A 375 excavator (also called a full-slew excavatoror hydraulic excavator with 360° rotation) is a heavy-duty earthmoving machine—typically crawler (tracked) or wheeled—whose upper structure (cab, engine, boom & arm) is mounted on a slewing ring that permits continuous, unrestricted 360-degree rotation relative to the stationary undercarriage.
Main Components:
Undercarriage / Underframe – Track frame or wheel axles providing traction and stability.
Slewing Ring (Turntable Bearing) – Allows full-circle rotation of the house.
House / Superstructure – Houses the operator's cab, counterweight, hydraulic pump, and engine.
Working Attachment – Boom, arm (stick), and bucket; interchangeable with hydraulic breakers, augers, grapples, etc. via a quick-coupler.
Hydraulic System – Variable-displacement pumps delivering high-pressure oil to drive cylinders and travel/revolve motors.
Unlike a backhoe loader, which has a limited ~200° rear-arm swing and requires frequent repositioning, a 360 excavator can dig, swing, and dump in any direction without moving its tracks/wheels—maximizing productivity in confined urban sites, trenching, and large-scale earthworks
