Finally – fully hydraulic couplers are available to everyone. Fully hydraulic couplers have been around for many years but because of their high price, they were only ever used for special jobs. The simplicity of EC-Oil™ changes all this.
The new upgraded EC-Oil™ is engcon's system for the hydraulic and electrical connection of hydraulic tools and attachments, and is specially adapted for our new series of tiltrotators and our new, Q-Safe™ quick coupler. As sole supplier we are able to provide total solutions – from control systems, couplers and tools to support and safety analyses.
Use EC-Oil for instant tool and attachment changes directly from the cab. Using EC-Oil on the tool hitch, above and below the tiltrotator and on the tool itself you can, if necessary, under maximum breakout force disconnect from the tiltrotator and connect the quick coupler directly to a hydraulic or mechanical tool or attachment. This saves weight, which means fuel savings and a better overall economy. EC-Oil also includes automatically connected central lubrication. Together they create a system of tools that make your work proceed quickly, efficiently and profitably.
EC-Oil is designed for maximum operational safety in demanding environments. EC-Oil has no hoses or electrical cables that move around when connecting. This reduces the risk of pinch damage, wear and tear. EC-Oil is the market's only fully hydraulic coupler system able to handle the connection of pressurised tools and attachments at full system pressure. The proprietary oil and electrical connections are designed to be even more resistant to the tough conditions excavators often have to work in. The connectors are the most durable on the market – proven through burst tests at 400 bar operating pressure and field tests in dirty environments.
The new EC-Oil is available on engcon's new-generation tiltrotators, the new, Q-Safe™ quick coupler and all hydraulic tools and attachments from autumn 2013.
Flow rates – information EC-Oil
Regarding flow, it is also important to consider the back pressure that arises. High flow creates high back pressure. This also makes it difficult to provide general values as these depend on circumstances on the supply side from the machine and from EC-Oil to the tool concerned. It is necessary to consider the entire system's flow capacity in relation to current back pressure.
The flows below are calculated on the EC-Oil block in the excavator's quick hitch. Added to this is the back pressure up to the EC-Oil block and from the block to the tool concerned. Additional back pressure will occur with the use of a tiltrotator. However, it is difficult to provide an exact value as there are several factors to consider such as hoses, connection dimensions and bend radii etc.
Yet another factor is the tool itself (e.g. jackhammer, ground compactor etc.). Here, performance and maximum back pressure must be checked in each individual case.
Flows, Q-Safe machine hitch with one EC-Oil block.
EC-Oil 45 (3/8”) 32 l/min at 5 bar back pressure
EC-Oil 60 (1/2”) 75 l/min at 5 bar back pressure
EC-Oil 70 (3/4”) 125 l/min at 5 bar back pressure
Flows, Q-Safe machine hitch with twin EC-Oil blocks.
EC-Oil 45 (3/8”) 64 l/min at 5 bar back pressure
EC-Oil 60 (1/2”) 150 l/min at 5 bar back pressure
EC-Oil 70 (3/4”) 250 l/min at 5 bar back pressure
NOTE: These values are measured directly in and out of the blocks through the ECO connectors and reflect what the connectors in the block can handle. Once again, hose dimensions and the number of adapters in the line reduce values drastically. Also applies to the intended tool.
What is most important for you?
System engcon, centred around the tiltrotator, saves both time and fuel.
Fewer machine transits and less need for manual work mean increased safety at the workplace.
The tiltrotator's ability to tilt and rotate makes the machine a good all-rounder that carries out most tasks with greater precision.
Fewer machine movements and faster jobs mean less wear on the machine.
