Abstract
Abstract A converter handling vehicle adapted to lower or raise a converter and to transport the converter in any direction along the ground. The vehicle comprises bogie trucks on each side of the vehicle, a pair of levers on each side of the vehicle, the arms intersecting and being pivotally connected to a point between the ends of the levers, the lower ends being connected to the bogie trucks, a converter holding member that is pivotally connected to the upper ends of the levers, hydraulic cylinders and piston rods connected to the levers to raise or lower the converter, a support plate rotatably mounted under the holding member to support the vehicle and the converter when the direction of travel is to be changed, and a driver to cause the converter and the vehicle to rotate about the support member to change directions when the support member supports the weight of the vehicle and converter.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
193 words
A converter handling vehicle adapted to move a converter in the vertical direction and to transport the converter in any horizontal direction along the ground comprising bogie trucks that travel along the ground, at least a pair of levers, the levers intersecting each other at a point between the ends of the levers in a generally vertical plane and pivotally joined at the intersection, an end of each of the levers further being pivotally connected to the bogie trucks, a converter holding member, the converter holding member being connected to the other ends of the levers, adjustment means connecting the lower end of one lever to the upper end of the other lever to cause the levers to rotate about the intersection and thereby lift or lower the converter, supporting means rotatively affixed to the bottom of the converter holding member to contact the ground to support the vehicle and converter when the adjustment means causes the bogie trucks to move away from the ground, rotating means for rotating the vehicle and converter about a vertical axis relative to the supporting means whereby the vehicle changes the direction of travel on the ground.
Claim 2
Dependent Claim
193 words
A converter handling vehicle adapted to move a converter in the vertical direction and to transport the converter in any horizontal direction along the ground comprising bogie trucks that travel along the ground, at least a pair of levers, the levers intersecting each other at a point between the ends of the levers in a generally vertical plane and pivotally joined at the intersection, an end of each of the levers further being pivotally connected to the bogie trucks, a converter holding member, the converter holding member being connected to the other ends of the levers, adjustment means connecting the lower end of one lever to the upper end of the other lever to cause the levers to rotate about the intersection and thereby lift or lower the converter, supporting means rotatively affixed to the bottom of the converter holding member to contact the ground to support the vehicle and converter when the adjustment means causes the bogie trucks to move away from the ground, rotating means for rotating the vehicle and converter about a vertical axis relative to the supporting means whereby the vehicle changes the direction of travel on the ground.
Claim 3
Dependent Claim
193 words
A converter handling vehicle adapted to move a converter in the vertical direction and to transport the converter in any horizontal direction along the ground comprising bogie trucks that travel along the ground, at least a pair of levers, the levers intersecting each other at a point between the ends of the levers in a generally vertical plane and pivotally joined at the intersection, an end of each of the levers further being pivotally connected to the bogie trucks, a converter holding member, the converter holding member being connected to the other ends of the levers, adjustment means connecting the lower end of one lever to the upper end of the other lever to cause the levers to rotate about the intersection and thereby lift or lower the converter, supporting means rotatively affixed to the bottom of the converter holding member to contact the ground to support the vehicle and converter when the adjustment means causes the bogie trucks to move away from the ground, rotating means for rotating the vehicle and converter about a vertical axis relative to the supporting means whereby the vehicle changes the direction of travel on the ground.
Claim 4
Dependent Claim
193 words
A converter handling vehicle adapted to move a converter in the vertical direction and to transport the converter in any horizontal direction along the ground comprising bogie trucks that travel along the ground, at least a pair of levers, the levers intersecting each other at a point between the ends of the levers in a generally vertical plane and pivotally joined at the intersection, an end of each of the levers further being pivotally connected to the bogie trucks, a converter holding member, the converter holding member being connected to the other ends of the levers, adjustment means connecting the lower end of one lever to the upper end of the other lever to cause the levers to rotate about the intersection and thereby lift or lower the converter, supporting means rotatively affixed to the bottom of the converter holding member to contact the ground to support the vehicle and converter when the adjustment means causes the bogie trucks to move away from the ground, rotating means for rotating the vehicle and converter about a vertical axis relative to the supporting means whereby the vehicle changes the direction of travel on the ground.
Claim 5
Dependent Claim
33 words
The converter handling vehicle according to claim 1, further comprising at least two guiding levers, the guiding levers pivotally connecting the one end of each of the levers to the converter holding member.
Claim 6
Dependent Claim
25 words
The converter handling vehicle according to claim 1, wherein the adjustment means comprise hydraulic cylinders and extensible piston rods which are connected to the levers.
Claim 7
Dependent Claim
19 words
The coNverter handling vehicle according to claim 3 wherein the piston rods are connected to the levers by straps.
Claim 8
Dependent Claim
30 words
