A loading dock is where goods cross between the warehouse and a truck. It sounds simple, but docks are one of the hardest things to add to a building later, and too few of them limits throughput no matter how much floor space you lease. Two kinds of loading position matter in Latvian warehouses: docks with levellers and drive-in doors at floor level.
Docks with levellers
A dock with a leveller is a door in the wall, usually about 3.0 m wide and 3.0 m high, with the warehouse floor raised to roughly 1.2 m above the yard. That is close to the bed height of a semi-trailer or a large lorry. The dock leveller is a hinged steel platform that bridges the gap and the height difference, so a forklift or pallet truck can drive straight into the trailer.
- Hydraulic levellers raise and lower with a pump at the push of a button. They suit frequent loading and heavy forklifts.
- Mechanical levellers are lifted by hand or by spring. They are cheaper to buy, but slower and more tiring at high volumes.
- Operating range matters more than the type. A standard leveller covers about 30 cm above and below dock height. Vans and small lorries sit lower, often 0.5–0.8 m, and fall outside that range.
For the purchase and maintenance costs of each type, see Hydraulic vs Mechanical Dock Levellers.
Dock shelters or inflatable seals close the gap between the truck and the building. In a Latvian winter they cut heat loss at every opening, and for chilled or frozen goods they are part of the cold chain.
Drive-in doors
A drive-in door sits at yard level, typically 4 m wide and 4.5 m high or larger, so a lorry, van or forklift can drive into the building. It suits vans and small lorries, oversized goods, and operations where forklifts load trucks from the side or the rear on the yard. It does not let a forklift drive onto a trailer bed; for that you need a dock, a mobile yard ramp or a truck with its own tail lift.
Most Class A units combine both: several docks and one or two drive-in doors. Older Class B and C buildings often have only drive-in doors, which limits how fast full trailers can be handled.
How many loading positions you need
The rule of thumb for Riga warehouses is one dock per 1,000–1,500 m² of warehouse space. It is a starting point for comparing buildings, not a design figure. Size your own need from the busiest hour:
- Count trucks arriving in your peak hour, inbound and outbound.
- Estimate handling time per truck. A full trailer of 33 Euro pallets often takes 30–45 minutes with a forklift, and longer with loose cartons.
- Docks needed = peak trucks × handling time ÷ 60 minutes, then add a buffer for late arrivals.
Example: four trucks in the peak hour at 45 minutes each need 4 × 45 ÷ 60 = 3 docks, plus one in reserve, so 4. A 3,000 m² unit at the rule-of-thumb ratio has only 2–3. A business with that peak needs more docks than the building's share, or a booking system that spreads arrivals.
Cross-docking and parcel operations need far more positions than storage-heavy operations, sometimes one per 300–500 m².
Yard and access
The yard often sets the real limit. An articulated truck is about 16.5 m long and needs roughly 35 m of clear yard depth in front of the docks to manoeuvre. Check:
- whether the docks and yard are exclusive to your unit or shared with neighbours;
- where trucks wait, and whether there is parking for trailers overnight;
- turning circles at the gate and on the access road;
- separation of trucks from cars and pedestrians.
What to check at a viewing
- Number of docks and drive-in doors allocated to your unit, in writing.
- Leveller type, capacity in tonnes, operating range and service records.
- Door sizes and dock height, compared with the vehicles you actually use.
- Dock shelters or seals, and whether the doors are insulated.
- Yard depth, truck parking and whether access is shared.
Docks and yard shape the cost of every pallet you move, so weigh them alongside clear height and rent when you compare offers.
