GF SK-S 36.20 Series
GF SK-S 36.20
For decades the technology for connecting tractor and trailer of a tractor trailer combination has not changed much. However, SAF-HOLLAND continues to invest actively in the further development of fifth wheels.
The result: The new fifth wheel called SK-S 36.20 is a spheroidal graphite cast iron construction.
It now weighs about 7 kilograms less than comparable products of competitors. The SK-S 36.20 is for the lightest approved 20-tonnes fifth wheel of its category.
Features and Benefits
|
|
Reliable and economic - A decision that is easy to make
The weight-optimised spheroidal graphite cast construction consists of a few wearing parts made of high-strength materials; if required, they can be replaced within about 20 minutes.
Their service life is as long as that of the tractor. This contributes decisively to the economic efficiency of the entire vehicle.
Ideal for tractor trailer combinations with payloads of up to 20 tonnes.

Features and Benefits
|
|
More Efficiency and More Safety
Growing deadline constraints and cost pressure are aggravating the competitive situation within the transport industry, with operational reliability and efficiency of a fleet increasingly turning into key management tasks: Efficiency is, therefore, the key demand which truck manufacturers and carriers will make on vehicles and their components – today and in the future. The fifth-wheel is one of the key components of a tractor: Its resistance to wear, its reliability and ease of operation affect the proper functioning of a tractor-trailer, making a considerable contribution to its safety and efficiency. These two factors can now be optimised further – with the RECOSS Safety Sensor System for all GF (Georg Fischer) fifth-wheels SK-S 36.20 by SAF-HOLLAND.
The RECOSS Safety Sensor System makes coupling safer and more comfortable. Three sensors monitor the status and functioning of the fifth-wheel electronically and indicate this visually and acoustically in the cockpit. RECOSS is available ex works for all GF (Georg Fischer) SK-S 36.20 fifth-wheels regardless of their specifications, e.g. low-maintenance plates or direct mounting, height-adjustable versions, in all available heights.
Sensors 1 and 2 on the coupler jaw and the safety latch continuously monitor the safety and correctness of the coupling operation. Sensor 3 monitors the presence of the semitrailer plate and ensures correct engagement and coupling height.
|
|
|
Less Stress
The driver has the obligation to ensure that the fifth wheel has closed properly and is safely locked – after each coupling operation and each break. With RECOSS at his side, he has an electronic assistance system which takes a considerable part of the strain off him: RECOSS reduces the accident risk and the number of unnecessary workshop visits because its three sensors not only indicate the correct coupling height but also monitor the coupling process continuously. Any deviations are immediately indicated in the cockpit both visually and acoustically.
|
|
|
Simple Retrofitting
A special RECOSS retrofit kit is available to enhance the efficiency of any GF (Georg Fischer) SK-S 36.20 fifth wheel in a simple and cost-effective manner. The entire coupling process can be monitored from the cockpit. This saves time and makes work easier: Efficiency combined with convenience.
|
|
|
Greater Economy
The GF (Georg Fischer) SK-S 36.20 with RECOSS is first choice for economic reasons, too: Fewer wear parts and high-quality coupling materials are repaid in the form of longer service life, and the additional safety gain achieved with RECOSS relieves strain on the driver and reduces the risk of tractor-trailer downtime.
