  Part I 1.1 - Introduction This manual has compiled to assist site management with the following:

Assembly, erection, operation and periodic maintenance of lighting masts with winch operated raising and lowering equipment.

•

•

Before starting operation, users are recommended to carefully read the instruction.

•

Lighting masts floodlighting manufactured by HAPULICO is made based on the structure of steel section with length suitable for transport and installation.

•

Sections of the Mast body and Utilities are manufactured by modern production line with advanced technology.

•

Our engineers had made necessary calculation to gain the comprehensive capacity on mast structure. A special computer program was used to achieve figures which match the height, load and wind velocity of polygon section mast.

•

Strictly following content of working security is essential during the period of installation, operation and maintenance.

•

Save time, make it easy to deal with the mast if instruction is closely followed.

•

The constant development and progress in design and manufacture of the company may make some actual parts of the mast different from the one in supplied material. The company holds the rights to modify our production without prior notice.

1.2 - Safety warning Safe working practices in assembly, erection and operation of the equipment should be observed at all times. It is essential that the following procedures are followed when operating the equipment. 1. Mechanical and electricity works must be controlled by qualified qualified and authorized person only. 2. Unauthorized and observation people must keep a safe distance from the mast. 3. Durin During g the work, do not stand right under: -

Column sections are co-axially packed inside each other for ease of handing in transport transport The fixed bracket assembly and accessories are packet in separate containers. The winch is supplied mounted on its mounting bracket bracket ready for bolting into the mast. The eq equipmen uipmentt required required at site will be : a. A mobile crane of sufficient capacity and lift height. b. Suit Suitable able slings. slings. c. A quantity of wedges and timber for packing, to suit the number of column section d. Two pull lift devices with a minimum capacity of 4 tonnes tonnes e. A crowbar, crowbar, a sledge hammer... hammer... f. A quantity of rubber based grey paint or linseed oil to suit the number of joints. g. A crew of 4 men are normally required to to carry out the assembly and erection, in addition to the crane crew. 5. Unload the column sections sections onto the packing on the ground in order of assembly and in in line so that the center of gravity will be adjaccent to the column foundation when assembled, making due allowance for the joint overlap. This will minimise crane handling when erecting the column (Figure 2.1).

ASSEMBLY ASSEMBLY OF COLUMN COLUMN SECTIONS SECTIONS 1. Arrange the base section onto the packing with the access opening on the top top and levelled so that the axis of the column section will be horizontal. The height of the packing must be 6

 

compatible with the base plate and the fixed bracket dimentions so that both will be clear of  the ground when assembled. 2. Make sure that the base plate is is wedge to to prevent rotation. rotation. 3. Check that the packing packing under the arranged sections is a minimum of 300mm clear of the end of the slip joint length ( L ) (Figure 2.2) to allow for column during assembly.

The external suface suface of the the lower column column section is coated for approximatetely 75% of  the slip joint length from the end of the section.The minimum length of the slip joint is marked on the male section of the column joint, with red coloured paint. b. The internal surface of the upper column section is coated for approximately 75% of the slip joint length leaving the first 25 % of o f slip joint length clear.

Do not use oil or grease grease for assembly assembly lubrication as this may lead lead to a detrimental detrimental appearance if runs or drips are formed. 7. Sling the section section for assembly assembly at its its centre of gravity and engage the the sections, making sure that the centre line of the column is correctly aligned in the horizontal and vertical planes. 8. While installing installing the pull winchs winchs into 2 sides of the the column under the close close supervision pull pull winch will move unanimously to ensure column sections to be fitted synchronously according to the column axis.(figure 2.4)

9. During operation perform perform step. 8 the external external surface of the slip slip joint joint can be hammered hammered using a wooden block and a sledge hammer, to assist in achieving a good joint. Do not hammer directly on the galvanised surface. The length of the slip joint “L” according to design. 10. Misalignment of the sections for any reason may lead to jamming, which will prevent good telescoping of the joint any may be difficult to rectify. 11. Compare of theoretical slip joint length with the actual slip joint length, and if necessary continue to apply pressure as describel in 9 above until at least the minimum nominated dimension is obtained. 12. Continue assembly process of column step. 3. Always check straight level of the column sections. 13. When the final section of the column is in plate, the pack packing ing must be arrange so that there is at least 1300mm to enable fitting of the fixed bracket at a later stage.

At the lifting point a suiteble sling is applied from which two “Pull-lift” or similar divices, one each side of the column, are arranged with the lower end anchored at the base plate. These “Pull-Lift” devices are tensioned to avoid a possible seperation of slip joint, and to prevent the sling from slipping up the column (Figure 5.2) 4. Before lifting lifting the column, mark the the base plate and foundation foundation to ensure that the fixed bracket assembly and lighting array are correctly aligned. 5. If necessary, rotate the column on the packing prior to to lifting to facilitate the alignment.
