Abstract

The raising of a transmission pole or lighting mast (10) from a horizontal position to an erect position consists in pivotally securing the base (14) to a stub root (20) by means of a pivot pine (16). A strut (22) is fixed to the base (14) and a pull rope (26) is secured to an eye (28) provided on the mast (10) and passes over a pulley (24) at the top of the strut (22). The mast is then raised to the vertical position, by winching the pull rope, the base (14) is clamped to the stub root (20) and the strut (22), pull rope (26) and pivot pin (16) removed for erection of the next pole or mast. <IMAGE>

Description

SPECIFICATION A method of raising a transmission pole or lighting mast The present invention relates to a method of raising a transmission pole or lighting mast from a substantially horizontal position to an erect position.
Previous known methods usually require the employment of expensive equipment such as cranes or heavy lifting tackle to erect transmission poles or lighting masts.
It is an object of the invention to be able to erect a large number of such poles or masts in a relatively short time using only a minimum amount of exterior equipment which has to be brought to the site.
According to the present invention there is provided a method of raising a transmission pole or lighting mast from a substantially horizontal position to an erect position including the steps of: (a) pivotally securing the base of the pole or mast to a stub root mounted in the ground; (b) fixing a strut either to the base of the pole or mast so that said strut stands substantially vertically when the pole or mast is horizontal; or into or on the ground beside the strut root remote from the point at which the base of the pole or mast is pivotally connected to the stub root; (c) securing a pull rope from a point on the pole or mast whose distance from the base thereof is equal to or greater than the length of the strut; (d) passing the pull rope over pulley means secured to the top of the strut; (e) pulling the free end of the pull rope in orderto erect the mast; (f) clamping the base of the pole or mast to the stub root when erect; and (g) removing the pull rope strut and pivot.
In an alternative form of the method, in step (c) a tie rope is secured from a point on the pole or mast whose distance from the base thereof is substantially equal to the length of the strut, to a point at the upper end of the strut; in step (d) a pull rope is secured to the top of the strut; and in step (g) the tie rope is additionally removed.
The present invention will now be described in greater detail by way of example with reference to the accompanying drawings wherein: Figure 7A to ICshow three stages in one preferred method of erecting a folded sheet steei transmission pole; Figures 2A to 2C show three stages in a second method of erecting a transmission pole; and Figures 3A to 3C show three stages in a third method of erecting a transmission pole.
Referringfirstto Figures 1Ato 1C,thetransmission pole 10 to be erected is laid in a horizontal position with its upper end resting on a support 12.
The base 14 of the pole 10 is pivotally connected temporarily by means of a hinge pin 16 to a stub root 18 which is buried in the ground except for its head 20. One end of a strut 22 is connected to the base 14 of the pole 10. The other end of the strut 22 carries a pulley 24. A pull rope 26 is threaded over the top of the pulley 24 and is tied or secured to an eye-hole 28 on the side of the mast 10. The strut 22 is restrained from moving in the direction of pull by means of a stay 33 connected to the upper part of the strut 22 and the eye-hole 28 on the mast.
To raise the mast from the position shown in Figure 1A, the free end of the pull rope 28 is pulled by a winch or other suitable apparatus until the mast 10 has reached the erect position shown in Figure 1 C. At the intermediate position shown in Figure 1 B, the pull rope 26 comes free of the pulley 24. A restraining stay rope 30 is provided for holding the mast in an upright position to enable bolts to secure the base 14 of the mast 10 to the head 20 of the stub root 18.
Once the mast is erect and bolted, the restraining stay rope 30, the strut 22, the pull rope 24, the stay 33 and the hinge pin 16 are all removed and ready for use to erect another transmission pole or lighting mast.
In the second method of erecting a transmission pole or lighting mast shown in Figures 2A to 2C, the strut 22 instead of being connected to the base 14 of the mast 10 is free-standing on the ground at a point near the base of the stub root 18 remote from the hinge pin 16. The strut is held vertical by means of stay ropes 32. As shown in Figure 2A, three stay ropes 32 are shown, whose anchorage points are approximately equi-spaced by 120 around the circumference of the circle with the bottom of the strut 22 as centre.
The method of raising is identical with that described in connection with Figures 1Ato 1C except that at some position between the views shown in Figures 2B and 2C, the pull rope 26 comes clear of the pulley 24 at the top of the strut 22. It will be appreciated that it is preferable that when the mast is in the erect position, the fixing eye 28 should be above the top of the pulley 24 in order that the pull rope can clear the top of the strut.
Again, having erected the mast and clamped or bolted the base 14 of the mast 10 to the head 20 of the stub root 18, the stay rope 30, the pull rope 26, the strut 22 together with its supporting stay ropes 32, and the hinge pin 16 are removed and reused for the erection of the next transmission pole or lighting mast.
In the third method of erecting a transmission pole or lighting mast shown in Figures 3A to 3C, the pulley 24 is omitted and the pull rope 26 is secured to the top of the strut 22. The stay 33 is replaced by a single tie rope 34 connected between the top of the strut 22 and the eye-hole 28 on the mast. This method is used in the case of embodiment shown in Figures 1A to 1C where the strut is connected to the base 14 of the pole or mast 10. When the pole or mast has been erected, the tie rope 34 is removed along with the strut 22, pull rope 26 and the hinge pin 16.
With the three above described methods of erection, it will be appreciated that a large number of transmission poles or lighting masts can be quickly and readily erected on site using a minimum amount of heavy equipment.
