Mef express - Aerial tube bundle extractors for heat exchangers "on shore"

MAUS ITALIA proposes its NEW complete range of Mef express aerial extractors for the extraction and insertion of tube bundles on the plant for maintenance operations even at considerable distances from the ground.
Years of product evolution have allowed a complete reinterpretation of the design which makes MAUS ITALIA overhead tube bundle extractors today even more lightweight, more flexible and easier to handle.

  • For tube bundles up to 125 T weight

Mef express main features



Mef express - Maus Italia

No damage

The Mef express extractor carefully supports the tube bundle during extraction and insertion and ensures perfect balancing along its longitudinal axis eliminating the risk of damaging the diaphragms or crushing the tubes.

Mef express - Maus Italia

Operational simplicity

The controls on the machine or on the supplied remote control make the Mef express extremely easy and intuitive to use, guaranteeing the operator control of the extraction sequence.

Mef express - Maus Italia

Long-lasting epicyclic power

Thanks to powerful planetary gearboxes, the aerial Mef express develops a high pulling/thrust force, thus minimising maintenance interventions.

Extraction sequence



Aerial tube bundle extractors Mef express Maus Italia




Easy container transport


For sizes beyond the Mef express 2045/75, the lifting ring can be disassembled into 3 parts to allow the extractor to be shipped in standard containers.

Mef express Maus Italia

Hydraulic balancing system


Two powerful hydraulic pistons allow the extractor to be balanced by modifying, if necessary, the position of the frame with respect to the ring attached to the crane

Mef express Maus Italia

Bundle supports with manual adjustment


The correct housing of the tube bundle is guaranteed by the support trolleys which, by leaning on the baffles, support it safely without compromising its integrity

Mef express Maus Italia

Long-lasting epicyclic power


Powerful planetary gearboxes (from 1 to 3, depending upon the pulling force) permit the Mef express to develop a pulling/thrust force suitable for high loads and to minimise maintenance interventions on the transmission components

NEW / PATENTED: Telescopic arms for the thrust and rotation of the tube bundle

Innovative remote-controlled system for rotating the tube bundle which allows safe alignment of the tube bundle with the shell, thus avoiding operator intervention above the machine during the final insertion phase.

EOC: Electronic Overturning Control system

Innovative control system that allows the aerial handling of loads in total safety, inhibiting any incorrect commands that would compromise the stability of the Mef express.
