FORESTRY WINCH SYSTEM

GSE TECHNOLOGIES, LLC, H...

1. A winch system coupled to a processor energy source having multiple processor driving rollers, the processor providing
energy to the winch system, the winch system comprising
a body having a front face, a back face, lateral sides, a top, a bottom and an imaginary vertical axis, the body being detachable
from the processor energy source;

multiple drive rollers that are directly driven by the multiple processor driving rollers, the drive rollers being supported
between the top and the bottom of the body so that they are rotatable about axes that are parallel to the vertical axis in
response to the multiple processor driving rollers;

a winch drum supported by the body;
a drum gear that influences the speed and direction of winch drum rotation;
a cable having a proximal end region attached to the winch drum and a distal end region that is detachably attachable to an
object to be retrieved by the winch system, the cable extending outwardly from the front face or back face of the body; and

a reverse gear that is mounted so that it rotates with two of the driven winch drive rollers in a plane that lies perpendicularly
to the vertical axis.

FORESTRY WINCH

GSE TECHNOLOGIES, LLC, H...

1. A winch system coupled to a processor energy source having multiple processor driving rollers, the processor providing energy to the winch system, the winch system comprisinga body having a front face, a back face, lateral side faces, a top, a bottom, an imaginary horizontal axis extending between the lateral side faces, an imaginary vertical axis extending between the top and the bottom, the body being detachably attachable to the processor energy source;
multiple driven rollers that are driven by the processor driving rollers, the driven rollers being supported between the top and the bottom of the body so that they are rotatable about axes that are parallel to the vertical axis in response to the processor driving rollers;
a winch drum supported by the body and extending between the lateral side faces, the winch drum having an axis of rotation that is parallel to the horizontal axis of the body;
a drum gear in communication with the driven rollers and the winch drum that transfers rotational energy about the vertical axis from the processor driving rollers to rotational energy about the axis of rotation of the winch drum and influences the speed and direction of winch drum rotation, wherein the drum gear includes a pair of sprockets and a chain extending around the pair, the chain being adapted to transfer rotary motion from one socket to the other socket in the pair, the sprockets being aligned along an imaginary angled axis so that one is higher than the other; and
a cable that is adapted to wrap around the winch drum, the cable extending substantially horizontally from the front or back faces, the cable having a proximal end region attached to the winch drum and a distal end region that is detachably attachable to an object to be retrieved by the winch system, the distal end region influencing the direction in which the object may fall, the object being located laterally away from the winch system.

ACCESS PLATFORM SYSTEM WITH INTEGRATED FOLDING STEPS

GSE TECHNOLOGIES, LLC, H...

1. An access platform system for enabling access to and egress from ground-based structures, vehicles, and mobile equipment, the system having:a main frame that is attached to or juxtaposed with the ground-based structures, vehicles, or mobile equipment;
a vertical displacement mechanism attached to the main frame, the vertical displacement mechanism having a platform assembly for permitting personnel to stand or ride to raise the personnel to an elevated level or lower the personnel to a lower or ground level, the vertical displacement mechanism also having an electronic controller, including position limit switches, proximity switches, and sensors;
and
a folding steps assembly also attached to the main frame, the folded steps assembly having steps and
an electromechanical means for folding the steps so that the steps are displaceable to, from and between a folded up configuration and a folded down configuration;
the folded up configuration permitting the steps to be folded up to a retracted, out of the way position when the platform assembly is raised or lowered, the folded up configuration blocking access to the ground-based structures, vehicles, and mobile equipment, and allowing the vertical displacement mechanism to freely move upwardly and downwardly without interference by the steps, thereby blocking the folding steps assembly from unauthorized use;
the folded down configuration securing the steps in place, the folded down configuration being a default configuration that permits ingress and egress of persons to or from the ground-based structures, vehicles, and mobile equipment;
the platform assembly being configured to be deployable within an area circumscribed by the folding steps.
