Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
Load lifting and transporting apparatus, comprising: a vehicle having a lift mechanism at one end operable to lift an object from a rest position on the surface over which the vehicle travels to an elevated position and to lower said object from said elevated position; and a mobile support member mounted on said vehicle, said member being selectively movable relative to said vehicle to an extended position below an object elevated by said lift mechanism whereby said object may be deposited and supported thereon during transport movements of said vehicle, said lift mechanism comprising a selectively operable fork lift arrangement, said mobile support member being supported by at least one wheel which rolls on the same surface as the wheels of the vehicle and said support member being connected to said vehicle during movement to and from the loading position under the fork and during the depositing of a load thereon.
Claim 2
Dependent Claim
151 words
Load lifting and transporting apparatus, comprising: a vehicle having a lift mechanism at one end operable to lift an object from a rest position on the surface over which the vehicle travels to an elevated position and to lower said object from said elevated position; and a mobile support member mounted on said vehicle, said member being selectively movable relative to said vehicle to an extended position below an object elevated by said lift mechanism whereby said object may be deposited and supported thereon during transport movements of said vehicle, said lift mechanism comprising a selectively operable fork lift arrangement, said mobile support member being supported by at least one wheel which rolls on the same surface as the wheels of the vehicle and said support member being connected to said vehicle during movement to and from the loading position under the fork and during the depositing of a load thereon.
Claim 3
Dependent Claim
180 words
Load lifting and transporting apparatus, comprising: a vehicle having a lift mechanism at one end operable to lift an object from a rest position on the surface over which the vehicle travels to an elevated position and to lower said object from said elevated position; a mobile support member mounted on said vehicle, said member being selecTively movable relative to said vehicle to an extended position below an object elevated by said lift mechanism whereby said object may be deposited and supported thereon during transport movements of said vehicle; said lift mechanism including cradle means on said mobile support member for receiving and stably supporting said object selectively deposited thereon; and said lift mechanism including a fork portion providing partial support for the object deposited in the cradle means, said mobile support member being supported by at least one wheel which rolls on the same surface as the wheels of the vehicle and said support member being connected to said vehicle during movement to and from the loading position under the fork and during the depositing of a load thereon.
Claim 4
Dependent Claim
180 words
Load lifting and transporting apparatus, comprising: a vehicle having a lift mechanism at one end operable to lift an object from a rest position on the surface over which the vehicle travels to an elevated position and to lower said object from said elevated position; a mobile support member mounted on said vehicle, said member being selecTively movable relative to said vehicle to an extended position below an object elevated by said lift mechanism whereby said object may be deposited and supported thereon during transport movements of said vehicle; said lift mechanism including cradle means on said mobile support member for receiving and stably supporting said object selectively deposited thereon; and said lift mechanism including a fork portion providing partial support for the object deposited in the cradle means, said mobile support member being supported by at least one wheel which rolls on the same surface as the wheels of the vehicle and said support member being connected to said vehicle during movement to and from the loading position under the fork and during the depositing of a load thereon.
Claim 5
Dependent Claim
173 words
Load lifting and transporting apparatus, comprising: a vehicle having a lift mechanism at one end operable to lift an object from a rest position on the surface over which the vehicle travels to an elevated position and to lower said object from said elevated position; and a mobile support member mounted on said vehicle, said member being selectively movable relative to said vehicle to an extended position below an object elevated by said lift mechanism whereby said object may be deposited and supported thereon during transport movements of said vehicle, said mobile support member being mounted on at least one pair of wheels and being retractable into the vehicle assembly for travel therewith when not being used in support of an object, said mobile support member being supported by at least one wheel which rolls on the same surface as the wheels of the vehicle and said support member being connected to said vehicle during movement to and from the loading position under the fork and during the depositing of a load thereon.
