Install overhead line equipment small part steelwork
Overview
This standard identifies the competences you need to install overhead line equipment (OLE) small part steelwork. The term small part steelwork is used to describe items of equipment that are assembled and fitted to the main steel structures such as cantilever assemblies, headspans, cross span wires, registration arms, bridge/tunnel supports and security guards.
The definition of OLE is an arrangement of wires, suspended over the railway line, for supplying electricity to electric trains, together with associated fittings, insulators and other attachments including feeders, autotransformer feeders, overhead line switches, jumpers and return conductors. This equipment together with its structures, foundations, lineside switching stations is described collectively as Overhead Line Equipment.
To prove competence in this standard you shall need to demonstrate your ability to complete the small part steelwork installation, renewal, enhancement or modification activities in accordance with current working instructions. You will be required to determine, from the drawings and specifications, what has to be done and how best it can be achieved safely, within the time frames allowed and appropriate to the environment and site conditions.
Your underpinning knowledge will provide a good understanding of your work, and provide an informed approach to applying steelwork assembly procedures. You will understand the principles and processes associated with the assembly of the small part steelwork and their application. You will know about the ways of handling steelwork, the means of fixing them in position as well as the care and use of the tools and equipment in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring the installed small part steelwork is produced to the required specification. You will understand the safety precautions required when working at height and with steelwork components and their associated tools and equipment. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
Your responsibilities will require you to comply with organisational policy and procedures for the safe installation of the small part steelwork and the associated assembly activities to be undertaken and to report any problems with the component parts, equipment or installation activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with minimum supervision, taking personal responsibility for your own actions and the quality and accuracy of the work that you carry out.
