연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A log hauling hand truck that acts as a log transporter and lifter has a generally planar height adjustable platform in combination with a retained and adjustable hook. A hand brake has a releasing actuator and an alternative locking actuator for selective braking by an operator. When the load platform is parallel to the ground, the log hauling hand truck is stabilized by locked wheels, a fixed stand, and handle guards, each which independently contact the ground. Roll-off preventing guards may be provided adjacent to the load surface of the adjustable h...

The log hauling hand truck of claim 1, further comprising a locking brake disabling rotation of at least one wheel within said wheel set. 3. The log hauling hand truck of claim 2, operatively having a stable transfer position facilitating transfer of said logs between said generally planar platform surface and said elevated surface, further comprising: a fixed leg supporting said base upon said ground in said stable transfer position; andat least one handle guard supporting said base upon said ground in said stable transfer position;said locking brake further disabling rotation of said at least one wheel within said wheel set in said stable transfer position. 4. The log hauling hand truck of claim 2, further comprising: a manual, force sensitive and self-releasing brake;said locking brake further comprising an over-center brake lock. 5. The log hauling hand truck of claim 1, further comprising at least one border stop terminating and protruding from said generally planar platform surface adjacent to said at least one handle, said border stop inhibiting said logs from rolling off said generally planar platform surface adjacent to said at least one handle. 6. The log hauling hand truck of claim 1, wherein said generally planar platform surface further comprises an expanded metal platform that operatively bites into a log while simultaneously discharging moisture and debris. 7. A log transporter and lifter facilitating elevating logs from a ground surface and transferring said logs to a surface elevated from said ground surface, comprising: a base;a wheel set supporting said base upon said ground;at least one handle extending longitudinally from said base and defining a longitudinal axis;a generally planar platform surface supported upon said base and terminating said log hauling hand truck distal to said at least one handle; andsaid generally planar platform surface that operatively bites into a log while simultaneously discharging moisture and debris, and that is supported upon said base and terminating said log hauling hand truck distal to said at least one handle; anda means for adjusting a distance perpendicular to said handle longitudinal axis between said generally planar platform surface and said wheel set adapted to operatively align said generally planar platform surface co-planar with said surface elevated from said ground surface when said handle longitudinal axis is generally parallel to said ground surface. 8. The log transporter and lifter of claim 7, further comprising a pivotal, retained and length-adjustable hook operatively capturing said log between said hook and said platform surface. 9. The log transporter and lifter of claim 7, further comprising a locking brake disabling rotation of at least one wheel within said wheel set. 10. The log transporter and lifter of claim 9, further comprising: a fixed leg supporting said base upon said ground and defining a stable transfer position when said handle longitudinal axis is generally parallel to said ground surface; andat least one handle guard supporting said base upon said ground in said stable transfer position;said locking brake further disabling rotation of said at least one wheel within said wheel set in said stable transfer position. 11. The log transporter and lifter of claim 9, further comprising: a manual, force sensitive and self-releasing brake;said locking brake further comprising an over-center brake lock. 12. The log transporter and lifter of claim 7, further comprising at least one border stop terminating and protruding from said generally planar platform surface adjacent to said at least one handle, said border stop inhibiting said logs from rolling off said generally planar platform surface adjacent to said at least one handle. 13. The log transporter and lifter of claim 7, wherein said generally planar platform surface further comprises an expanded metal platform that operatively bites into a log while simultaneously discharging moisture and debris. 14. A log transporter, lifter and transfer apparatus facilitating grasping logs from a ground surface, elevating said logs, and from a stable transfer position transferring said logs to a surface elevated from said ground surface, and similarly receiving logs from said elevated surface, lowering said logs to said ground surface, and releasing said logs to said ground surface, comprising: a base;a fixed leg supporting said base upon said ground in said stable transfer position;a wheel set supporting said base upon said ground;a locking over-center brake disabling rotation of at least one wheel within said wheel set in said stable transfer position;a manual, force sensitive and self-releasing brake;at least one handle extending from said base;at least one handle guard terminating said handle distal to said base and at least in part supporting said base upon said ground in said stable transfer position;a generally planar expanded metal platform surface that operatively bites into a log while simultaneously discharging moisture and debris, and that is supported upon said base and terminating said log hauling hand truck distal to said at least one handle;at least one border stop terminating and protruding from said generally planar platform surface adjacent to said at least one handle, said border stop inhibiting said logs from rolling off said generally planar platform surface adjacent to said at least one handle;a pivotal, retained and length-adjustable hook operatively capturing said log between said hook and said platform surface; anda means for adjusting a distance between said generally planar platform surface and said ground surface in said stable transfer position to operatively align said generally planar platform surface co-planar with said surface elevated from said ground surface. 15.
