Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house".The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which uses winches and steel ropes to accomplish the movements.
Garbage truck or dustcart refers to a truck specially designed to collect municipal solid waste and haul the collected waste to a solid waste treatment facility such as a landfill. Other common names for this type of truck include trash truck in the United States, and rubbish truck, bin wagon, dustbin lorry, bin lorry or bin van elsewhere. Technical names include waste collection vehicle and refuse collection vehicle. These trucks are a common sight in most urban areas
A tow truck (also called a wrecker, a breakdown truck, recovery vehicle or a breakdown lorry) is a truck used to move disabled, improperly parked, impounded, or otherwise indisposed motor vehicles. This may involve recovering a vehicle damaged in an accident, returning one to a drivable surface in a mishap or inclement weather, or towing or transporting one via flatbed to a repair shop or other location.
A tow truck is distinct from a motor carrier that moves multiple new or used vehicles simultaneously in routine transport operations.
A fire engine (also known in some territories as a fire apparatus, fire truck, or fire appliance) is a vehicle designed primarily for firefighting operations. In addition, many fire departments often employ their vehicles for various other uses including emergency medical services and rescue purposes. The terms "fire engine" and "fire truck" are often used interchangeably but in North America represent different types of vehicles.
The primary purposes of a fire engine include transporting firefighters to an incident scene, providing water with which to fight a fire, and carrying other equipment needed by the firefighters. A typical modern vehicle will carry tools for a wide range of firefighting and rescue tasks, with common equipment including ladders, a self-contained breathing apparatus, ventilating equipment, first aid kits, and hydraulic rescue tools.
Many fire vehicles are based on standard vehicle models (although some parts may be upgraded to cope with the demands of the vehicle's usage). They are normally fitted with audible and visual warnings, as well as communication equipment such as two-way radios and mobile computer technology.
