Abstract:
A grapple apparatus may comprise at least one grapple arm movable between an open and a closed position, and having a proximal arm portion and a distal arm portion. The apparatus may include a primary actuator having extended and retracted conditions to move the proximal arm portion, and a secondary actuator having extended and retracted conditions to move the distal arm portion. The primary actuator may be configured such that an initial rate of movement of the primary actuator from the extended condition toward the retracted condition is slower than an initial rate of movement of the secondary actuator from the extended condition toward the retracted condition to produce substantially complete movement of the distal arm portion of the at least one grapple arm toward the open position before movement of the proximal arm portion toward the open position is initiated.
