Description
00 0 1 APPARATUS AND METHOD FOR ERECTING SIGNS SFIELD OF THE INVENTION This invention relates to the erection of signs on tall poles such as road traffic signs and could be applied to any situation where structures are to be raised to heights above the ground.
00 BACKGROUND OF THE INVENTION C 10 At present cranes are usually used to lift road traffic signs into place for fixing to supporting poles. However renting a crane for a job often on a remote location is expensive and disruption to traffic flow can be caused by the operation of the crane on the road near the sign.
Further, manoeuvring large sections of a sign by crane into a precise position for fixing can be difficult especially in windy conditions. It not only requires a skilled crane driver but a fixer located on a ladder or cherry picker who is then vulnerable to injury owing to uncontrolled movement of the sign while fixing.
OBJECT OF THE INVENTION It is therefore an object of the present invention to provide equipment and a method for erecting signs which overcomes the above difficulties or at least provides a useful alternative.
STATEMENT OF THE INVENTION According to the present invention a method of erecting a structure on one or more poles comprises the steps of mounting a winch at the base of each pole, passing the winch rope through a pulley attached to the top of the pole and securing its free end to the structure then winching the structure up the pole and securing it in position on the pole.
00 0 2 Preferably the sign is held against the poles by sliding restraints.
INO
Preferably the pulley is attached to the top of the pole by a hook.
Preferably apparatus for erecting a structure on one or more poles comprises a winch mounted at the base of each pole, a pulley secured at the top of the pole through which the winch rope passes, means for securing the free end of the 00 0rope to the structure and means for restraining the structure against the poles c 10 during erection.
Preferably each winch has a motor and is controlled by a remote controller.
BRIEF DESCIPTION OF THE DRAWINGS The invention is now described by way of example only, with reference to the accompanying drawings in which: Fig 1 is a rear view of a road sign mounted on poles Fig 2 shows winches mounted at the base of the poles Fig 3 shows the winch mounts Fig 4 shows winch ropes and pulleys hooked to the top of the poles Fig 5 shows the hooks and pulleys Fig 6 shows the sign attached to the poles prior to erection and Fig 7 shows the sign erected.
DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows a road traffic sign 1 erected in place at the top of two poles 2.
The method of erection is as follows. Winches 3 are mounted at the base of poles 2 via brackets 4 attached to poles 2 by clips 5 as shown in Figs 2 and 3 00 0 3 SWinch ropes 6 pass through pulleys 7 which are hooked to the top of poles 2 by hooks 8 shown in Figs 4 and 5. Caps (not shown) at the top of poles 2 are C' removed for poles 2 to receive hooks 8.
Lifting lugs 9 at the end of ropes 6 are attached to backing rail 10 on the rear face of sign 1 shown in Figs 6 and 7. Sliding clips 11 loosely hold sign 1 against poles 2 but allow movement of sign 1 up and down poles 2.
00 N 10 With the ratchets of winches 3 engaged to prevent free spooling,sign 1 is winched upwards by turning handles 12 of both winches simultaneously to lift sign 1 to a level position at the top of poles 2. Sliding clips 11 are then replaced by permanent securing clips (not shown) and additional clips are attached to rails 13 and 14 to secure sign 1.
During erection of sign 1 the operators wind winch handles 12 from behind sign 1 and are therefore not directly below sign 1 if the latter falls. Once sign 1 is secured in position, the tension in ropes 6 is released by disengaging the ratchet of winches 3 and lugs 9 are removed form rail 10. Hooks 8 are removed from the top of poles 2 and caps replaced. Winches 3 are then removed from poles 2.
Winches 3 may be automated with motors and remote controls. Accordingly the lifting operation can be performed by one operator remote from poles 2 and the entire erection carried out by one person in safety without a crane and the above mentioned disadvantages.
VARIATIONS
It will be realised that while the foregoing has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall 00 4 Swithin the broad scope and ambit of this invention as is herein set forth. For IND example it will be clear that clips 5 for mounting brackets 4 could be replaced Sby quick release mechanisms. These and other mechanical equivalents fall within the scope of the present invention.
Throughout the description and claims of this specification the word "comprise" and variations of that word such as "comprises" and "comprising", are not 00 0intended to exclude other additives, components, integers or steps.
