Abstract
There is provided a method of installing spiral hangers about a messenger line installed between first and second utility poles with a cable being lashed to the messenger line with a lashing wire. The method includes attaching a first and second spiral hangers to the messenger line between first and second utility poles with the first spiral hanger disposed about the messenger line and the cable. The method includes removing the lashing wire from being around the messenger line and the cable adjacent the second spiral hanger. The method includes moving the second spiral hanger towards the second utility pole. The method includes attaching a successive spiral hanger to the messenger line between the spiral hangers and repeating the moving of the second spiral hanger and attaching another successive spiral hanger.
Claims20
A crane base support system for use with a parapet wall extending vertically from a floor, the crane base support system comprising:
- a base plate positionable upon the floor;
- a central column extending from the base plate;
- support legs each having a distal end and an attachment end, the attachment end of each of the support legs being rotatably attached to the base plate, the support legs each having an extended position with the support legs extending radially from the base plate and a folded position with support legs extending generally along the central column;
- and
- a parapet wall clamp attached to and extending laterally from the central column, the parapet wall clamp having a jaw with a jaw opening facing generally towards the base plate, the jaw opening being sized and configured to receive and engage the parapet wall.
A crane base support system for use with a parapet wall extending vertically from a floor, the crane base support system comprising:
- a first base plate positionable upon the floor;
- a first central column extending from the first base plate, the first central column including a base end attached to the first base plate and a crane end disposed away from the first base plate;
- a parapet wall clamp attached to and extending laterally from the first central column, the parapet wall clamp having a jaw with a jaw opening facing generally towards the first base plate, the jaw opening being sized and configured to receive and engage the parapet wall;
- a second base plate positionable upon the floor;
- a second central column extending from the second base plate, the second central column including a base end attached to the second base plate and a track end disposed away from the second base plate;
- and
- a main track disposed between the first and second central columns and attached to the crane end of the first central column and attached to the track end of the second central column.
A combined trolley winch system with lift and traverse selection, the trolley winch system comprising:
- an overhead track;
- a trolley engaged with the overhead track, the trolley and the track being cooperatively sized and configured to traverse the trolley along the track;
- a first winch drum having a lift cable cylindrical surface disposed about a reel axis of rotation;
- a lift cable engaged with the winch drum about the lift cable cylindrical surface and engaged with the trolley;
- a second winch drum having a traverse cable cylindrical surface disposed about the reel axis of rotation;
- a traverse cable engaged with the winch drum about the traverse cable cylindrical surface and engaged with the trolley;
- and
- a winding mechanism connected to the first and second drums, the winding mechanism sized and configured to rotate the first drum about the reel axis of rotation for winding the lift cable about the lift cable cylindrical surface independently from rotating the traverse cable cylindrical surface, the winding mechanism sized and configured to rotate the second drum about the reel axis of rotation for winding the traverse cable about the traverse cable cylindrical surface independently from rotating the lift cable cylindrical surface.
