  • Dynamic load compensating system
    Patent number: 4886397
    Abstract: A dynamic load compensation system for supporting a crown block comprises:(a) first structure including the crown block to receive applied loading, and subject to displacement generally in the direction of load exertion,(b) a base frame spaced from that structure, and(c) means including groups of fluid actuator members pivotally connected to the base frame and to that structure for supporting same on the base frame, said members acting to resist such displacement of the structure characterized in that said base frame may move relatively toward and away from the structure while said loading continues to be applied to the structure,(d) the actuators in each group extending in parallel relation.A sheave is typically offset from the crown block to control a line or lines leading to the crown block; and two pivoting links connect the sheave with the base frame and block.This application is a continuation-in-part of my prior application Ser. No. 35,784, filed Apr.

  • Load compensating system
    Patent number: 4883388
    Abstract: A dynamic load compensation system comprises:(a) first structure to receive applied loading, and subject to displacement generally in the direction of load exertion,(b) a base speed from said structure, and(c) means including pairs of generally parallel fluid actuator members pivotally connected to said base and to said structure for supporting said structure on the base, said members acting to resist said displacement of said structure characterized in that said base may move relatively toward and away from said structure while said loading continues to be applied to said structure.

  • Dynamic load compensating system
    Patent number: 4662786
    Abstract: A dynamic load compensation system comprises:(a) a first element to receive predetermined applied loading, and a base spaced longitudinally from that element,(b) structure including articulated members supporting the first element on the base and acting to resist displacement thereof characterized in that the base may move relatively toward and away from the first element while such predetermined loading is applied to the first element,(c) certain of the members extending longitudinally and laterally leftwardly, and others of the members extending longitudinally and laterally rightwardly,(d) first connections including links pivotally interconnecting the certain members, and(e) second connections including links pivotally interconnecting the other members.
