Gripper and Grabber are twin tracked machines. Gripper is a mobile crane with a winch at his front and Grabber is an excavator with a bulldozer blade at his front.
They used to live in the city and once came to Sunflower Valley to help out Bob, Wendy and the machines build a sports stadium at Bobland Bay. After the sports stadium was complete, they went back home. Later on, they came back from the city to live at Sunflower Valley. A new shelter was built for them along with Bristle, Flex and Tumbler to stay in.
In Ready, Steady, Build!, they work at the Supplies Yard.
BasisGripper and Grabber are based on a CAT 314 D LCR.
- Their caterpillar tracks are based off Muck's.
- They both speak with a Scouse accent in the UK dub (southern drawl in US dub). They refer to others as "mates" in the UK dub ("partners" in the US dub) mainly due to stereotypical behaviours.
