Spanish term

lanzadera de dovelas

Spanish to English Tech/Engineering Construction / Civil Engineering Road work
Context is roadwork (on bridges and overpasses) that is causing traffic delays and detours. A "lanzadera de dovelas" is being used on the job site. Found pictures online, but I'm not sure of the appropriate term in English.
The speaker is in U.S. Country of origin unknown.

Thanks in advance for your suggestions.

(formwork) launching gantry

As per references and with other peers' encouragement:

You may wish to word it a little differently, but:
http://www.berd.eu/en/produtos/lauching-gantries/
PRECAST SEGMENTS LAUNCHING GANTRY FOR THE CONSTRUCTION OF BRIDGES AND VIADUCTS WITH LARGE SPANS (BETWEEN 70 AND 120 METRES – BETWEEN 229 TO 393 FT.)), SPAN BY SPAN.

As Tom said "beam launcher" is another option, and as equally common.

Regards.

voussoir archs launcher

Peer comment(s):

neutral Thomas Walker : This probably has nothing to do with arches, or keystones or other voussoirs. This is about modern reinforced concrete bridge construction, using very heavy components & very big equipment.
