Abstract
A system to stabilize a construction vehicle having a frame and a pair of stabilizing legs with ground-engaging shoes at the ends of the legs. The stabilizing legs pivotally connect to the frame on substantially opposing sides, so that the stabilizing legs pivot upwards to a stowed position and pivot downwards to a stabilizing position where the shoe engages the ground. Further, the stabilizing legs telescope between a retracted position and an extended position. The retracted position locates the shoe closer to the vehicle and the extended position locates the shoe further from the vehicle. A pair of hydraulic cylinders connect to the respective stabilizing legs to power the telescopic movement of the stabilizing legs between the retracted position and extended position.
Claims20
A system to stabilize a construction vehicle comprising:
- a frame to support the construction vehicle;
- a pair of stabilizing legs with ground-engaging shoes disposed at the distal ends of the legs;
- wherein the stabilizing legs are pivotally connected to the frame on substantially opposing sides of the frame, such that the stabilizing legs pivot upwards to a stowed position close to the vehicle and pivot downwards to a stabilizing position where the shoes engages the ground;
- wherein the stabilizing legs telescope between a retracted position and an extended position, whereby the retracted position locates the shoe closer to the vehicle and the extended position locates the shoe further from the vehicle;
- a pair of hydraulic cylinders connected to the respective stabilizing legs to power the telescopic movement of the stabilizing legs between the retracted position and extended position.
A system to stabilize a construction vehicle, which has a frame with a tractor mounted on the frame, comprising:
- a stabilizing leg with a ground-engaging shoe;
- wherein the stabilizing leg is pivotally connected to the frame, such that the stabilizing leg pivots upwards to a stowed position and pivots downwards to a stabilizing position where the shoe engages the ground;
- wherein the stabilizing leg telescopes between a retracted position and an extended position, whereby the retracted position locates the shoe closer to the frame and the extended position locates the shoe further from the frame;
- a hydraulic cylinder connected to the stabilizing leg to power the telescopic movement of the stabilizing leg between the retracted position and extended position.
A kit, which retrofits a construction vehicle with an existing hydraulic circuit, comprising:
- a pair of stabilizing legs adapted to connect to ground-engaging shoes disposed at the distal ends of the legs;
- wherein the stabilizing legs are configured and arranged to pivotally connect to the frame on substantially opposing sides of the frame, such that the stabilizing legs pivot upwards to a stowed position close to the vehicle and pivot downwards to a stabilizing position where the shoe engages the ground;
- wherein the stabilizing legs telescope between a retracted position and an extended position, whereby the retracted position locates the shoe closer to the vehicle and the extended position locates the shoe further from the vehicle;
- a pair of hydraulic cylinders connected to the respective stabilizing legs to power the telescopic movement of the stabilizing legs between the retracted position and extended position;
- and
- a diverter to divert hydraulic fluid from the existing hydraulic circuit to the pair of hydraulic cylinders.
