  • Patent number: 4476966
    Abstract: An apparatus for controlling hoist control lever velocity on hydraulic cranes. The device is connected to the hoist control lever via a linkage. The device contains a housing which defines a fluid circuit. A slidably mounted pressurizing component communicates with the fluid circuit and is connected to the linkage. The fluid circuit contains a flow restricting device. When the hoist control lever is moved from a first position, wherein the hoist is stationary to a second position, wherein the hoist is moving, the linkage exerts an inward force on the pressurizing component moving the pressurizing component from a neutral to a pressurizing position. Such movement in turn induces a pressure build-up within the fluid circuit. Flow restricting device within the fluid circuit exerts a back pressure on the pressurizing component thereby through the actions of a the pressurizing component and the linkage limits the velocity of the hoist control lever.
