Promove SG 6.11 roterende sorteringsgrab · gravemaskiner 6–11 t
Rotating sorting grab for Volvo ECR88D
The Volvo ECR88D is a short-tail midi excavator with an operating weight of 8.75–9.38 t, inside the Promove SG 6.11 class (6–11 t). With the sorting grab it becomes a sorting and loading machine for recycling yards, strip-out work and timber or stone handling.
The SG 6.11 needs two separate circuits: one for opening and closing (30–40 l/min, max. 300 bar) and a small one for rotation (10–15 l/min, max. 150 bar). According to Volvo, the ECR88D offers a double-acting X1 circuit with 68 l/min and a circuit for tilt or rotating attachments with 28 l/min. Both deliver more than the grab needs, so flow, and on the rotation circuit also pressure, must be limited.

Frequently asked questions
Why does the grab need two circuits?
One circuit moves the shells, the second rotates the grab, so you do not have to switch between opening/closing and rotating.
What happens if the rotation circuit delivers too much oil?
The grab rotates too fast and the rotation drive is overloaded. Promove limits rotation to 10–15 l/min and 150 bar. These values must be set on the ECR88D or limited with valves.
Is a quick coupler included?
No. You receive the grab with top plate and hydraulic hoses. Quick coupler, adapter plate and adapters are not included. For the SG 6.11, any quick coupler or mount is to be confirmed with the manufacturer before we quote.
Check both circuits, then order
Send us model, operating weight, quick coupler and the data of both auxiliary circuits (l/min, bar) of your Volvo ECR88D. We reply with fit and a written quote in EUR, with freight as a separate line.
