 11228-2 and the Snook – Liberty Mutual tables separate initial force and sustained force. HSE (UK) screening figures: starting/stopping about 200 N for men, 150 N for women; sustained about 100 N for men, 70 N for women. A small trolley loaded to 120 kg on a flat floor is usually below these levels; force rises noticeably when castors are worn, jammed with debris or the floor is uneven — measure with a force gauge at the handle at acceptance and at each periodic inspection.

ESD configuration: a continuous path is required

The plastic coating on standard pipe is an insulator, so an ESD laminate surface will not ground itself through the frame. A true ESD trolley needs a continuous path: ESD shelf surface → wire or metal joint → frame → conductive castors → ESD floor → ground.

ANSI/ESD S20.20 classifies carts as mobile equipment, with a resistance-to-ground limit of < 1×10⁹ Ω.
A drag chain is a supplementary measure: its contact area is small, and many factories report unreliable grounding. Use all 4 conductive castors and plug in a ground cord when the trolley is parked at a station for long periods.
A castor touches the floor over only about 1 cm²; on ESD vinyl floors with sparse conductive chips, the same trolley may pass at one moment and fail the next just by moving a few cm. Measure at several positions during acceptance.
Measure per ESD TR53: place a 5 lb electrode on each shelf and measure to ground through the floor.

Common mistakes

Choosing a trolley by aisle width but forgetting the turning radius at corners.
Putting heavy bins on the top shelf to make them “easier to reach”.
Fitting an ESD surface but keeping standard PU castors, or using an ESD trolley on a non-conductive epoxy floor.
Not cleaning the castors: thread, tape and PE film wrapped around the axle make the trolley heavy and pull it off course.
