Abstract: A climbing tree stand. In one embodiment, the tree stand includes a first platform and a second platform. The first and second platforms include a base frame, a first arm and a second arm, a support arm, first and second illumination assemblies, and a blade attached to an upper bracket of the base frame. The first and second arms are pivotally attached to the base frame and are releasably engageable with the support arm. The support arm includes curved portions at opposed distal ends thereof. The first illumination assembly is attached to a distal end of the first arm and the second illumination assembly is attached to a distal end of the second arm of each platform. The second platform includes a foot support lifting bracket attached to its base frame. The foot support lifting bracket is comprised of a rigid, non-flexible structure.

Abstract: A boom lock assembly is disclosed. The boom lock assembly locks a boom in a boom saddle and includes a lock mounting frame, a boom lock, and a boom lock actuator. The lock mounting frame is attached to the boom saddle frame. The lock mounting frame includes an actuator support member and a lock support member. The boom lock is slidably mounted on the lock support member and is moveable between a first extended position and a second retracted position. When the boom lock is in the first extended position, the boom lock captures the boom between the boom saddle and the boom lock. When the boom lock is in the second position, the boom lock permits movement of the boom out of the saddle. The boom lock actuator is mounted to the actuator support member at a first end and the boom lock at a second end. The boom lock actuator moves the boom lock to its first and second positions.
