Performance as a function of the elevation angle ($\alpha$)

Variables C and D are interdependent, and their maximum values cannot be simultaneously attained; consequently, as the height of the barrier to be overcome increases, the maximum negative range decreases.

Advantages of the MEWP-N 150/160

Trade-off between range and capacity

The great advantage of this model is that it does not go to an extreme: the 150 offers a very solid payload for jobs involving more material or tools, and the 160 adds an extra metre of reach when geometry dictates.

Equipment prepared for technical intervention

The record includes 10 kVA of associated equipment and walkway scaffold with a 120 kg capacity, reinforcing its approach to maintenance and technical inspection beyond simple access.

Safety and operations in under-bridge work

Under-bridge MEWPs are specifically designed for negative work beneath structures, incorporating systems that guarantee operator safety and the continuity of work during the intervention.

Control and operation of the equipment

The operation is carried out from the working platform, allowing the technical team to maintain a direct and continuous view of the intervention area beneath the deck, which is key for inspection and maintenance work on bridges and viaducts.

Jobs where it fits best

Main applications of the underbridge truck-mounted platform

  • Technical inspection of bridges and viaducts
  • Replacement of bearings and neoprene pads
  • Installation of drainage systems and under-deck collectors
  • Installation of sensors for structural monitoring
  • Welding and repair work
  • Technical painting and abrasive blasting on metal structure
  • Interventions in areas where it is necessary to combine reach and payload without moving up to larger equipment

What jobs is the MEWP-N 150/160 used for?

Specialised applications for bridges and viaducts

The 150/160 N-type MEWP is especially suitable for under-bridge interventions that require good reach, working capacity and a reasonable site footprint. It is a very appropriate solution for bridges and viaducts with standard configurations, where the aim is to reduce operational complexity without losing technical intervention capacity. This fits with its overcomeable footpath limits of 2.7 m and maximum barrier of 3.5 m.

FAQs

Frequently asked questions about mobile elevating work platforms

The 150 prioritises load capacity, with up to 500 kg y 250 kg on the toe. The 160 gains an extra metre of under-counter reach, up to 16 m, but reduce the load to 300 kg y 150 kg on pointe.

It fits very well in bridges and viaducts with standard geometry where it is necessary to span up to 2.7 m of pavement and even 3.5 m of road safety barrier.

For inspection, maintenance, repair, drainage, sensors, technical painting, grit blasting and the replacement of bearings beneath the deck. The exact combination will depend on whether payload capacity or horizontal outreach is a greater priority.
