Dock height box truck vs liftgate: which freight each one gets

A dock height box truck and a liftgate box truck can be the same 26 ft truck; the difference is what happens at the back door. One meets a loading dock floor to floor. The other brings freight down to the ground. Which one you have, or whether you have both, decides which loads you can take, how long each stop takes, and how much payload you give up.

What is dock height on a box truck?

Dock height means the cargo floor sits about level with a loading dock. Dock equipment maker Blue Giant says the most common dock height is 48 to 52 in, and Pentalift puts it at 48 to 50 in, with truck and trailer beds arriving at about 46 to 52 in. Penske lists its 26 ft box trucks at about 46 to 50 in of floor height. That overlap is why most 26 ft trucks on a medium-duty chassis count as dock-high: back up, the dock plate drops, and a pallet jack rolls straight in.

Smaller box trucks on van chassis sit lower and usually need a ramp or a liftgate, which is one reason freight brokers treat the 26-footer as the standard box truck. If you want the rest of the 26 ft measurements, they are in the box truck sizes chart.

When a box truck's dock height doesn't match the dock

Docks have levelers to bridge small gaps, but a big height difference turns the leveler into a steep ramp. Blue Giant gives the maximum grade as 10 percent for electric handling equipment and 15 percent for gas or diesel.

A loaded truck sits lower than an empty one, so a truck that meets the dock perfectly at pickup can be an inch or two low at the end of a heavy unload. Measure your floor height empty and loaded once, and tell receivers if you are unusual.

Which freight each setup gets

	Dock height only	With a liftgate
Distribution centers and warehouses	Yes	Yes (tuck-under gates)
LTL terminals and cross-docks	Yes	Yes
Retail stores without a dock	No, unless the store has a forklift	Yes
Residential and small business deliveries	No	Yes
Job sites and construction supply	No	Yes
Trade shows and events	Sometimes	Yes
Amazon Relay box truck loads	No: Relay's FAQ lists box trucks with a tuck-under liftgate	Yes, with a tuck-under gate

Load postings rarely say "no dock." They say liftgate required, LG or residential. Without a gate, you skip those posts. With one, you can take them and the dock-to-dock freight too. Our full guide to box truck liftgate loads covers gate types, capacities and safety.

Pay differences

• Dock-to-dock loads are the bulk of box truck partials and LTL. They move fast at each end and usually carry no extra charges.
• Liftgate loads often come with a liftgate charge on the rate con because the shipper pays for liftgate service. They also take longer: lowering each pallet, rolling it to the door, sometimes inside delivery. Price the time, not just the miles.
• Mixed days pay best for many 26 ft trucks: a dock pickup at a warehouse in the morning, then store deliveries by liftgate in the afternoon.

There is no published standard liftgate amount we could verify, so we don't quote one. Ask the broker to list the liftgate line on the rate confirmation before you accept, and run the full stop time through the load profit calculator.

Equipment costs and trade-offs

	Dock height only	Liftgate added
Purchase cost	Base truck	Gate plus installation; get an installed quote
Payload	Full	Lower by the gate's installed weight
Maintenance	Box and door	Plus hydraulics, batteries, chains or cables
Dock access	Full	Full with tuck-under; limited with some rail and cantilever gates
Freight you can take	Dock freight	Dock freight plus non-dock deliveries

Maxon's tuck-under TE-25 and TE-30 gates, for example, are rated at 2,500 and 3,000 lb with platforms up to 52 by 80 in. Whatever gate you choose, weigh the truck with it installed, because every pound of gate is a pound of freight you can't haul.

Which should you run?

Our view from the dispatch desk: for a 26 ft truck hauling freight, a tuck-under liftgate gives you both. The truck stays dock-high for warehouse loads and still takes the residential and store deliveries a dock-only truck has to pass on. The exception is an owner who only runs dock-to-dock linehaul, where the gate is weight carried for nothing.

Either way, set up your truck profile honestly: floor height, gate type, gate capacity and real payload. That is what we use when our box truck dispatchers search and negotiate loads for you, and it is why a load that needs a liftgate never reaches a truck without one.
