For what jobs is the N 170/190 MEWP used?
Applications in high-demand infrastructure
The PEMP-N 170/190 it is designed for under-bridge interventions on large bridges and viaducts, where greater horizontal reach and a high load capacity are required for complex technical work.
It allows action on structures with large overhangs, greater barrier heights and demanding configurations, maintaining stability and efficiency throughout the intervention.
What jobs is the PEMP-N 150/160 PLUS used for?
Specialised applications in complex structures
The PEMP-N 150/160 PLUS is designed for under-bridge interventions on bridges and viaducts with complex geometries, where conventional access is limited or inefficient.
Thanks to its ability to clear pavements of up to 3.9 metres and negotiate higher parapets, it makes it possible to work on structures with large overhangs, elevated safety barriers or irregular configurations, reducing the need to reposition the vehicle to a minimum.

FAQs
Frequently asked questions about negative mobile elevating work platforms MEWP-N
What is a 170/190 MEWP?
It is a truck-mounted mobile elevating work platform designed as an under-bridge access unit for negative work, particularly suited for the inspection and maintenance of bridges and viaducts.
What is the difference between the PEMP-N 170 and the 190?
The PEMP-N 170 prioritises load capacity, with up to 800 kg on the catwalk and 400 kg at peak, whereas the PEMP-N 190 extend the horizontal scope to 19 m, although it reduces the maximum load to 650 kg y 250 kg on the toe.
What is the range of this equipment?
According to configuration, it works with 17m or 19m horizontal under-bridge reach and with 8 m negative vertical reach.
For what type of bridges is it recommended?
It is particularly suitable for bridges and viaducts where a long under-bridge reach, good load capacity and the ability to clear footpaths of up to are required 2.6 m and road safety barriers of up to 5 m.
What jobs does it allow you to do?
It is suitable for technical inspection, support replacement, sensor installation, drainage and collector systems, as well as repair, welding, abrasive blasting and technical painting work beneath the deck. This type of use fits the PEMP-N category in Transgruma's catalogue for structural maintenance and inspection.
What technical equipment does it feature?
The record shows 10 kVA equipment y scaffolding on walkway with a 120 kg capacity (1 person).
Is it hired with an operator?
Yes, the Transgruma service is offered as hire with a specialist operator for these types of technical interventions on bridges and infrastructure. Additionally, the contracting company can have properly trained specialist technical equipment at its disposal. Transgruma offers specific MEWP-N operator training.
