ABSTRACT:
An apparatus (10) is used for transporting one or more elongated members (12), such as logs (12) or pipes. The absence of developed roadways into tree cutting sites, for example, requires an apparatus (10) for transporting logs (12) over difficult terrain from the site to other locations. In the apparatus (10) for transporting the elongated member (12), first apparatus (20) controllably engages a first end portion (14) of the elongated member (12) in supporting relationship in response to being urged between the first end portion (14) and the ground (32) in a direction (34) generally longitudinal relative to the elongated member (12). Second apparatus (26) controllably engages a second end portion (16) of the elongated member (12) and maintains the first end portion (14) in supporting relationship with the first apparatus (20). Each of the first and second apparatus (20,26) controllably raises the first and second end portions (14,16) of the elongated member (12), respectively, for transporting the elongated member (12) in a position elevated above the ground (32).
