TILTROTATOR manufacturer Engcon is to begin production on its largest automatic hydraulic connector to date – the EC-Oil 80.
The connecter is intended to allow large, high-flow tools to be quickly and easily connected to excavators up to 40-tonnes using the Q-Safe 80 hitch. This means the operator can remain seated when connecting or disconnecting the tiltrotator and other hydraulic tools, Engcon explained.
This is said to make the Q-Safe 80 Engcon’s “most powerful” automatic quick hitch so far. The system will come with an EC-Oil 70 block, two 3/4 inch connectors and connections for electrical power and central lubrication as standard, allowing automatic connection to Engcon’s tiltrotators with equivalent EC-Oil connectors.
The standard configuration is said to allow hydraulic flows of up to 250 litres through the Q-Safe 80 quick hitch. If a higher flow is required, the EC-Oil 70 block can replaced with an additional EC-Oil 80 block, two 1-inch hydraulic connectors and 1/2 inch hydraulic connector and two electrical power connections to reach a flow of 300 litres, enabling the connection of large, high-flow hydraulic tools.
Fredrik Jonsson, research and development manager at Engcon Group said, “There is great demand for an automatic quick hitch for large excavators, as the large manual hydraulic connectors from 3/4 inch upwards are heavy and difficult to handle. EC-Oil 80 can transform connections for large excavators and tools, so that jumping in and out of the machine and struggling with awkward, pressurised, messy hydraulic connectors will be a thing of the past.”
Engcon began testing the prototype for the EC-Oil 80 in 2018. The model is expected to enter full-scale production in spring 2019.
