BACKGROUND AND DESIGNER
Founder of Excavator Forklift, James Russell (B.Sc.(Eng)C Eng M.I.E.I), came up with the idea for these innovative attachments when he had a heavy lifting requirement and only a small excavator on site. The concept of the "Original" Type 1 and Type 2 EFLs was born.
After investing many man-hours further developing the idea and refining the product, the "NextGen" Type 3 and Type 4 were developed. These, our current High and Low lift models, combine the mechanics of the earlier Types and the genius of a wheelbarrow, further boosting lifting power with a design that requires a less bespoke fit.
James' design has allowed him to harness the hydraulic pressure of mini-excavators which is normally focussed on excavating. Since the attachment facilitates a lift that is "all up" rather than "up and out", the tipping point which would otherwise be reached can be avoided. See our FAQ for more on this topic.

THE PROBLEM
Diggers are designed to maximize digging efficiency. Their shape means they tip if lifting heavy loads.
Traditional excavator forks contribute to the overturning moment. They are ineffective for machines less than 7 tonnes.
The EFL re-directs the hydraulic pressure to create a vertical lift while the attachment wheels support the load, resulting in impressive lift capacity.
THE SOLUTION
It is the attachment that lifts. The digger provides ballast, hydraulic pressure and the user interface for EFL controls.
