A dragline comprises a main chassis, a mechanism for moving the main chassis over the ground, a boom mounted on the main chassis, a sheave rotatably mounted on the boom, a dragline bucket, a hoist rope reeved over the sheave and having an end connected to the bucket to raise and lower the bucket, a
A dragline comprises a main chassis, a mechanism for moving the main chassis over the ground, a boom mounted on the main chassis, a sheave rotatably mounted on the boom, a dragline bucket, a hoist rope reeved over the sheave and having an end connected to the bucket to raise and lower the bucket, a drag rope connected to the bucket to pull the bucket toward the main chassis and to allow the bucket to move away from the main chassis, and an operator station on the main chassis, the operator station including a control lever apparatus for permitting an operator to control one of the mechanism, the hoist rope and the drag rope. The control lever apparatus includes a housing having therein a control mechanism for operating one of the mechanism, the hoist rope and the drag rope, a control lever mounted on the housing and operably connected to the control mechanism, the control lever being movable in a single plane relative to the housing, a shroud generally exterior of the housing, the shroud providing a rest for supporting an operator\s hand gripping the control lever, and a locking mechanism mounted on the shroud and including a locking member which is movable relative to the housing for selectively capturing the control lever and thereby preventing movement of the control lever relative to the housing.
