Excavators come in a wide variety
The smaller ones are called a mini-excavator or compact excavator.
years, hydraulic excavator capabilities have expanded far beyond
excavation tasks. With the advent of hydraulic powered attachments such
as a breaker, a grapple or an auger, the excavator is frequently used in
many applications other than excavation. Many excavators feature
quick-attach mounting systems for simplified attachment mounting,
dramatically increasing the machine's utilization on the job site.
Excavators are usually employed together with loaders and bulldozers. Most wheeled versions, and smaller, compact excavators have a small backfill (or dozer-) blade. This is a horizontal bulldozer-like blade attached to the undercarriage and is used for pushing removed material back into a hole.
Excavators are also called diggers and 360-degree excavators, some times abbreviated simply to a 360. Tracked excavators are sometimes called trackhoes by analogy to the backhoe. Even though the 'back' in backhoe refers to the action of the bucket (which pulls "back" toward the machine) and not the location of the shovel, excavators are also occasionally referred to as fronthoes or even just "hoes" .

Dump trucks or production trucks are those that are used for transporting loose material such as sand, dirt, and gravel for construction.
The typical dump truck is equipped with a hydraulically operated open box bed hinged at the rear, with the front being able to be lifted up to allow the contents to fall out on the ground at the site of delivery.
Dump trucks come in many different configurations with each one specified to accomplish a specific task in the construction chain.
Standard dump truck:
The standard dump truck is a full truck chassis with the dump body mounted onto the frame. The dump body is raised by a hydraulic ram lift that is mounted forward of the front bulkhead, normally between the truck cab and the dump body.
The standard dump truck also has one front axle, and one or more rear axles which normally has dual wheels on each side. The common configurations for standard dump trucks include the six wheeler and ten wheeler.
Transfer dump truck:
For the amount of noise made when transferring, the transfer dump truck is easy to recognize. It's a standard dump truck that pulls a separate trailer which can be loaded with sand, asphalt, gravel, dirt, etc.
The B box or aggregate container on the trailer is powered by an electric motor and rides on wheels and rolls off of the trailer and into the main dump box. The biggest advantage with this configuration is to maximize payload capacity without having to sacrifice the manoeuvrability of the short and nimble dump truck standards.
Semi trailer end dump truck:
The semi end dump truck is a tractor trailer combination where the trailer itself contains the hydraulic hoist. The average semi end dump truck has a 3 axle tractor that pulls a 2 axle semi trailer. The advantage to having a semi end dump truck is rapid unloading.
Semi trailer bottom dump truck:
A bottom dump truck is a 3 axle tractor that pulls a 2 axle trailer with a clam shell type dump gate in the belly of the trailer. The biggest advantage of a semi bottom dump truck is the ability to lay material in a wind row. This type of truck is also manoeuvrable in reverse as well, unlike the double and triple trailer configurations.
Double and triple trailer:
The double and triple bottom dump trucks consist of a 2 axle tractor pulling a semi axle semi trailer and an additional trailer. These types of dump trucks allow the driver to lay material in wind rows without having to leave the cab or stop the truck. The biggest disadvantage is the difficulty in going in reverse.
Side dump trucks:
Side dump trucks consist of a 3 axle trailer pulling a 2 axle semi trailer. It offers hydraulic rams that tilt the dump body onto the side, which spills the material to the left or right side of the trailer. The biggest advantages with these types of dump trucks are that they allow rapid unloading and carry more weight than other dump trucks.
In addition to this, side dump trucks are almost impossible to tip over while dumping, unlike the semi end dump trucks which are very prone to being upset or tipped over. The length of these trucks impede manoeuvrability and limit versatility.
Off road dump trucks:
Off road trucks resemble heavy construction equipment more than they do highway dump trucks. They are used strictly for off road mining and heavy dirt hauling jobs, such as excavation work. They are very big in size, and perfect for those time when you need to dig out roads and need something to haul the massive amounts of dirt to another location.
