Seven Liebherr cranes. 184-tonne girders. And a hard deadline every single morning: the M-30 opens at 6 a.m. whether you are finished or not.
Madrid is putting a 16,000-square-metre pedestrian and green zone directly over the M-30 urban motorway, stitching the Salamanca and Ciudad Lineal districts back together. Somebody has to fly the deck that the park sits on. That somebody was Grúas Aguilar.
The company brought seven machines to the job — six LTM mobile cranes ranging from 95 to 800 tonnes of capacity, plus an MK 140-5.1 mobile construction crane.
Note what that spread means in practice. This was not one big crane doing everything. It was a matched fleet where each machine was sized to its piece, which is how you keep a job like this moving instead of waiting on one overworked unit.
Every lift happened between 10 p.m. and 6 a.m. The M-30 is one of Madrid's busiest arteries — shutting it down during daylight was never on the table. So the crew got an eight-hour window, and the motorway had to reopen before the morning commute.
That constraint changes everything upstream. Rigging gets staged before dark. Setup has to be right the first time, because there is no "we will finish it tomorrow" when tomorrow means tearing back down and clearing the roadway. Eight hours, every night, on repeat.
Luis Aguilar, the company's owner, was direct about where the job was actually won: "We were involved in technical planning and developing lifting concepts from early stages."
That is the part clients rarely see on an invoice. By the time a 184-tonne girder is in the air over a live motorway, the hard thinking is months old. Liebherr's service team backed the execution, but the lift concept came from the crane company being in the room early.
Grúas Aguilar has been at this since 1968, working out of a base near Madrid. They run more than 200 mobile cranes, and over 90 percent of that fleet is Liebherr. When a company standardizes that hard, it is usually about parts, training, and service response — not badge loyalty.
Parque Ventas is scheduled to wrap in spring 2027.
There is a specific kind of operator who thrives on a 10 p.m. to 6 a.m. window over a highway. Empty road, work lights, radio chatter, and a load that does not care what time it is.
If that is your shift, we make gear for it. Take a look.
