Cat’s Claw – Picture Special

Lego Technic Caterpillar 390F

TLCB favourite shineyu is back, and for his latest build he’s built big. This spectacular creation is a fully working replica of the Caterpillar 390F, and it’s absolutely packed with stunning engineering.

Inside the lifelike bodywork are a range of Power Functions motors and infrared receivers that allow the complete remote control of all of the Caterpillar’s functions.

These include independent drive to each track with skid-steering, a motorised turntable enabling the rotation of the superstructure, and a powered on-board compressor.

Able to generate its own air pressure shineyu’s Caterpillar uses LEGO’s pneumatic system to control the boom arm’s elevation and extension, as well as the movement of the grab/claw-type thingumy mounted on the end (if you know what this is actually called let us know in the comments!).

With four small pneumatic cylinders the claw is powerful enough to lift a variety of fruits (lemon pictured above), or – if your a TLCB Elf – grab your head really very tightly indeed and then drop you in the food recycling bin. It was strictly in the name of research…

Anyway, whilst we explore the multitude of ways in which this incredible creation can be put to use terrorising our slovenly workforce you can check out all of the top-quality images via the discussion on the Eurobricks forum – click here to join in.
