Abstract

A transportation system for transporting a load into and out of a serviced area. The transportation system comprises near and far support lines and a cross support line suspended from the near and far support lines. A trolley assembly traverses the cross support line, and the trolley assembly is adapted to carry the load from the area to harvested. A transfer track may be used to allow the trolley to traverse the near and/or far support lines.

Claims1

Dependent claims

A transportation system for transporting a load to and from a served area, the system comprising:

a) a cross support line having first and second ends, the cross support line being suspended above the ground;
b) a first support line which intersects the cross support line;
c) a trolley assembly suspended from the cross support line, the trolley assembly comprising:
i) a first wheel;
ii) a second wheel;
iii) a motor for rotating at least one of the first wheel and the second wheel to cause the trolley assembly to move between the first end of the cross support line and the second end of the cross support line;
iv) a load bearing assembly for engaging the load so that the load can be transported along the cross support line, the load bearing assembly being a hoist assembly for raising and lowering raw timber;
v) a structural member from which the load bearing assembly is suspended and to which the first and second wheels are rotatably attached;
vi) an equipment platform mounted to the structural member, where the equipment platform supports a generator for providing energy to the motor;
wherein the cross support line from which the trolley assembly is suspended extends under the first wheel and over the second wheel and the second wheel is attached to the structural member between the first wheel and the load bearing assembly;
d) a transfer assembly adapted to engage the cross support line and the first support line to allow the trolley assembly to move between the cross support line and the first support line and along the first support line, the transfer assembly comprising a plurality of segments pivotably joined together such that the transfer assembly accommodates a range of angles between the cross support line and the first support line;
and
e) a post assembly comprising:
i) a fixed support member configured to support at least a portion of the first support line;
and
ii) a movable support member configured to support at least a portion of the cross support line, where the movable support member is movable to raise and lower the cross support line at the post assembly.
