Caterpillar Bucket Tooth 505-4113 For CAT349 Excavator

In hard rock crushing operations in granite mines, Caterpillar bucket tooth, thanks to their high-manganese steel construction and bionic tooth profile design, demonstrate exceptional impact resistance. When cutting into granite with a hardness of up to 120 MPa, the curved tooth surface disperses contact stress, preventing localized stress concentration and tip fracture. The thickened tooth root can withstand excavation impact forces of 300 kN, maintaining stable operating efficiency even under repeated impacts.

The narrow pitch design and smooth tooth surface of the Caterpillar 349 bucket teeth play a key role in soft soil operations during rice paddy field renovation. Soft soil has a high moisture content and strong adhesion, which can easily cause soil to stick to conventional bucket teeth. However, the nano-coating on the Caterpillar 349 bucket teeth reduces soil adhesion by 40%. Only a thin layer of soil remains on the tooth surface during each lift, eliminating the need for cleaning.

At the same time, the narrow tooth pitch design of the Caterpillar bucket tooth can reduce cutting resistance. In soft soil operations with a digging depth of up to 2.5m, the digging resistance is reduced by 25% compared with ordinary bucket teeth. Combined with the equipment's hydraulic system, the single-cycle operation time is shortened to 15 seconds, and 240 cycles can be completed per hour. The operating efficiency is 30% higher than that of traditional bucket teeth, which perfectly adapts to the efficient earthwork handling needs in soft soil scenarios.

In construction waste disposal scenarios, the Caterpillar 349 bucket teeth' wide tooth profile and high-strength structure are ideal for excavating and crushing mixed materials such as concrete blocks and rebar. The wide tooth profile increases the contact area with the construction waste, preventing deformation caused by excessive force on a single tooth. The special quenching process on the tooth tips enhances cutting power, enabling easy penetration and crushing of reinforced concrete blocks as small as 10 cm in diameter.

In construction waste sorting operations, Caterpillar bucket tooth can be used in conjunction with hydraulic grabs to precisely grasp and transport materials, separating recyclable materials such as concrete blocks and bricks from domestic waste with a separation efficiency exceeding 85%. Furthermore, the teeth' anti-adhesion coating reduces the accumulation of concrete debris on the tooth surfaces, requiring only one cleaning per hour, ensuring continuous operation and perfectly adapting to the complex operational demands of construction waste handling.
