ABSTRACT:
A transport device for moving a load, e.g. tree trunks from one point to another, and comprising a pull band (3) extending between these two points, one end of the band being connected to a winch (2) and the other to a support (9) by a resilient member (4). The winch gives the band a reciprocating motion in its longitudinal direction which moves one or more holding members (5) releasably attached to the band (3). The loads are connected to the holding members. The holding member (5) comprises a casing (12) slotted in its longitudinal direction, the width of the slot (18) exceeding the thickness of the band and said casing being provided with means (20) for preventing an unintentional passage of the band through the slot. The holding member (5) and/or the band (3) is provided with locking members (16) arranged to lock the holding member relative to the band in one of the directions of motion and to release the band in the opposite direction of motion. A releasing member ( 23) is arranged at an optional place along the band, said releasing member against the action of said means (20) displaces the band out of the holding member (5) through the slot (18).
