Description Rocla's reinforced, hollow, spun concrete poles are the "benchmark" product for long life, zero maintenance, streetlighting poles. The poles are available in a wide range of lengths, load capabilities and fitting requirements. The elegant appearance of the pole with its" smooth light grey finish and continuous taper, makes it aesthetically pleasing. The streetlighting poles are manufactured from high quality concrete, and are available in standard lengths from 4,5m to 13,0m. Due to the loading nature of the application, the standard streetlight pole is manufactured to the lower strength range specification in SABS 470 although other lengths and strengths can be designed and manufactured to suit customer requirements.

The standard strength classes for these poles are 25L, 50L, 75L and 100L. Special intermediate strengths or heavier loading requirements can be designed and manufactured. These are subject to various material constraints, but will be evaluated by our engineers on an ad hoc basis. The concrete mix used during the manufacture of these poles can be modified to suit aggressive environments or soil conditions. Please use the contact us facility for further inquiries into these options. The earthing of the system can be accommodated through the reinforcing of the pole. This eliminates the need for additional earthing requirements. A Samite rail is cast into the pole as standard, and the circuit breakers can be attached thereto.

Accessories Access opening An access opening is cast above ground level to facilitate inspection and maintenance of the system. Galvanised Steel Door A galvanised steel door is used to close the opening and prevent vandalism and theft. The rubber gasket or the door shields the circuit breakers from the elements and so doing prolongs the use of the installation. Cable entry A cable entry is supplied below ground level for the purpose of running the cables inside the centre of the pole. Samite Rail A samite rail is cast inside the access opening for the attachment of the circuit breakers. Spigot A stainless steel spigot can be cast into the pole for the attachment of post top lights.

Areas of Use Precast concrete poles are widely used in streetlighting applications. Areas with aggressive environments are especially suited for this product. The poles can also be used in security applications where lights and cameras have been mounted. They are ideal in applications where maintenance-free, high quality solutions are required.

Handling and Installation When handling any concrete products, it is important to remember that, as concrete is a heavy and somewhat brittle material, bumps or shock loads of any description are liable to damage the product. This applies particularly to sharp edges. All poles are transported in a horizontal position, and should be left in this position until lifting into the foundation. When off-loading, two 150mm sling must be used and spread apart in order to distribute the weight of the pole. The pole must be placed on level ground, and not be allowed to bend. The excavation of the foundation must be to the engineer's specification. All poles carry a mark that indicated 1,5m above ground level. This assists with the inspection of the excavation depths. In wider foundations, the foundation can be pre-prepared, by casting a sleeve in the center of the foundation by using manhole sections. This limits crane time when installing the pole, as the volume of material to be backfilled will be greatly reduced. If the poles are to carry any attachment steelwork such as clamps, then we suggest that these be attached prior to the lifting of the pole. The poles should be lifted into a vertical position by attaching the sling approximately one third of the length from the tip. A system to release the sling once the pole is planted must be kept in mind. The pole is lifted by using a crane, and lowered into the hole. The Pole must be leveled from two sides at 90 degrees to ensure that the pole is upright. If required, earthing of the structure must be done at this point. The backfilling of the void between the pole and the foundation or surrounding soil must be done using a 1:8 cement:sand mixture, or other material as specified by the engineer. Compaction of the backfill material must be done in layers of 150mm or as specified by the engineer. Once the foundation is compacted a half to two thirds complete, then the crane can be released and move to the next point or installation. For more information on pole installation, please use the contact us facility, as our staff can be of assistance on site with the installation activities.
