Going beyond hydraulics

Welcome Electronic Direct Drive

Electronic Direct Drive (EDD) Technology brings forth a new era of electronic, mobile and reliable rescue equipment, direct from the motor to output force and highly-efficient for a long running time.

There is no need for hydraulic fluids, pump, valves or seals. Rescuers can simply direct from a compact, powerful and efficient motor that drives a screw piston.

Why the electronic direct drive?

EDD gives rescue workers efficiency for long running times. The fewer steps needed to get power the more efficient a system becomes. Hydraulics is not ideal for battery operated systems but until now it was the only way to achieve the necessary force.

How is it possible to exclude hydraulics?

The motor technology now available is what makes this achievable. These new motor technologies are powerful, compact and efficient enough making it possible to go direct without the need for using hydraulics in the system. The motor technology leveraged is similar to a small gasoline engine currently used in hydraulics pumps. The motor itself drives a robust screw or in the case of the P4 a robust gearbox. Nothing more is needed.

Highly-efficient for long running times

Each single component used in a rescue tools requires energy for operation. EDD allows RESQTEC to exclude the hydraulic fluid and pump from the rescue tool which reduces efficiency loss enormously. EDD delivers long run times at full speed. Each tool is powered by the latest lithium-Ion technology. The battery conforms to the IEC 62133 safety standards and the UN 38.3 shipping requirements for lithium batteries.

On the other hand, the hydraulic system (pump, fluid, valves etc.) all reduce efficiency. Eliminating hydraulic fluid and pump in the system reduces/improves this loss of efficiency. Delivering long run times at full speed makes EDD super-efficient.

Direct force for increased performance

Integrated hydraulic rescue tools get force by building up pressure. EDD is direct; it delivers a constant maximum force. The tool’s reaction and response is immediate for great cutting and spreading performance.

Full variable speed

Whereas hydraulic systems don’t allow full control over the speed, EDD does let you be in full control. The control handle works in a similar way to an accelerator; just open it for optimum control. This is an important benefit when working close to a victim.

Heat, durability and maintenance

Integrated hydraulic systems tend to heat up which can create all kinds of problems. The current integrated tools have little room (small reservoir) needed to cool down the hydraulic fluid in its system, limiting the running time. However, EDD is not affected by heat issues. It therefore can provide a much longer running time. EDD is highly durable and requires little to no maintenance. It works well in hot and cold environments.

Hydraulic rescue tools work at high pressures and are carried close to the body. EDD contains no hydraulic fluid under pressure nor a pump or seals. A less obvious though important advantage is the lack of compression within the system. Compression of hydraulic fluid creates spring reaction forces. EDD has no such fluid compression. It is the safest choice for rescuers.

All-weather proof

It is vital that rescue tools are all-weather proof. The ingenious design and military grade connector with IP66 value and rating makes these new tools most suited to work in heavy rain showers.

Ergonomic compact design

The battery has been positioned underneath the tool which minimizes the tool’s length and allows easy changing of positions. In addition, the control handle in the centerline contributes to an optimum aligned tool. There simple features deliver you increased flexibility in tight spaces or small areas.
