Hellmut Ernst: The Engineer Behind the Aparatos De Elevacion Y Transporte Hellmut Ernst was a German engineer who specialized in the design and construction of lifting and transportation devices, such as cranes, elevators, conveyors, and cableways. He wrote a three-volume book titled Aparatos De Elevacion Y Transporte (Devices
of Lifting and Transportation), which was published in Spanish by Blume in 1969[^3^]. The book is considered a classic reference in the field of mechanical engineering, covering the principles, calculations, and applications of various types of lifting
and transportation devices.

The first volume of the book deals with the general theory of lifting and transportation devices, such as forces, moments, stresses, strains, power, efficiency, safety factors, and materials. It also introduces the basic elements of these devices, such
as ropes, chains, pulleys, drums, gears, brakes, clutches, motors, and controllers[^1^]. The second volume focuses on the specific types of lifting devices, such as cranes, hoists, winches, elevators, escalators, and aerial ropeways. It describes their
classification, characteristics, design criteria, and examples[^2^]. The third volume covers the specific types of transportation devices, such as conveyors, belt systems, bucket elevators, screw conveyors, pneumatic transporters, and pipelines. It
explains their classification, characteristics, design criteria, and examples[^4^].
Hellmut Ernst's book is a comprehensive and practical guide for engineers, technicians, students, and anyone interested in the field of lifting and transportation devices. It provides a solid theoretical foundation as well as numerous practical examples
and illustrations. It is a valuable resource for learning about the history, development, and current state of the art of these devices.
Hellmut Ernst was born on September 19, 1903 in Zeiden, a town in Transylvania that was part of the Austro-Hungarian Empire at the time. He studied mechanical engineering at the Technical University of Munich, where he graduated in 1928. He then worked
as a design engineer for various companies, such as Siemens, MAN, and Demag[^1^]. He also taught as a lecturer at the Technical University of Nuremberg from 1947 to 1966[^1^].
Hellmut Ernst was a pioneer in the field of lifting and transportation devices, especially cranes. He developed several innovations and patents, such as the first electrically driven tower crane, the first mobile crane with a telescopic boom, and the
first hydraulic crane with a variable load moment limiter[^1^]. He also contributed to the standardization and regulation of these devices, such as the DIN 15018 standard for cranes and the VDI 3576 guideline for crane safety[^1^]. He was awarded several
honors and distinctions, such as the Diesel Medal in 1954 and the Honorary Doctorate from the Technical University of Munich in 1963[^1^].
Hellmut Ernst died on February 14, 1966 in Nuremberg at the age of 62. He left behind a legacy of scientific and technical achievements that have influenced and advanced the field of lifting and transportation devices. His book Aparatos De Elevacion Y
Transporte is still widely used and cited by engineers and researchers around the world.
