Dockzilla® Portable Ramps & Loading Dock FAQs:

Loading Dock Construction Alternatives

How can our facility add capacity without investing in permanent loading dock construction?
Dockzilla Portable Loading Docks combine a 30’ ramp with a free-standing platform to create are the easiest, most cost-effective way to add loading dock capacity at an existing facility without the hassle or downtime of new construction. These pre-fabricated loading docks can be easily relocated to a new job site or facility. Dockzilla products can be onsite within 6-8 weeks, ready to perform the duties of a permanent loading dock, making them useful loading dock construction alternatives. They can be used indoors or outdoors based on site conditions.
How do we unload over the road trailers if we don’t have a loading dock?
Typically, companies coordinate a special delivery with a lift gate style trailer or manually unload the trailer by hand. Both of these options can be time consuming and dangerous. A Dockzilla loading dock enables companies without traditional loading docks to unload trailers in a fraction of the time, tapping the power of a forklift and the safety features found in a conventional loading dock.
How is Dockzilla a viable alternative to loading dock construction?
Dockzilla condenses the safety and performance features of a permanent loading dock into a robust, portable product built to withstand the rigors of daily trailer unloading and forklift impact loads. These colossal workhorses serve as permanent loading dock construction alternatives, which can climb to $100K-plus per dock. Dockzilla portable loading docks increase productivity by 80% over manual loading/unloading.
How can I determine if a Dockzilla portable loading dock is the right option for our application?
Delivering flexibility to the loading dock, the Dockzilla family of products is configured to address a variety of materials handling needs. Our engineers help customers select from the line-up of mobile and fixed-position ramps include: mobile yard ramps, impactable yard ramps, portable loading docks, dock to ground ramps, self-standing platforms, parcel dock ramps, and custom alternatives to permanent loading dock construction. If you can’t find an answer to your question in the loading dock FAQs, contact Leum Engineering at 1-800-637-3036 to determine the right product for your application.
How safe are these mobile ramps?
While not yet regulated by OSHA, Dockzilla portable loading docks are designed on our own recognizance with impressive safety features that meet or exceed OSHA requirements for permanent loading docks. With no comparison to rudimentary forklift ramps, we engineer our portable units with heavy-duty support legs, an integral dock leveler, handrails, and wheel chocks. Our mobile yard ramp features patents for automatic kingpin engagement and wheel placement to virtually eliminate human interaction and minimize employee effort.
What kind of companies or industries are using Dockzilla units?

Trailer Solutions:

Correcting problems caused by trailers below floor level

Why are there so many issues with loading docks?
Unfortunately many loading docks are designed and constructed improperly, and most aren’t equipped to offer a one-size-fits-all solution. The variability of trailer styles, sizes, and axle positions cause trailer bed heights to be several inches above or below dock level. Our line up of trailer solutions products were engineered specifically to remedy inferior design that impacts drainage placement, specialty trailers, or those that have shorter bed heights than the typical 48” high over-the-road trailer.
How can I fix the issues with drainage placement?
Drainage placed further away from the building can interfere with trailer configuration and negatively impact the geometry of the dock design. Unfortunately, you don’t know the drain is in the wrong location until it’s too late and the truck comes in too low for the dock. Our pit filler wheel risers are custom-built static, non-adjustable wheel risers which correct below dock conditions caused by compound decline approaches.
How do I ensure the trailer backs onto the wheel riser platform?
We have an option to weld integral wheel guides onto the deck of the wheel riser which guides the wheels and ensure that the truck backs in properly.
How do you handle snow removal?
Depending on the style of wheel riser, you must shovel to avoid ice and snow buildup. We do offer serrated bar grating that enables the snow to fall through and avoid buildup.
How do you correct trailers backing in too far below dock level to safely unload?
We have multiple risers and levelers in our wheel riser product line to tackle improper loading dock design and correct dock heights. Our loading dock experts survey the area and provide measurements so that we can deliver custom products that accommodate the application, such as static wheel risers or pit filler wheel risers.

