Safety and comfort for agricultural machinery
Hydraulic systems are the backbone of modern agricultural and forestry machinery. They ensure that attachments, tipping trailers and other components can be operated reliably and efficiently. However, the connections between the machine and the attachment are particularly prone to risks in everyday use: Careless uncoupling, uncontrolled tensile load or an incorrectly loosened hose can quickly lead to oil loss, environmental pollution and expensive repairs.
With innovative breakaway couplings such as the STAUFF QRC-HP, the hydraulic connection is not only safer, but also more convenient. This generation of couplings enables one-handed coupling and automatic disconnection under tensile load - setting new standards for daily use in agriculture. This minimises downtime, protects the environment and makes work in the field noticeably easier.
From ISO-A to QRC-HP: What makes the coupling?
Hydraulic couplings are at the heart of modern agricultural and forestry technology. Quick-release couplings in accordance with ISO 7241-1 Series A (ISO-A couplings) are widely used, but conventional solutions pose practical challenges: coupling and uncoupling is often cumbersome and harbours risks such as hose breakage, oil loss and expensive machine downtime.
With the QRC-HP series, STAUFF offers an innovative alternative to the classic ISO-A coupling. The QRC-HP is designed in accordance with ISO 7241-1 Series A and ISO 5675 and sets new standards in terms of ease of use and safety.
Practical benefits: Single-handed coupling and automatic disconnection
The QRC-HP enables coupling and uncoupling with just one hand directly on the hose. In the event of excessive tensile load, the coupling disconnects automatically - a real advantage over conventional solutions, where both hands are always required and automatic disconnection is not possible. In the event of damage, this saves valuable time and costs, as oil losses and repairs are avoided.
Quality at a glance: Protection against oil loss and machine downtime
A hose rupture can lead to uncontrolled oil leakage, environmental pollution and high consequential costs. The QRC-HP prevents these risks thanks to its special design and ensures greater operational safety and less downtime. This not only protects the environment, but also your investment in machinery and equipment.
Technology and architecture: design and function of the QRC-HP
The coupling sleeve of the QRC-HP is not permanently installed at the rear of the machine, but remains freely movable. The sliding sleeve is attached to the bulkhead plate and can be moved in both directions. This makes handling particularly convenient and safe. Installation is carried out simply by fitting the sliding sleeve into the bulkhead plate - the coupling sleeve remains freely movable.
Retrofitting and integration
Mini-use case: typical application in practice
A farmer couples a hydraulically operated tipping trailer to his tractor. Thanks to the QRC-HP, he can connect the hose securely with just one hand and the coupling disconnects automatically when a tensile load is applied - without any loss of oil or damage to the hose. This keeps the work process efficient and safe.

FAQs
What is the difference between ISO-A and QRC-HP?
Can I retrofit the QRC-HP?
Yes, the coupling is suitable for retrofitting and original equipment.
How does automatic disconnection work?
In the event of excessive tensile load, the clutch plug is automatically released to prevent damage and oil loss.
Which machines is the QRC-HP suitable for?
For all standard agricultural and forestry machinery with hydraulic connection in accordance with ISO 7241-1 Series A and ISO 5675.
What advantages does the QRC-HP offer?
Single-handed coupling and uncoupling when installed in bulkheads, protection against hose rupture and thus massive oil loss and machine downtime.
How is the QRC-HP installed?
Installation is simply done by fitting the sliding sleeve into the bulkhead plate, the coupling sleeve remains freely movable.
