When is a Dumper not a Dumper, when it’s a Grumper!

While surfing the web over the weekend, this new concept caught my eye somewhat unexpectedly!

The “Grumper” is the brainchild of an engineering team at Lincolnshire and London based contractors JJ Mac Ltd and is effectively a new self-loading dumper concept. But where this concept differs from traditional self-loading dumpers is that the skip itself is designed to grab the material in a clamshell style movement.

Of course, there have been many self-loading dumpers produced previously, fitted with front mounted loader arms and bucket, which do tend to look vulnerable to damage in the wrong hands, but the “Grumper” with its hydraulically operated grabbing system, is a totally different approach to the concept.

Details are sketchy at the time of writing, but as I understand it the “Grumper” can be manufactured to fit all OEM site dumpers in the 3-tonne size class, and potentially larger going forward.

It will be interesting to see how this progresses in due course, checkout the video from JJ Mac Ltd below.
