Every so often a creation comes along that shifts what we thought possible from LEGO bricks. This is one such creation. Created over the course of a year by Technic-building legend Sariel this is a fully working replica of JCB’s 5CX Wastemaster backhoe, powered by pneumatics, eleven Power Functions motors, and two third-party SBricks.
Underneath the brilliant Technic exterior are nine motors that drive all four wheels, the three-mode steering (two-wheel, all-wheel and crab), backhoe arm rotation and traverse, and powering a combination of pneumatic cylinders and linear actuators to control both the front and rear arms and their respective buckets. A further two motors power the pneumatic ‘remote control’, compressing the air which travels down twelve separate hoses to the model itself.
A motorised remotely rotating driver’s seat and a suite of LED lights from third-party lighting specialists Brickstuff complete the electronics, making this 2.4kg, 75 stud-long masterpiece one of the most technically advanced Technic creations to date. There is much more to see of Sariel’s amazing remote control JCB at the Eurobricks forum, on Flickr, and at Sariel’s excellent website, you can watch it in action via the video below, and if you’d like to build your own model with many of the features of this one we highly recommend LEGO’s own 42054 Claas Xerion 5000 set, which share its wheels and amazing three-mode steering with Sariel’s fantastic creation.
