Abstract

See full text

The present disclosure provides improved linkage assemblies for use with drilling rig and mobile well servicing rig braking systems, and braking systems comprising such improved linkage assemblies. The disclosed improved linkage braking assemblies effectively decouple the emergency brake actuation cylinder shaft and the brake lever upon activation of the emergency brake actuation cylinder, thereby preventing the brake lever from rapid and forceful downward movement, which could injure the operator.
