Italian construction machinery manufacturer Merlo, previously known mainly for its telehandlers, is increasingly positioning itself in the tunnel construction segment. With specialized machine technology, the company is targeting projects in underground construction – a sector that is growing in significance worldwide due to urban densification and the expansion of transport infrastructure.

From Telehandler to Tunnel Specialist

Merlo is expanding its portfolio beyond the classical applications of telescopic handlers. While these machines are traditionally used in agriculture, building construction and logistics, tunnel construction sites require specific technical requirements. The particular challenges in underground construction include limited space conditions, high safety standards for enclosed working environments and often special emission regulations.

The adaptation of construction machinery to tunnel conditions affects several technical aspects: compact design with simultaneously high lifting capacity, lighting systems for low-light environments, exhaust gas cleaning systems or alternatively electric drives, and reinforced safety equipment. For Merlo, the step into this specialized market represents a technical reorientation of established product lines.

Growth Market Underground Construction

The timing of this move is strategically chosen. Numerous tunnel construction projects are in planning or execution worldwide – from subway expansions in major cities to road tunnels for traffic relief to supply tunnels for energy infrastructure. Increasing urban densification is raising the demand for underground structures, as above-ground available space becomes scarcer.

Climate policy factors also play a role: the expansion of rail transport as an alternative to road transport requires new tunnel routes, while flood protection projects increasingly incorporate underground storage systems. These developments are creating a growing market for specialized construction machinery that goes beyond classical tunnel boring machines and also includes auxiliary equipment such as transport vehicles, lifting platforms and indeed telescopic handlers.

Technical Requirements in Tunnels

Working conditions in tunnel construction differ fundamentally from surface construction. Machine manufacturers must develop specific solutions for this environment. The spatial constraints in tunnel tubes demand compact dimensions and tight turning radii. At the same time, load capacity and lifting height must not be compromised, as heavy materials such as tunnel lining components, reinforcement elements or supply lines must be moved.

Emission standards are particularly critical. In closed spaces with limited ventilation, combustion engines can produce health-hazardous exhaust gas concentrations. Many tunnel projects therefore mandate electrically operated machines or demand state-of-the-art exhaust gas cleaning with particle filters and catalytic converters. For manufacturers, this means additional development costs, but simultaneously also the opportunity to differentiate itself through technological competence.

Competitive Environment in the Underground Segment

With its tunnel construction focus, Merlo is entering a segment where established competitors are already active. Manufacturers such as JCB, Caterpillar and Liebherr also offer machines for underground applications, often with decades of experience in mining and tunnel construction. These competitors have extensive reference projects and established relationships with tunnel construction companies.

For a comparatively smaller manufacturer like Merlo, market entry therefore represents a particular challenge. Success will depend on whether the company can offer technical unique selling points – whether through particularly compact design, innovative drive concepts or lower total operating costs. Service readiness also plays a decisive role in project-driven tunnel construction, as machine downtime can cause substantial delay costs with tight schedules.

Strategic Diversification

The move into tunnel construction fits into a trend toward diversification among construction machinery manufacturers. Specialized market niches promise higher margins than hotly contested standard segments. Furthermore, manufacturers can utilize their existing technology base and tap into new customer groups through targeted modifications.

For Merlo, the tunnel construction orientation could also be the entry point into further underground applications. Beyond classical traffic tunnels, demand is growing for underground facilities for supply, disposal and storage. Data centers, logistics facilities and even agricultural production plants are increasingly being constructed underground. Each of these applications requires specialized construction equipment.

Outlook for Operators and Contractors

For tunnel construction companies, the market entry of additional manufacturers could have positive effects. More competition tends to lead to technical innovation and more competitive prices. However, it remains to be seen what concrete product solutions Merlo has developed for the underground sector and how these prove themselves in practice.

The coming months will show whether Merlo can actually conquer significant market share with its tunnel construction strategy or whether the dominance of established providers is too great. The decisive factor will be whether the company not only delivers technically convincing machines but can also build the necessary service and support network for demanding infrastructure projects.
