This invention relates to a container for shipping snowmobiles and all-terrain vehicles (“ATVs”). These vehicles are typically shipped individually in single containers. The container consists of a base, a cage structure, and a cover. The container for shipping these machines has to be able to withstand not only the weight of the machines themselves (typically 600-900 lbs), but multiples of this weight, as up to four containers are often stacked on top of one another during shipping or storage. Because of this, the primary materials currently used to construct shipping containers for these vehicles are metal and wood.
Wood is typically used in containers for domestic, intrastate shipments of snow machines. However, most countries mandate that wood used in packaging/crating material must be heavily treated in order to prevent contamination from pests residing in the wood. The cost of treating wood usually makes its use as a structural material economically impracticable. As a result, wood is generally only used in domestic vehicle shipments due to these stringent international treatment requirements.
Structural metal is heavy, subject to corrosion and preservation issues, and also creates a waste disposal problem in certain countries. Metal container material generally becomes scrap waste after it is used. It is not easily reusable, because it is too heavy—and therefore expensive—to ship back to its origin for reuse or recycling. In addition, the vehicles shipped in metal crates often require washing and detailing before they can be placed on a showroom floor at their final destination, due to aforementioned corrosion issues (e.g. rust or other oxidation flaking from the metal cage structure onto the machines).
Containers for shipping vehicles are usually manufactured in “knocked down” form and shipped to the vehicle manufacturer, where the crate is assembled around the vehicle. Using metal and wood as structural material often lead to abrasion and other issues during final assembly at the vehicle manufacturer. Also, both wood and metal are heavy which increases the overall cost of shipping the vehicle inside the container. Finally, wood and metal both carry a high cost of materials that is very volatile due to its direct correlation with the cost of building supplies. Thus, structural material made of either metal and wood both have significant disadvantages.
The container described herein solves the problem of excess weight, corrosion, and disposal by featuring a pre-assembled cage structure, comprised of V-shaped cross sections of laminated paperboard or fiberboard, that is mounted on a wooden base to allow quick construction of the final container on a vehicle assembly line, further having a cover comprised of a special layered fabric material that is heat-shrinkable, and printable. The outer layer of the cover material is water-resistant, while the inner layer of the material is moisture wicking; i.e. the overall material tends to allow moisture from the inner layer to escape, but moisture from the outside cannot penetrate to the inner layers.
Sections of laminated paperboard or fiberboard with V-shaped cross sections have been used to provide protection for the edges of corrugated cartons or pallets during shipping. However, it was discovered that the V-shaped sections of laminated paperboard or fiberboard had sufficient structural integrity to be used as a substitute for wood or metal in vehicle shipping containers. Although the original versions of the fiberboard/paperboard lost their structural integrity when exposed to large amounts of moisture, a new water-resistant version described herein is used.
Use of the paperboard/fiberboard material dramatically reduces the weight of the overall crate, while the use of the heat-shrinkable cover material not only protects the vehicle and cage structure from the elements, but contributes significantly to the overall aesthetics of the system. The cover material used is readily printable, so the vehicle manufacturer's logo, trademarks, and other designs can appear on the outside of the container, giving the container an aesthetically attractive, “wrapped box” appearance.
The current design is viewed as revolutionary in the industry for this particular application for a variety of reasons. First, it was commonly believed that the paperboard material that is used in the current design did not possess sufficient structural strength to support the weight of several vehicle containers when stacked for shipping or storage. Thus, the customer for whom the design was originally intended was skeptical when told that the container structure was essentially made of cardboard, given that all industry standard designs used either wood or metal. Second, it wasn't commonly believed that the laminated paperboard material could retain its structural integrity when exposed to moisture, i.e. rain and snow. However, the cover material used with the design protects this structure from the elements. Moreover, a moisture-resistant version of the laminated paperboard is incorporated with the latest embodiments to confer an added measure of protection from moisture. Preliminary reaction by customers for these containers has been extremely positive, with one remarking that the current design “will change the industry”.
The container design disclosed herein features significant weight advantages over current vehicle transport container designs. A typical metal-frame vehicle container weighs 200 lbs, while a wood-frame container weighs 150 lbs. The embodiments disclosed herein weigh approximately 141 lbs, a reduction of about 30% in weight over metal and about 6% over wood crates. Shipping costs are therefore reduced considerably by the new design.
Referring now to
The base, 1, end assemblies 2, and top assembly 3 are pre-assembled and then shipped to a vehicle manufacturer in “knocked-down”, i.e. flat form. The pre-assembled crates can then be quickly and safely finished by the vehicle manufacturer. The vehicle is first secured to the base 1, usually at the end of the vehicle manufacturing line, and the end assemblies 2, and top assembly 3 then assembled around it, as described below.
In preliminary runs, it was found that the number of manufacturer personnel required to assemble the container was reduced from seven persons to five persons. Thus, the container disclosed herein also reduces the manufacturer's labor costs as well as shipping costs.
The cage structure is comprised of two end assemblies 2 and a top assembly 3, as shown in
