what is side loading

What Does Side Loading Mean in Freight Transport?

Side loading means goods pass through the side of the vehicle body rather than its rear doors, which puts the whole deck length within a forklift's reach at once.

Opening one side of a 13.6 m semi-trailer exposes all 33 Euro pallet positions together. Rail wagons with sliding walls apply the same idea, but this article stays with road freight.

Docks, ramps and unloading points all describe how a vehicle meets a building. Side loading is the access method among these logistics operations terms that relies on a machine alone, with no structure placed against the vehicle.

The same two words also label a software practice.

Is Side Loading the Same as Sideloading Apps?

No. Sideloading an app means installing software from outside an official app store, a practice involving phones and tablets, not vehicles or cargo.

Freight paperwork uses the term in one sense only. Carrier booking forms, transport orders and contracts written in European freight terminology apply side loading to the open side of a truck, trailer or wagon and the forklift or crane working through it.

Side access in freight starts with the body built onto the chassis.

Which Vehicles Allow Side Loading?

6 body types give side access: curtainsiders, sliding-roof curtainsiders, drop-side trucks, flatbeds, box bodies with side doors and wing-body trucks.

• Curtainsider (tautliner): fabric curtains on roof rails close both sides. A rigid headboard and rear doors mean the same trailer also takes rear loading.
• Sliding-roof curtainsider (Edscha type): the roof opens along rails, adding crane access from above.
• Drop-side truck: side boards hinge down to expose the deck for bricks, blocks and steel.
• Flatbed: no sides at all, so forklifts and cranes work from any edge.
• Box body with side doors: a rigid body with one or more side doors for quick single-pallet access.
• Wing-body truck: hydraulic side panels lift upwards. The design is common in Asia and rare in Europe.

Refrigerated curtainsiders pair insulated curtains with a cooling unit, which gives chilled goods side access as well.

All 6 bodies open through a similar sequence on site.

How Does Side Loading Work Step by Step?

A side load follows 5 steps: securing the vehicle, opening the side, clearing obstructions, placing the cargo and closing the body under tension.

1. Secure the vehicle. The vehicle stands on firm, level ground with the parking brake on, wheel chocks fitted and cones around the working zone.
2. Open the side. Buckles come off the side rail, the rear tensioner is released and the curtain is drawn back.
3. Clear obstructions. Side stakes standing in a pallet's path are lifted out and set aside for refitting.
4. Place the cargo. Pallets go in tight against the headboard and against each other across the deck.
5. Close under tension. Stakes return, buckles are hooked and pulled down, and the tensioner draws the curtain tight.

Each step maps onto the wider loading meaning of placing, positioning and securing goods before departure. The curtain simply replaces the rear doors as the way in.

Those steps assume the site has the right machine and room to use it.

What Equipment and Space Does Side Loading Need?

Side loading needs a lifting machine that reaches a trailer deck about 1.2 m high, and a firm yard with clear space along the vehicle's open side.

• Counterbalance forklift: handles standard pallets from ground level.
• Telescopic handler: places goods at the far edge of the deck without moving to the other side.
• Crane: lifts long or heavy items onto flatbeds and sliding-roof bodies.

Pallet trucks, manual or electric, are ruled out because their forks rise only a few centimetres. The yard surface must bear a loaded forklift beside the trailer, with turning room alongside.

The curtain itself then raises a securing question.

Is the Curtain a Load Restraint?

Only a body certified to EN 12642 code XL uses its curtain as part of the load restraint, and only for cargo packed tight against the curtain and walls.

A code L curtain shields goods from weather without holding them, so straps or blocking secure the whole load. An XL body is tested to withstand 40% of the payload on each side wall, 50% on the headboard and 30% on the rear doors.

Carriers keep the XL certificate with the trailer as proof of that rating. Any restraint the body does not supply is calculated under EN 12195-1. Tall, stable loads such as drinks pallets need fewer straps on an XL body.

Restraint is one trade-off among the factors that decide whether side loading fits a shipment.

What Are the Advantages and Limits of Side Loading?

Side loading gives free access along the deck and works away from buildings. In return, the cargo meets the weather while the side is open, and fabric protects it less than steel.

• Advantages:
  • Individual pallets come off at any stop without moving the others.
  • Timber, pipes and profiles go on flat instead of being angled through doors.
  • 2 forklifts can work opposite sides at the same time.
• Limits:
  • Rain and wind reach goods during handling.
  • A blade cuts a curtain faster than a steel wall.
  • Forks catch curtains and buckles.
  • The delivery address also needs a forklift and yard space.

Rear access shows those trade-offs most clearly.

How Is Side Loading Different from Rear Loading?

Side loading reaches cargo along the vehicle from ground level, while rear loading reaches it through the back doors from a dock or tail-lift.

Curtainsiders keep rear doors too, so back-door loading remains available at warehouses where the trailer reverses onto a dock.

The goods and the collection site settle which access fits.

Which Goods and Shipments Suit Side Loading?

Palletised and long goods collected from yards without docks suit side loading, including building materials, drinks, machinery, steel and timber.

Plants and builders' merchants loading from open yards fill whole curtainsiders by forklift. Booking full load freight from Belgium puts one dedicated curtainsider at the plant, carrying only that sender's goods to its EU destination.

Multi-collection rounds benefit too. The driver opens just the curtain section beside free deck space and adds pallets at each stop.

Each of these cases begins with the site details at booking.
