The Caterpillar 725 ADT in 1:50th scale was released by Norscot in 2004 with #55073.
The level of detail on the model is resonable. The front grill has work lights with painted lenses along with the Caterpillar name across the front grill. The cab has a nice looking interior.
But the model Caterpillar 725 has sadly too thick plastic safety rails and mirrors. The rubber tyres have a well defined tread pattern but unfortunaly the wheels are made of plastic. The functional articulated steering uses hydraulic cylinders for a little extra realism. The dump bed can be tipped to a reasonable angle and black painted metal mud guards have been cast on the bed which is a nice addition.
The rear wheels are mounted to a pivoting suspension bar which is another nice touch, demonstrating the suspension system on the full sized truck. The paint finish is very good with accurate placement of the Caterpillar markings.
Caterpillar 725 Articulated Dump Truck with 26 ton (23.6 tonnes) rated payload offers proven reliability and durability, high productivity, superior operator comfort and lower operating costs.
Spacious two-person cab with forward facing trainer/passenger seat and off-road oil/nitrogen front suspension cylinders keep the operator comfortable through out the working day. True "on-the-go" differential locks with simple operation improve cycle times and productivity.
Strong durable Caterpillar C11 ACERT engine and electronically controlled transmissions deliver 301 pk high productivity with low fuel consumption.
