Abstract
Abstract A method of protecting a roadway maintenance or construction site in which a crash cushion is suspended beneath a straddle carrier-type vehicle. The crash cushion preferably comprises an inertial system of free standing sand filled plastic containers or other suitable impact attenuator which in some cases is used with a backup structure. The vehicle is connected to a towing vehicle and is towed to the maintenance or construction site or can also be used in a self-propelled configuration. When the crash cushion is located in a position to block oncoming traffic at the site, it is lowered onto the roadway and disconnected from the straddle carrier-type vehicle. The towing vehicle and straddle carrier-type vehicle can then be removed from the site leaving the crash cushion in a fixed and favorable position relative to oncoming traffic.

Independent Claim
79 words
A method of protecting a roadway maintenance or construction site, comprising, in combination: releasably suspending a crash cushion beneath a vehicle; moving said vehicle with the crash cushion suspended therefrom to the site; positioning the vehicle such that the crash cushion will block oncoming traffic at said site; depositing the crash cushion on the roadway at the site; detaching said crash cushion from the vehicle while the cushion is on said roadway; and removing the vehicle from the site.
Claim 2
Independent Claim
79 words
A method of protecting a roadway maintenance or construction site, comprising, in combination: releasably suspending a crash cushion beneath a vehicle; moving said vehicle with the crash cushion suspended therefrom to the site; positioning the vehicle such that the crash cushion will block oncoming traffic at said site; depositing the crash cushion on the roadway at the site; detaching said crash cushion from the vehicle while the cushion is on said roadway; and removing the vehicle from the site.
Claim 3
Dependent Claim
49 words
A method of protecting a roadway maintenance or construction site as defined in claim 1, which further comprises releasably suspending beneath the vehicle a crash cushion composed of free-standing frangible containers and an expendable easily dispersed mass within said containers for absorbing momentum transferred by an impacting errant vehicle.
Claim 4
Dependent Claim
34 words
A method of protecting a roadway maintenance or construction site as defined in claim 1, wherein the vehicle with crash cushion releasably suspended therefrom is towed to the site by a powered towing vehicle.
Claim 5
Dependent Claim
26 words
A method of protecting a roadway maintenance or construction site as defined in claim 1, wherein the vehicle with crash cushion releasably suspended therefrom is self-propelled.
Claim 6
Independent Claim
77 words
A method of protecting a roadway maintenance or construction site, comprising, in combination: releasably suspending a crash cushion beneath a self-propelled straddle carrier vehicle; moving said vehicle with the crash cushion suspended therefrom to the site; locating the vehicle in a position so as to block oncoming traffic at said site; depositing the crash cushion on the roadway by lowering said cushion thereon; detaching the crash cushion from the vehicle; and removing the vehicle from the site.
Claim 7
Independent Claim
77 words
A method of protecting a roadway maintenance or construction site, comprising, in combination: releasably suspending a crash cushion beneath a self-propelled straddle carrier vehicle; moving said vehicle with the crash cushion suspended therefrom to the site; locating the vehicle in a position so as to block oncoming traffic at said site; depositing the crash cushion on the roadway by lowering said cushion thereon; detaching the crash cushion from the vehicle; and removing the vehicle from the site.
Claim 8
Dependent Claim
28 words
A method of protecting a roadway maintenance or construction site as defined in claim 5 wherein the crash cushion is hydraulically lowered from the vehicle onto the roadway.
Claim 9
Dependent Claim
35 words
A method of protecting a roadway maintenance or construction site as defined in claim 5 wherein the crash cushion is lowered onto the roadway by pivoting the wheels of the vehicle relative to its carrier.
Claim 10
Independent Claim
88 words
A method of protecting a roadway maintenance or construction site, comprising, in combination: releasably suspending a crash cushion from one or more load carrying members of a wheeled straddle carrier vehicle; moving said vehicle with the crash cushion suspended therefrom to the site; locating the crash cushion in a position to block oncoming traffic at said site; depositing the crash cushion on the roadway at the site; detaching the crash cushion from the vehicle while the cushion is on said roadway; and removing the vehicle from the site.
Claim 11
Independent Claim
