A bucket-wheel excavator (BWE) is a large heavy equipment machine used in surface mining.

Their primary function is that of a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets them apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets which scoop material as the wheel turns. They are among the largest land or sea vehicles ever produced. The 14,200-ton Bagger 293 holds the Guinness World Record for the heaviest land-based vehicle ever built.

The Caterpillar D9 is a large track-type tractor designed and manufactured by Caterpillar Inc. It is usually sold as a bulldozer equipped with a detachable large blade and a rear ripper attachment.

The D9, with 354 kW (474 hp) of gross power and an operating weight of 49 short tons (44 t), is in the upper end of Caterpillar's track-type tractors, which range in size from the D2 69 kW (92 hp), 9 short tons (8.2 t), to the D11 698 kW (935 hp), 104 short tons (94 t).

The Caterpillar D10 is a bulldozer manufactured by Caterpillar Inc. between 1977 and 1987, when it was superseded by the D11. It was the first modern tractor to use the elevated drive sprocket to improve durability, operator comfort, and ease of maintenance.

A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Similar rollers are used also at landfills or in agriculture.

Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion.

The IDF Caterpillar D9 — nicknamed Doobi (Hebrew: דובי, for teddy bear) — is a Caterpillar D9 armored bulldozer used by the Israel Defense Forces (IDF). It is supplied by Caterpillar Inc. and modified by the Israel Defense Forces, Israeli Military Industries and Israel Aerospace Industries to increase the survivability of the bulldozer in hostile environments and enable it to withstand attack.

In the 1980s the IDF began modifying D9 bulldozers to incorporate armour. The bulldozers can also be fitted with weaponry such as machine guns and grenade launchers. There are various models, including a remote controlled version.

The Caterpillar D11T is a large bulldozer introduced by Caterpillar Inc. in 1986 to replace its D10. Weighing 248,500 pounds (112,700 kg), it is Caterpillar's largest and most powerful bulldozer. Mainly used in the mining industry, it is also employed to push-load scrapers, and rip rock overburden. D11s are manufactured in East Peoria, Illinois.
