Hanover, Germany: Trailer maker Schmitz Cargobull continues to challenge the supremacy of Carrier Transicold and Thermo King for fridges and is extending its all-in-one reefer package by launching a multi-temperature fridge at the Hanover Show.
In 2012 Schmitz launched its first own brand fridge, a mono temperature unit. Around 300 Schmitz T.KM One fridges underwent in-service trials on Schmitz trailers with operators in Germany, the Netherlands and Denmark.
The T.KM One is an all-electric design, with a four-cylinder, 2.2-litre Perkins diesel engine driving a generator that supplies power to the electrically driven compressor and fans. Engine speed control is continuously variable rather than stepped, and two of the compressor’s four cylinders can be de-activated to save fuel when cooling demand is low.

New trailer frame design
Schmitz Cargobull has a new trailer chassis design that replaces conventional I-beam main chassis rails with a Z-beam rail. The new rails are cold-rolled flat strips of steel, stronger and cheaper to make.
Z-beams have a thicker web than Schmitz I-beams: 7mm rather than 4mm for a standard curtainsider. Beam depth remains at 400mm, with a 120mm neck for a 15-tonne rating. Extra strength is added forward of the landing legs by bolting one of several reinforcing neck modules to the Z-beams.
The spring hanger-brackets are bolted to the bottom flanges of the main rails, through the rail’s web, reckoned to give a more stable connection. Schmitz says build precision is better as the absence of welding eliminates risk of heat deformation.
The first trailers with Modulos Z-beam chassis are curtainsiders, now called Genios, and by the end of the year 75% of Schmitz output will feature Modulos chassis.