Correcting problems caused by trailers above floor level

How can we unload trailers that come in 10” or higher above my existing loading dock?
Our hydraulic top of dock leveler installs on top of your existing building floor without need for any construction. This hydraulic ramp features simple push button operation and will service up to 18” above your building floor level.
How can we streamline the two-step process in loading/unloading delivery vans?
Most often, we see parcel delivery trucks are challenged by below-dock loading conditions that requires employees to hoist boxes two feet to the building floor and then bend over to pick up the boxes left on the dock. Leum Engineering’s parcel dock ramps eliminate these ergonomic, safety, and productivity issues by raising the truck or van so that employees can better handle and expedite packages with a trailer that is level with the building.

Rail Solutions:

Safely loading and unloading railcars

How can we bridge the loading area between our rail docks and boxcars?
A heavy duty railboard by Leum Engineering combines the structure to handle heavy forklift loads and bridge the gap between the building floor and boxcar. Built to stand up to the rigors of forklift traffic and materials handling, our railboards provide 4-inch high run off guards so forklifts don’t tip or fall into the gap.
How does a railboard handle the variation in boxcar widths?
Our railboards incorporate automatically placed D-Rings to fill the gap between the boxcar and the building floor to safely hold the plate in place.
How do I minimize damage to my costly forklift tires when loading and unloading boxcars?
Railboards are customized to accommodate the varying options and capacity by industry. To reduce tire damage, they are built with side curbs that are recessed 8-inches to allow for 90 degree turning into the boxcar, and all traffic surfaces have machine chamfered edges for a smoother transition for forklifts.
How can I guard the 4 ft. drop-off next to an indoor rail dock or indoor flatbed dock?
Dockshield Removable Forklift Dock Barriers (patent pending) provide relentless forklift and personnel safety with heavy duty steel construction, 42” guardrails, and 12” high steel forklift impact barriers. Used to safeguard heavy equipment, work zones, rail docks, and flatbed docks, Dockshield removable guardrails provide an intuitive alternative to the yellow caution paint, floor guards and other lackluster offerings on the market.
Does this barrier comply with OSHA pedestrian fall protection standards?
When it comes to employee protection, Dockshield Removable Forklift Barriers are helping safety managers meet and exceed OSHA requirements, particularly where code can be vague. These barriers exceed personnel guard code with three rail barriers positioned at 12”, 27” and 42”. Dockshield’s embedded floor sleeve reduces tripping and protects forklifts by transferring load impact forces to the concrete. They can be installed up to 16” from the dock edge allowing forklifts to traverse safely without worry of fall hazard.
Are these heavy-duty steel barriers cumbersome?
Quite the opposite. These loading dock barriers are designed with integral fork pockets that makes them easily removable, movable, and stackable by a forklift.
Won’t these barriers take up valuable aisle space?
For rail docks, Dockshield Removable Forklift Barriers are designed for installation 16” from the rail dock edge, maintaining precious floor space within the aisle.
How or where are the barriers stored?
The barriers are completely stackable, so forklifts can easily lift them and adhere barriers to a Dockshield barrier installed to the floor.
Will the structural design of Dockshield minimizes the force going into the floor?
An embedded sleeve that is installed flush to the floor to create solid ground support by transferring load impact forces to the concrete.

Rail yard loading and unloading

How is Dockzilla Rail a better option than other yard loading methods?
Dockzilla Rail is the result of combining the best features of two dynamic products — Dockzilla Portable Loading Docks and Railboards to transfer freight from boxcars to ground in exterior unloading areas. It is a specially-designed freight loading ramp that accommodates the wider side access of boxcars, provides mobility within the yard to quickly service boxcars and trucks, improve forklift driver ergonomics, and reduce costly damage to forklift tires.
How safe is Dockzilla Rail?
Built-in self-supporting legs, wheel chocks, and safety chains enable forklift drivers to focus on traversing the ramp with their heavy loads.
