Hydraulic Cylinders for Excavators
Toleng manufactures high-performance hydraulic cylinders for excavators used in construction, mining and earthmoving applications.
Our OEM excavator cylinders are engineered for high loads, harsh environments and long service life, providing reliable performance for boom, arm and bucket operations.
What Hydraulic Cylinders Are Used in Excavators?
Hydraulic cylinders for excavators are heavy-duty actuators that convert hydraulic pressure into linear force to control machine movements. Excavators typically use hydraulic cylinders for the boom, arm and bucket functions, allowing operators to perform digging, lifting and loading operations.
- Boom Cylinder — controls the up/down movement of the boom
- Arm Cylinder — controls the in/out movement of the arm
- Bucket Cylinder — controls the digging and dumping action of the bucket
