Liftgates generally is a boon to a truck fleet — however spec the incorrect liftgate for the truck and software, and the liftgate could ship complications as an alternative of products.
There are numerous issues that may go incorrect when specifying a raise. Gates may not decrease all the best way, making it not possible to roll a pallet jack or handcart onto the raise platform. When loaded, the truck could sit too low, stopping a tuckaway liftgate from reducing and unfolding. Battery energy may run low alongside the truck’s route, requiring a recharge (or inflicting a service name) that delays deliveries.
Listed below are the highest 10 issues to think about when specifying a liftgate that features as meant.
“The products you ship, the place you ship them, and what number of deliveries and pickups you will have each day are going to dictate a lot of the [liftgate power need and battery recharge] spec,” says Kevin Otto, the electrification technical lead on the North American Council for Freight Effectivity. And that’s true not only for energy wants however for the liftgate spec as an entire.
1. Take into account the Software
Liftgates increase and decrease freight from the again of the truck to the bottom and vice versa. However some liftgates work higher in particular functions than others.
Take into account how the liftgate shall be used. What sort of cargo will the liftgate deal with? What’s the size, width, and peak of that cargo? How heavy is it? The solutions to those questions will have an effect on the kind of liftgate specified.
There are numerous variations between shifting crops, automotive components, grocery merchandise, drinks, batteries and bakery merchandise.
Choose a liftgate to deal with the load of the appliance. Maxon Carry designed the BMR Columnlift for heavy-duty functions with masses as much as 6,600 kilos.

“It’s actually in regards to the software,” says Arnold Kowal, director for after gross sales service assist at Maxon Carry. “The gate spec relies on the appliance. How a lot does a product weigh and the way massive is it? If a product is tall or high heavy, you want a level-ride liftgate, so the merchandise don’t tip over.”
2. Appropriately Calculate Weight
“A key consideration is how a lot complete weight you wish to decrease and lift with the liftgate,” says NACFE’s Otto, who spent 40 years at Cummins, the place he led a number of enterprise items.
A truck delivering 2,000 to three,000 kilos of products is not going to require a liftgate with a 6,000-pound capability. However when calculating weight masses, it’s important to consider product weight, the load of the gear used to maneuver the product, and the load of the motive force.

Pallet jacks, dollies or carts may improve capability weights by 100 to 1,000 kilos. Many drivers will leap on the liftgate, which can also improve weight by 200 kilos or extra. The appropriate liftgate have to be rated to deal with this further weight.
“It’s a must to calculate the load of every little thing that shall be on the liftgate. That features the motive force, the jack, and the pallet,” says Anton Griessner, vice chairman of selling and enterprise improvement at Maxon. “An electrical pallet jack alone may weigh 1,000 kilos or extra. It’s possible you’ll overload the gate when you don’t spec for it.”
3. Get a Liftgate Spec’d for the Car
The kind and dimension of the automobile additionally impacts liftgate choice. As a rule of thumb, specify the biggest liftgate the supply automobile can deal with. Liftgate choice will depend on the kind of automobile, from pickup truck to straight truck, van to tractor-trailer. Liftgate width and platform sizes are decided by automobile width.

Issues can happen if a automobile wants a hitch to tug a trailer. The hitch could impede platform operation. The liftgate specification ought to account for the hitch. It may value quite a bit to vary this later.
When spec’ing a liftgate for a trailer, the kind of trailer impacts liftgate choice. Smaller and medium-duty liftgates should not designed for the pounding a trailer can provide them.
“There are particular fashions for particular sorts of autos and particular sorts of trailers,” Griessner says.
4. Select the Proper Sort of Door
The door sorts on vans or trailers can also have an effect on liftgate choice.
The least costly choice for many vans is a swing-open door, which has extra peak clearance than a roll-up door. Nonetheless, these doorways are incompatible with rail-style gates, which mount on the skin nook posts of the truck physique, the place the hinges for the swing door are already positioned.

