Abstract
A tree transporting vehicle with a base subassembly for propelling the vehicle, a catch bed assembly for receiving felled trees to transport them with an integral unloading mechanism, and a positioning linkage operatively connecting the base subassembly and catch bed assembly for selectively positioning the catch bed assembly with respect to the base subassembly. The operation of the vehicle is controlled from a side mounted cab where the operator is in a standing-sitting position.
Claims20
A tree transporting vehicle comprising:
- a base subassembly having a support frame and ground engaging means for moving said base subassembly;
- a catch bed assembly for receiving the trees to be transported and supporting the trees therein above said base subassembly, said catch bed assembly including:
- a carriage frame;
- a catch bed movably carried by said carriage frame and defining a tree receiving chamber therein with open front and rear ends and an open top;
- a heel plate assembly movably carried by said carriage frame and extending into said tree receiving chamber;
- tie means interconnecting said bed and said heel plate assembly so that said heel plate assembly is moved with said bed as said bed is moved forwardly in said carriage frame but said bed moves rearwardly in said carriage frame independently of said heel plate assembly;
- and,
- interlock means operatively connecting said carriage frame, said bed and said heel plate assembly to selectively lock said heel plate assembly in its forwardmost position and to release said heel plate assembly from its locked position when said bed is in its rearmost retracted position for said heel plate assembly to move to its rearmost retracted position independently of said bed;
- and,
- a positioning linkage operatively connecting said catch bed assembly with said support frame, said positioning linkage movably positioning said catch bed assembly with respect to said base subassembly to receive the trees and to discharge the trees therefrom.

A tree transporting vehicle comprising:
- a base subassembly having a support frame and ground engaging means for moving said base subassembly;
- a catch bed assembly for receiving the trees to be transported and supporting the trees therein above said base subassembly, said catch bed assembly including:
- a carriage frame;
- a slide rail assembly movably mounted on said carriage frame;
- a catch bed movably carried by said slide rail assembly for movement relative to said slide rail assembly and said carriage frame, said catch bed defining a tree receiving chamber therein with open front and rear ends and an open top;
- a heel plate assembly movably carried by said slide rail assembly and extending into said tree receiving chamber for movement relative to said carriage frame, said slide rail assembly and said bed;
- and,
- tie means interconnecting said bed and said heel plate assembly so that said heel plate assembly is moved with said bed as said bed is moved forwardly in said carriage frame but said bed moves rearwardly in said carriage frame independently of said heel plate assembly;
- and,
- a positioning linkage operatively connecting said catch bed assembly with said support frame, said positioning linkage movably positioning said catch bed assembly with respect to said base subassembly to receive the trees and to discharge the trees therefrom.

A tree transporting vehicle comprising:
- a self-propelled base subassembly having a support frame with a longitudinal axis and a forward end and ground engaging means for supporting and moving said base subassembly;
- a carriage frame assembly having a longitudinal axis;
- a positioning linkage mounting said carriage frame assembly on said base subassembly, said positioning linkage selectively movably positioning said carriage frame assembly with respect to said base subassembly while maintaining the longitudinal axis of said carriage frame assembly generally vertically aligned with the longitudinal axis of said base subassembly to independently elevate and tilt said carriage frame with respect to said base subassembly;
- a catch bed having a front end and a rear end movably carried by said carriage frame assembly for selective movement of said catch bed forwardly and rearwardly with respect to said carriage frame generally along the longitudinal axis of said carriage frame assembly between an extended forward position and a retracted rear position, said catch bed defining a tree receiving chamber therein having an open front end;
- a heel plate assembly movably positioned with respect to said catch bed and said carriage frame for movement generally along the longitudinal axis of said carriage frame assembly between a first retracted position and a second extended position with respect to said carriage frame assembly, and between a third rear position and a fourth front position with respect to said catch bed, said heel plate assembly including a heel plate extending into said tree receiving chamber;
- and
- ejection means for moving said heel plate assembly from its first retracted position to its second extended position with respect to said carriage frame assembly while simultaneously moving said catch bed between its retracted rear position to its extended forward position, and for moving said catch bed from its extended forward position to its retracted rear position while maintaining said heel plate assembly in its second extended position with respect to said carriage frame and while moving said heel plate assembly with respect to said catch bed between its retracted rear position and its extended forward position.
