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.

초록

An adjustable lift truck having a frame with a first end and an opposing second end. The frame defines a longitudinal axis that extends from the first end to the second end. A pair of transport wheels are rotatably mounted to the frame proximate the first end. A pair of laterally spaced-apart outriggers extend generally perpendicularly to the longitudinal axis of the frame. Each outrigger is located proximate the first end of the frame, and includes a first end pivotally attached to the frame and an opposing free second end.

1. An adjustable lift truck comprising: a frame having a first end and an opposing second end, the frame defining a longitudinal axis extending from the first end to the second end, and comprising two laterally spaced-apart beams, each spaced-apart beam having a lower end portion;a pair of laterally spaced-apart transport wheels rotatably mounted to the frame proximate the first end thereof; anda pair of laterally spaced-apart outriggers, extending generally perpendicular to the longitudinal axis of the frame, each outrigger being located proximate the first end of the frame, and each outrigger including a first end, pivotally attached to and angularly pivotable with respect to each lower end portion, and an opposing free second end, including a support wheel on a lower surface thereof. 2. The adjustable lift truck according to claim 1, wherein the pair of outriggers are pivotable between a first position defining a generally ninety degree angle therebetween, a second position defining an angle of less than ninety degrees, and a third position such that the outriggers extend generally parallel to each other. 3. The adjustable lift truck according to claim 2, further comprising: a base fixedly attached to the first end of the frame, the transport wheels being rotatably attached to the base;and an adjustment lever pivotally supported by the base and operatively connected to each outrigger,the lever being pivotable to pivot the outriggers between the first, second and third positions, respectively. 4. The adjustable lift truck according to claim 3, wherein the base connects the two-laterally spaced-apart beams at the first end of the frame and a top brace connects the two laterally spaced-apart beams at the second end of the frame. 5. The adjustable lift truck according to claim 4, wherein the frame includes two laterally spaced-apart support shafts, a first end of each support shaft being fixedly attached to a portion of the base and a second end of each support shaft being fixedly attached to a portion of the top brace, and wherein each support shaft is at least slightly non-linear such that each support shaft extends outwardly from the beams and provides structural support to the beams. 6. The adjustable lift truck according to claim 5, wherein at least one handle extends from at least one of the two-laterally spaced-apart beams to at least one of the support shafts to provide structural support to the frame and a point of contact for a user to grab. 7. The adjustable lift truck according to claim 1, further comprising: a carriage movably mounted to the frame along the longitudinal axis thereof; anda winch fixedly attached to the frame and operatively connected to the carriage, wherein operation of the winch moves the carriage with respect to the frame. 8. The adjustable lift truck according to claim 7, further comprising: a carriage lock having a rod attached to a pivotable carriage lever, wherein pivoting the carriage lever moves the rod into and out of engagement with at least a portion of the frame to either lock the carriage in a discrete position or allow movement of the carriage with respect to the frame. 9. The adjustable lift truck according to claim 1, wherein at least two separate lifting attachments are each removably attachable to the carriage for raising or lowering two or more different objects, wherein the lifting attachments are selected from the group consisting of a fork attachment, a platform attachment and a drum lifting attachment. 10. The adjustable lift truck according to claim 1, further comprising: a handle extending outwardly from the frame; two laterally spaced-apart support shafts; and a pair of loading wheels rotatably attached to a portion of the support shafts. 11. An adjustable lift truck comprising: a frame having a first end and an opposing second end, the frame defining a longitudinal axis extending from the first end to the second end, and comprising two laterally spaced-apart beams, each spaced-apart beam having a lower end portion;a pair of laterally spaced-apart outriggers extending generally perpendicular to the longitudinal axis of the frame, each outrigger being located proximate the first end of the frame, and each outrigger including a first end, pivotally attached to and angularly pivotable with respect to each lower end portion;a pair of laterally spaced-apart transport wheels rotatably mounted to the frame proximate the first end thereof;a carriage movably mounted to the frame along the longitudinal axis thereof; anda winch fixedly attached to the frame and operatively connected to the carriage, wherein operation of the winch moves the carriage with respect to the frame. 12. The adjustable lift truck according to claim 11, further comprising: a lifting attachment removably attachable to the carriage and directly engageable with an object to be lifted. 13. The adjustable lift truck according to claim 11, wherein a cable attaches the carriage directly to the winch. 14. The adjustable lift truck according to claim 13, further comprising: a carriage lock having a rod attached to a pivotable carriage lever, wherein pivoting the carriage lever moves the rod into and out of engagement with at least a portion of the frame to either lock the carriage in a discrete position or allow movement of the carriage with respect to the frame. 15. An adjustable lift truck comprising: a frame having a first end and an opposing second end, the frame defining a longitudinal axis extending from the first end to the second end, and comprising two laterally spaced-apart beams, each spaced-apart beam having a lower end portion;a base fixedly attached to the frame proximate the first end thereof;a pair of laterally spaced-apart transport wheels rotatably mounted to the base;a pair of laterally spaced-apart outriggers extending generally perpendicular to the longitudinal axis of the frame, each outrigger being located proximate the first end of the frame, each outrigger including a first end pivotally attached to-each lower end portion, and an opposing free second end, the free second end of each outrigger including a support wheel on a lower surface thereof, the pair of outriggers being angularly pivotable to at least three positions;an adjustment lever pivotally supported by the base and operatively connected to each outrigger, the adjustment lever being pivotable to pivot the outriggers between the at least three positions, respectively;a carriage movably mounted to the frame along the longitudinal axis thereof; anda winch fixedly attached to the frame and operatively connected to the carriage via a cable,wherein operation of the winch moves the carriage with respect to the frame.
