Abstract
A system for the raising and lowering of telescopic masts which operates in one of two general ways, the first way of which includes an attached jack which pulls rather than pushes to effect erection of the mast and the second way where an external turning motion is translated into an internal turning motion which causes the telescopic mast sections to be pushed from the bottom to effect erection of the mast.
Claims7
A self-erecting telescopic mast comprising a plurality of hollow concentric mast sections including a bottom/outer mast section and further sections having an increasingly smaller diameter with respect to the diameter of the bottom/outer mast section;
- a mechanical erecting means for erecting each mast section relative to a next outer section, said erecting means comprising an elongated element mounted relative to said bottom/outermost mast section exterior to the mast sections, and a jacking means for movement relative to said elongated element, said jacking means being adapted to travel upwardly along the length of said elongated element and including a second elongated element having clamping means at an upper end thereof for pulling each mast section upwardly from its next surrounding mast section by clamping the mast section at a top end thereof;
- and
- locking means for fixing each mast section relative to its next adjacent section in erected position.
A self-erecting telescopic mast comprising a plurality of hollow concentric mast sections including a bottom/outer mast section and further sections having an increasingly smaller diameter with respect to the diameter of the bottom/outer mast section;
- a mechanical erecting means for erecting each mast section relative to a next outer section, said erecting means comprising an elongated element mounted relative to said bottom/outermost mast section internally to the mast sections, and a jacking means for movement relative to said elongated element, said jacking means being adapted to travel upwardly along the length of said elongated element and comprising a plurality of disks corresponding in diameter to the diameters of the mast sections for pushing each mast section upwardly from its next surrounding mast section by engaging a bottom inside portion of each section;
- and
- locking means for fixing each mast section relative to its next adjacent section in erected position.
A self-erecting telescopic mast comprising a plurality of hollow concentric mast sections including a bottom/outer mast section and further sections having an increasingly smaller diameter with respect to the diameter of the bottom/outer mast section;
- a mechanical erecting means for erecting each mast section relative to a next outer section, said erecting means comprising an elongated element mounted relative to said bottom/outermost mast section internally to the mast sections, and a jacking means for movement relative to said elongated element, said jacking means being adapted to travel upwardly along the length of said elongated element and comprising a plurality of lifting arms adapted to be expanded radially outwardly from said elongated element so as to be inclined with respect to said elongated element for pushing each mast section upwardly from its next surrounding mast section by engaging a bottom portion of each section;
- and
- locking means for fixing each mast section relative to its next adjacent section in erected position.
