Rental construction equipment includes tractors and bulldozers and can accommodate a number of performance scenarios. Excavators exist in many sizes from caterpillars to massive-sized vehicles intended for extensive projects. These variations show how versatile excavators are and why construction equipment rentals
are so prevalent in many industries. Construction Equipment Rentals: Excavator
The first excavator emerged around 1839 when inventor William Smith Otis created the steam shovel. This shovel functioned through a set of pulleys that operated a scoop called a ‘bucket” for deep, continuous digging.
The growing demand led to hydraulic design to meet quicker production and inevitably brought about the advent of the electric motor. By the early twentieth century, excavation had become an independent industry with standards of its own.
Excavators are now a prime source for societal growth and so all kinds of rental construction equipment are in use in private and public sectors.
The typical excavator consists of two sections: the undercarriage and house. The former contains four parts—the blade, track or wheels, track/wheel frame and the driver motor with gearing—all of which work together to provide mobility. The counterweight engine, operator cab and fuel/hydraulic tanks make up the house, which serves as the source of navigation. The connection of the two sections by a central pin facilitates a 360-degree rotation of the house for easy performance.
The main boom, secured to the house, comes in four possible designs relative to movement:
• Mono Boom – up and down
• Knuckle Boom – up, down, left and right
• Triple Articulated Boom (TAB)
• Pivot Boom (small excavators)
The boom assembly includes two additional pieces: the stick and the bucket. The stick is a hydraulic extension erected on a joint that provides the force of power. The bucket has either a straight edge or a row of ‘teeth’ for hard work. The operation of these features relies on two x-y joysticks and a switch for selection between SEA and ISO control configurations.
Excavators also show their versatility in performance: digging trenches, cracking ice, transporting materials, forest brush cutting, structural demolition, mining, river dredging, pike driving and leveling. These are common tasks, but the list is far more extensive.
Excavators have come a long way since their inception a short time ago. Human need and ingenuity continue to spur their development and construction equipment rentals assure their ongoing importance in the societal infrastructure.