“The hinge can forestall a rail-style gate from being hooked up. The door swings by way of that space and latches onto the skin of the physique,” Griessner says.
Tuck-away or cantilever gates can work greatest with swing-open doorways and supply the biggest platforms in these conditions.
5. Take into account Laden Versus Unladen
One other space that may trigger issues is truck mattress peak. Placing a tuckaway liftgate beneath a truck that lacks the loaded mattress peak clearance for that gate may forestall the gate from opening or touching the bottom.
The phrases laden and unladen measure the clearance of the truck with and with out a load. It’s attainable to specify a liftgate that doesn’t attain the bottom or can’t be totally prolonged if fleet managers don’t perceive these phrases. Laden describes when a truck is totally loaded with supplies, making it sit decrease to the bottom, whereas unladen refers to a truck that’s empty, and sits greater off the bottom.
It’s essential to know the very best level of the truck when it’s unladen to correctly specify a liftgate. That is the utmost peak the liftgate wants to have the ability to attain. Deciding on a liftgate based mostly on laden peak, the peak of the truck when it sits decrease to the bottom, might end in a liftgate that doesn’t attain the bottom.
It’s equally necessary to think about truck peak when it’s totally laden, or at its lowest level, which dictates minimal clearance necessities.
Each truck mannequin has its personal laden and unladen peak dimensions based mostly on its physique specs. This data can be utilized as a reference to information liftgate choice.
6. Know Thy Gates
There are 4 widespread sorts of liftgates, every with its personal execs and cons. They’re:
- Tuck-under
- Rail- or column-lift
- Cantilever
- Slider
Tuck-under liftgates (additionally referred to as stow-away and related names) keep out of the best way till they’re wanted. They tuck beneath and away from the cargo entrance, so the truck can again as much as loading docks with out the liftgate getting in the best way. These liftgates tilt to kind a ramp, making it straightforward to roll cargo into and out of the truck.
Rail liftgates stow flat towards the rear of the truck or trailer physique when not in use. When loading and unloading heavy objects on the road, they’ve a platform that’s giant and stage. The design of those liftgates ensures they keep aligned with the truck mattress throughout use, retaining issues stage. Nonetheless, they are often impractical as a result of they cowl a part of the rear doorway when not in use and therefore must be lowered down at each cease.
Cantilever liftgates maintain cargo stage throughout loading and unloading and provide exceptionally giant platforms (in actual fact, the platform in some functions can take the place of a rear door). Customers can change the lean of the platform to maintain it stage. Most cantilever liftgates include foot controls to energy them up or down. They’ve design choices which can be appropriate with carts and pallets.
The film trade usually makes use of cantilever-type liftgates as a result of they maintain crates and delicate gear stage because the gate strikes up and down, says Maxon Carry’s Kowal, who provides, “Each trade has a specific mannequin gate that works greatest for it.”
Some producers additionally provide slider liftgates that stow horizontally beneath a truck or trailer. Cantilevers and sliders are usually utilized in area of interest functions.
Mild-duty liftgates are additionally out there. These liftgates are greatest for gentle to average masses and work effectively on pickup vans, service and van our bodies, and cargo vans.
“There are a ton of various liftgate configurations out there,” NACFE’s Otto says. “Fleets have to determine which configurations are greatest for his or her operations.”
7. Perceive Platform Experience
The incorrect platform experience sample can also trigger issues.
“Every experience sort meets a special set of fabric dealing with necessities,” Griessner says.
As an example, tuck-under liftgates tilt barely when the arms attain the bottom to permit operators to roll issues on and off (level-ramping experience or conventional experience). Rail-lift gates have a flat floor from the mattress to the bottom. In both case, inquire whether or not it’s a level-ride or a standard-ride platform. A level-ride platform stays stage with the truck mattress because the liftgate raises and lowers. A normal-ride platform tilts barely to kind a ramp. The kind of load, terrain, and extra are elements that decide which can work greatest.
Most liftgates have level-ramping or level-ride platforms, which keep completely stage and flat as they go up and down. These platforms present larger stability, particularly with top-heavy or tall masses. However issues come up when loading and unloading cargo on sloped floor as a result of level-ride platforms don’t regulate to those inclines. A level-ramping experience may be higher for loading and unloading in unlevel areas.
8. Spec Satisfactory Platform Depth
When fleets overlook platform dimensions, they might wind up with a liftgate that may deal with load weights however lacks sufficient area for the cargo, the gear, and the motive force.
The platform have to be giant sufficient to deal with exact cargo dimensions, together with packaging; the handcart or pallet jack; and the motive force standing on the platform. The common liftgate can deal with freight equal to or lower than 96 inches vast and 48 inches deep.
9. Plan for Energy
“Liftgates take quite a lot of amps to function when they’re shifting,” says Otto. “They use a bunch of energy in a really quick time. It may take 200 to 300 amps to function a liftgate. Any liftgate system is usually going to want auxiliary batteries to handle that prime amperage output.”
Fleets that plan to make use of auxiliary batteries should decide find out how to cost them. There are a number of methods to cost batteries and different issues to think about when calculating the variety of batteries wanted. Climate and local weather, lifts per day, how the gate shall be used, and the gap between stops (charging time) are all issues that have to be factored in. These issues decide what number of batteries are wanted and dictate the easiest way to cost them.
Otto says fleets can restrict battery drain by retaining the batteries near the liftgate. The system, he says, will lose 1-2 volts to resistance if there’s a 20- to 30-foot run from the alternator to the again of the truck.
Good controls on liftgates that alert customers to low batteries additionally may help management battery drain. Fleets ought to know the variety of cycles accomplished in a supply day. The truck will blow by way of batteries rapidly if a fleet does 30 cycles a day. Right here, they should add devoted batteries and probably a boosting cost system to increase battery life.
Historically, fleets have used Group 31 batteries to ship liftgate energy. However the growing prevalence of anti-idling legal guidelines problem the flexibility to satisfy the charging wants of those batteries. If vans can’t idle when stationary, and there’s not sufficient drive time between deliveries, retaining batteries charged turns into an issue, says Otto, who has researched the advantages of utilizing solar energy in trucking fleets for NACFE.
“Anti-idle legal guidelines and the inflated value of diesel restrict the time the alternator runs,” Kowal says. “Now it isn’t enough to replenish the vitality the liftgate has taken out in the course of the day. That’s why so many purchasers are looking for supplemental sources of recharge, photo voltaic being considered one of them. Photo voltaic is a standalone system, that means nothing needs to be operating. The provision of daylight determines how a lot vitality is put again into batteries.”
Railgates, comparable to this TVLR Sequence from Thieman Tailgates, are basic objective liftgates designed to be used on van and stake our bodies, cutaways and step-vans.

