How to Buy Used Excavator?

by John Craig Buy Used Machinery From Estec Japan

A digger also called a hydraulic excavator or excavator is a machine consisting of a wheeled or tracked undercarriage on which rests a pivoting turret which combines the driving position, the engine, the hydraulic systems and the arm.

The arm that roughly imitates the movements of a human arm allows the use of different tools, the most common is a bucket for digging the ground, but a shovel can also accept breakers, clamps, grapples, forks, demolition tools, etc. This versatility makes it an essential tool for earthworks on construction sites, but also in the handling of bulk products, demolition, mining and quarrying or logging.

Tips to Buy Used Excavator

There are two main families of excavators, wheeled excavators and crawler excavators, both of which have their advantages and disadvantages, and you will need to first determine which one is best for you.

You will then need to determine if you need a "standard" shovel or a particular configuration. There are not many morphological differences between different shovels, even from one manufacturer to another, a shovel is a versatile machine and it is often enough to change his tool according to the work to be done.

However, there are some configurations adapted to particular conditions, for example:

Demolition shovels whose arms have been lengthened to reach the top of the buildings with their demolition tools, their cab is usually protected from falling materials and can be tilted upwards to allow the operator to see where he stands.
Shovels without backswing that can rotate without exceeding the ground surface of the machine, allowing to work close to walls without the risk of touching them.
Spider excavators equipped with articulated "legs" to work on steep or difficult terrain.
Shovels called "multifunction" whose arm has additional joints to increase the range of possible movements and therefore the versatility of the machine.
We can also mention the rail/road versions intended to move on railway networks, amphibious models to work on water bodies, etc.

The main criterion of choice to buy used excavator from Estec Japan is its size and power. The size of the machine is characterized by its weight in running order (we speak of a shovel of 10 tons for example) The range of sizes available is very wide, of less than a ton for the smaller models with more than 100 tonnes for excavators used in open-pit mines.

You will need to choose a shovel adapted to your needs, a model too small may not meet the needs of the work to be done, a model too large may be too bulky and especially too expensive. If you are looking to Buy used excavator then visit Estec-trade and check our catalog.
