Scraper Evolution Series Exclusively from Diecast Masters: Continuing our special Evolution Series, Diecast Masters is proud to introduce highly detailed scale models of the Cat® No. 70 and 621K Wheel Tractor-Scraper. These newest releases join the Motor Grader, Track-Type, Wheel Loader, Track Loader and Off-Highway Trucks Evolution models previously introduced. Defining Scraper Technology from the 1940s Through Today: Diecast Masters pays homage to the rich history and remarkable sweep of earthmoving technology, beginning with some of the earliest machines and extending to the most recent. This story of Cat® scrapers is the sixth installment of the Evolution Series.
The design and size of the big Cat® track-type dozer with its protruding delta crawler track impresses everyone that looks at it. When developing our model, we wanted to remain true to this so we created an impressive toy and model that is, as is the case for all our products, just like the real thing. These machines are mainly used on large construction sites and in mining regions to level large areas. Of particular note is the fully functional link track that consists of 62 links and shows no weakness even in the rough, challenging conditions it is subjected to daily (sand pit). The height and inclination of the mighty levelling blade can be adjusted. The height of the impressive scarifier can be adjusted. The cab doors can be opened to let figures into the track-type dozer to make the game just like reality. So there is nothing to stop small children playing realistic games with this power machine in their bedroom or outside.
This type of tool, referred to as a track type tractor in technical jargon, is used for heavy digging and clearing - even in difficult terrain - up to fine levelling.
