Lift Arm For Wheel Loader Spare Parts
Part name: swing arm
The excavator arm, also known as the swing arm, is composed of a stick mounting seat, a hydraulic cylinder mounting seat, a chassis mounting seat, side plates, upper and lower cover plates, curved plates, etc., which are used to connect the excavator stick to control the excavation and Loading action. It adopts a reinforced plate design, which can be called a reinforced arm. It is also manufactured with cutting-edge welding technology and meets Kato and Hyundai standards to ensure accurate installation dimensions. 100% ultrasonic flow detection to ensure the high reliability of the boom.
The lift arm includes an improved design that can extend the overall life of the assembly by at least 30%. Combined with a two-piece forged torque tube, added packaging plate and larger bucket pin, we can modify your existing arm or make new components for your machine.
- ★Improved ball cups. This design has improved weld detail between the arms and cups, reducing cracking around ball cup welds. In addition, an extra row of bolts was added to the top and bottom of the cup/cap to prevent bolt failure.
- ★Forged torque tube. Increases the quality of the component when compared to a casting.
- ★Two piece bell crank ear bushing. The two piece bushing is designed with a top hat; the bushing installs from both sides of the bell crank ear and prevents side to side motion of the bell crank.
Increase packaging thickness
Reduce the cracking of the top and bottom wrapping paper, wrapping paper welds and arms. This is achieved by reducing the stress range. Reduce the stress range by increasing the section modulus from thicker wrapping paper and moving the weld to a lower stress area.
Two piece forged torque tube
Eliminates welds from spool to cast bell crank ear. The life of the torque tube is increased with the use of forged material and by moving the weld area to a lower stress range.
Larger bucket pin and Toughmet bushings
The bucket pin size was increased, and Toughmet outer bushings are used to prevent cracking, increasing the lifespan.
