Infrastructure Access Solutions for Tunnel, Bridge and Nuclear Projects

Infrastructure Access Solutions is part of Alimak Group. We design and manufacture access, lifting and handling equipment for permanent and temporary use. Our engineers and technicians carry equipment from early design through manufacturing and testing.

Access, Lifting and Handling Under One Engineering Scope

Most infrastructure sites need all three disciplines at once. We treat them as a single scope, so interfaces between platforms, hoists, and conveying equipment are resolved on the drawing board.

Access work means reaching the structure and staying there safely. Our range includes:

  • Access platforms and installation platforms
  • Pillar platforms and welding platforms
  • Suspended cradles and post-tension access systems
  • Rack and pinion elevators for shafts and pillars

Lifting scopes on infrastructure projects involve awkward loads and restricted headroom. Often there is no crane access at all. We build:

  • Derrick cranes and segment hoists
  • Beam launchers and cantilever carriers
  • Precision winching units
  • Heavy-lift platforms & straddle carriers

Handling equipment keeps material moving once the structure is in place. We produce:

  • Discharge systems
  • Monorail systems and spreader bars
  • Scissor tables and bulkhead handling machines

Custom Industrial Equipment Manufacturing for Infrastructure

Our business unit specializes in the design and manufacture of construction machinery and equipment. Every project starts with the client’s constraint rather than a product sheet. That constraint might be a pier geometry, a shaft diameter, or a fixed possession window.

Custom industrial equipment manufacturing at this level depends on keeping design, assembly and testing close together. Our team monitors the whole development process from early design through manufacturing and factory testing. Equipment is supplied as temporary construction plant or as permanent infrastructure equipment for inspection and maintenance.

Standard models exist where they make sense. Custom industrial equipment is engineered from scratch where they do not. Our integrated design services team supports early involvement at concept and tender stage.

Safety Is a Mindset

Working at height was the original business, and it set the way we still think about every machine we design. Safety is priority number one on every project we touch, and that mindset shows up before any standard is referenced.

We are not focused on one single rulebook. A segment hoist over a highway, a shaft elevator in a drive, and an overhead crane inside a reactor hall are three different safety problems, and each project adapts to the local safety and work standards that apply there.

Global Engineering. Proven on Complex Infrastructure.

This gives project teams access to specialist experience across permanent and temporary infrastructure equipment. Our work supports technically complex projects where standard equipment cannot meet the structural, spatial or operational requirements.

That experience includes major infrastructure projects in North America, Europe and APAC. These projects reflect the same approach we bring to each requirement: engineering a system around the structure and the way the project needs to operate.

Codes, Regulations and Standards

Requirements depend on equipment type, application and jurisdiction. A suspended platform in Europe and a nuclear lifting device in Canada answer to different frameworks. Project teams should confirm which apply before design freeze. 

We support projects from concept and feasibility through detailed design and manufacturing. Factory testing, installation and commissioning follow, with technical assistance during erection and trials. Once equipment is in service, we carry out inspections and safety compliance assessments of structural, drive, and electrical systems, as well as functional testing.
