Höhm Werner Degener didactic cutaway tandem trailer model in blue from the 1960s–1970s, built with wood and steel/aluminium components.
Description from the seller
The Höhm trailer is a highly precise cutaway didactic model manufactured in Germany between the 1950s and 1970s. They were used in driving schools to teach the mechanical operation of heavy vehicles and the articulation of trailers.
Main Features:
• Cutaway Design: The body is usually open or absent to reveal internal components such as the chassis, suspension, and braking system.
• Functional Mechanics: They include real-scale mechanical systems. The wheels rotate, the suspension cushions, and in the more advanced models the air or inertial braking system is representative of the real one.
• Noble Materials: They are built mainly from metal (steel and aluminum), wood, and rubber for the tires. They do not use plastics, which gives them considerable weight.
• Collectible Value: Today they are museum pieces or luxury items for collectors of technical automobilia. A complete truck-and-trailer set can reach very high prices at auctions of technical antiques.
The Höhm tandem trailers are exceptional pieces of technical collecting, designed to demonstrate advanced concepts of physics and mechanics applied to heavy-duty vehicles. These models were used to show how the tandem axle improves load distribution and directional stability, preventing all the weight from resting on the tractor’s hitch.
In driving schools of the era, the tandem model was essential for practicing reverse maneuvers. With a longer, steadier base, the steering response is less twitchy than with a short trailer, allowing the student to better understand the technical path before moving on to the real truck.
Technical Specifications of the Didactic Model
• Inertia Brake System (Overrun Brake): This is its most complex feature. The model lets you see how, when braking the car, the trailer’s inertia pushes on the hitch and mechanically activates the wheel drum brakes.
• Independent Suspension: Unlike single-axle models, tandem models typically show leaf springs or torsion-bar suspensions working together to maintain balance.
• Materials and Dimensions:
o Construction: Cast or machined steel chassis, with real rubber tires marked as "HOHM-MODELLE".
o Size: 110 cm long, weighing about 9 kg, reflecting their industrial robustness.
I haven’t cleaned it because if I do, I’ll surely keep it!
