Abstract

A device (40) for use in lifting and/or lowering objects up or down a pole (4) comprises a frame (42, 48, 50) for mounting the device on a pole and rope guides (60, 66) supported on the frame. The arrangement of the device is such that a rope can pass over the guides and up and down two opposite sides of the pole, while both of these sides are effectively unobstructed by the frame (48) of the device. A clamp device may be attached to the object to be raised (lowered). The clamp grips the object at spaced-apart points and has a central attachment point or guide around which a rope may be passed. Means are provided by which the lifting operation may be performed at a safe distance from the foot of the pole. The device is used for lifting new crossbows onto power transmission or telephone lines. <IMAGE>
