<p>A transport device for moving a load, e.g. tree trunks from one point to another, and comprising a pull band extending between these two points, one end of the band being connected to a winch and the other to a support by way of a spring member. The winch gives the band a reciprocating motion in its longitudinal direction and moves the load by means of one or more holding members attached to the band. The loads are connected to the holding members. The holding member comprises a casing slotted in its longitudinal direction, the width of the slot exceeding the thickness of the band and the casing being provided with an arrangement for preventing an unintentional passage of the band through the slot. The holding member and/or the band is provided with locking members 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 is arranged at an optional place along the band. The releasing member displaces the band out of the holding member through the slot against the action of the preventing arrangement.</p> |
