Equipment/​Electrical engineering.

Acting innovatively.

Together with our colleagues in the parent company and the consolidated technical expertise in contact line/​electrical engineering, we develop and supply the optimum energy structure for the entire railway network, tramways, and urban and industrial railways. We build and renew contact line systems, signalling and safety engineering technology, telecommunications, electrical power systems and conductor rail systems. Our civil engineering and cable-laying expertise completes our portfolio in this trade. We also carry out the design and construction planning for contact line projects.

Planning and design

SPITZKE’s own design consultancy covers all phases of electrical engineering project planning: It performs independent preliminary, detailed and final design and construction planning tasks for contact line projects and electrical power systems. SRS can call upon this service at any time.

  • Planning of overhead line systems
  • Planning & design of 50 Hz projects
  • Structural calculations
  • Soil investigations
  • Development of special solutions

Foundations

Deep foundations, foundations and mast erection work – Using special technology, our experts in the Group erect the masts and signal cantilevers, build signal bridge foundations, build the foundations and supporting columns for highly impacted noise control walls and temporary bridges for railways, and contact line masts for power supply companies. We do this using the following methods: Pile-driving, drilling, down-the-hole drilling (DTH – drilling from starter pits), rotary drilling and in-situ concrete. .

  • Foundations for:
    Contact line masts for mainline and regional railways
    Signal brackets and gantries
    Overhead line masts
    Wind power systems
  • Erection of catenary supports for mainline and local transport railways
  • Piling sheet piling and retaining walls
