Abstract

1,207,492. Counterbalancing apparatus. B & S HYDRAULICS Ltd. 4 Dec., 1967 [22 Dec., 1966; 3 Feb., 1967], Nos. 57473/66 and 5367/67. Heading B8B. A device attached to one side of a vehicle for counterbalancing a load lifted by apparatus attached to the other side of the vehicle, comprises an arm 3 pivoted at 4 to the vehicle and having a counterbalance weight 13 slidably mounted thereon, the weight being arranged to slide up the arm as the arm is pivoted outwardly from the vehicle. The weight 13 is carried on a platform 8 roller-mounted in grooves in the arm 3, the platform being moved up the arm 3 by a cable 11 having one end secured to the platform and the other end secured to a point 12 of the vehicle, the cable intermediate its ends passing over a pulley 10 at the top of the arm 3. The arm is pivotally moved as desired by an hydraulic ram 6 coupled between arm and vehicle. In a further embodiment, the weight is moved along the arm by hydraulic rams.
