- working body – bucket, rotor;
- drive.
The undercarriage is the basis of the machine, on which the other elements and the operator’s cabin are attached.
Excavator is a machine designed to perform heavy work, so it must be reliable, characterised by high performance.
Japanese excavators have gained recognition and trust. Earthmoving equipment is manufactured using the latest technologies, which allows to obtain highly efficient and productive equipment.In companies engaged in the supply of special equipment delivery from Japan, for example here https://eurasiantrade.co.jp/equipment/en, you can buy excavators of well-known brands and get professional advice.
Main characteristics
The main characteristics of earthmoving machines include bucket volume, company depth, work speed, curb weight.

Selection criteria
Buying an excavator is not an easy task. The optimal option, suitable for specific tasks, is selected according to several parameters.
The following criteria are taken into account:
- Productivity: according to this parameter, the excavator should correspond to the volume of work, for example, to ensure the loading of 1000 tonnes of hard rock in one shift.
- Functionality: the technique of cyclic action is equipped with a bucket, so the intake and movement of soil performs alternately; continuous models can carry out several functions at once.
- Boom length, which is selected depending on the distance of load movement.
- The possibility of attaching several attachments.
When buying customized special equipment from Japan, the company’s specialists help to choose the option that meets the objectives.
For a small amount of work will be enough mini-model. For medium volume it is better to choose a backhoe-loader; for large volume – a full-turn machine.
