ABSTRACT:
A lift for opening and closing truck hoods. The lift has a primary actuator with a pair of upper and lower thrust rods oppositely reciprocal within a housing driven by a reversible motor and chain. The rods are connected to the firewall and hood at pivotal connections. The connection on the hood may be slidable to provide clearance of obstacles such as engine compartment components. In an alternate embodiment, the upper thrust rod is pivotally connected to the interior of the hood and the distal end of the lower rod is pivotally attached to a second actuator which, when operated, will move the pivot point forwardly to achieve full or additional opening clearance of the hood. The actuator has a wide variety of applications where extended “reach” is desired.