Griessner emphasizes the important thing problem has at all times been how batteries get recharged. More often than not, fleet autos recharge the batteries by distributing the facility they’ve on the observe. “However photo voltaic,” he says, “provides an extra energy supply.”
So long as the solar is shining, Otto says photo voltaic panels give a big quantity of amps to cost the batteries. He says photo voltaic panels ship a trickle cost that retains batteries topped off. Otto warns if batteries go fully lifeless alongside the route, it would shorten their life.
“Protecting batteries charged as excessive as attainable always is a good suggestion,” he says, noting that photo voltaic charging can prolong battery life by 50% or extra.
10. Plan for Longer Lifecycles
A high consideration with each fleet is gear lifecycle. Many fleets function supply vans till their upkeep wants make it value prohibitive. A decade in the past, that may have been 5 to 7 years. However with advances in expertise, many vans stay in service for over a decade — and liftgates should final simply as lengthy.
Deciding on a liftgate that makes use of galvanized metal versus paint-coated metal can prolong liftgate life. Zinc oxide is used to coat galvanized metal to stop oxidation that may weaken it. Paint-coated metal, in distinction, can corrode extra rapidly as paint chips off when the liftgate scrapes the bottom.

Liftgates constructed out of aluminum are one other different that will increase liftgate longevity. The lighter weight materials can cut back liftgate weight by as a lot as one-third, which may cut back gasoline financial system and enhance freight effectivity. Aluminum, although pricier than metal, can be corrosion resistant.
A lot rides on spec’ing the precise liftgate. Supply delays, security dangers and dissatisfied prospects may end up from the incorrect liftgate determination. However the precise liftgate helps fleets ship items reliably, effectively and safely. Attain out to your liftgate specialist earlier than you make a remaining determination.
