Abstract

Abstract A terrain-going vehicle of the forked frame type, the stem fore end being supported by a front wheel shaft, and the fork legs being at each end supported by a different rear bogie shaft; said legs having their inner ends pivoted to the frame; the rear end of the frame, extending between the two fork legs, supports a movable fundament plate, and the fore end of the frame is rotatable around its longitudinal axis with respect to the rest of the frame; a hydraulic jack forming an upstanding telescopic bar connected between each leg and an associated point on said fundament plate, the two jacks being separately operable to keep the fundament plate level, even when driving along a lateral slant in the terrain and facilitating the overcoming of ground obstacles.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 198 words
A stabilizing arrangement in terrain-going vehicles having a driver''s cabin and a rearly branched framework where the stem of the branches, constituting the frame of the vehicle, at its front end is supported by a front wheel shaft, and the branches, constituting longitudinal legs, have each of their ends supported by a different rear shaft for a bogie bar, the improvement wherein the rear end of the frame of the vehicle serves as a support for a fundament plate for receiving operation equipment, and the two longitudinal legs are pivoted in alignment with each other at each side of the frame; a separately operable hydraulic jack forming an upstanding and longitudinally variable supporting bar between each leg and an associated point on the plate in order to enable an individual raising and lowering of the rear shafts, the front part of the frame, supporting the front wheel shaft, being freely rotatable around its longitudinal axis, whereby it will be possible, on one hand, to straighten up the vehicle including the fundament plate when driving along a lateral slant in the terrain and, on the other hand, to enable a simple and gentle surmounting of obstacles on the ground.
Claim 2
Dependent Claim 198 words
A stabilizing arrangement in terrain-going vehicles having a driver''s cabin and a rearly branched framework where the stem of the branches, constituting the frame of the vehicle, at its front end is supported by a front wheel shaft, and the branches, constituting longitudinal legs, have each of their ends supported by a different rear shaft for a bogie bar, the improvement wherein the rear end of the frame of the vehicle serves as a support for a fundament plate for receiving operation equipment, and the two longitudinal legs are pivoted in alignment with each other at each side of the frame; a separately operable hydraulic jack forming an upstanding and longitudinally variable supporting bar between each leg and an associated point on the plate in order to enable an individual raising and lowering of the rear shafts, the front part of the frame, supporting the front wheel shaft, being freely rotatable around its longitudinal axis, whereby it will be possible, on one hand, to straighten up the vehicle including the fundament plate when driving along a lateral slant in the terrain and, on the other hand, to enable a simple and gentle surmounting of obstacles on the ground.
Claim 3
Dependent Claim 77 words
An arrangement according to claim 1, wherein the fundament plate is provided with a turntable for orienting the operation equipment on the plate in the plane thereof, the fundament plate itself, or a platform supported by it, forming a bearing surface for the driver''s cabin and fuel and oil tanks for all driving purposes, the driver''s cabin being provided with a remote control for the operation of work tools as well as the operation of the vehicle.
Claim 4
Dependent Claim 37 words
An Arrangement according to claim 2, wherein said fundament plate itself, or a platform by it, form a bearing surface for crane means and crane drive means and motor means for rotating the fundament plate or platform.
