How can we ensure the quality of our excavator long arms
Material selection and supply chain management
The boom arm are constructed using high-quality, certified Shaogang Q355B and Q690D steel.
The hydraulic seamless pipe is sourced as per national standards, ensuring precision and seamless performance.
The pin used is made of 40MuCr alloy, while the high-pressure hose features a four-layer steel ring design.
The boom base incorporates a graphite alloy copper sleeve for enhanced durability and performance.
Freely Switch the Attachments You Need
The telescopic arm can freely choose three versatile attachments: a clamshell bucket, an orange peel grab, and a digging bucket. Let's delve into the description of each aspect:
Clamshell Bucket: The clamshell bucket consists of two hinged buckets that open and close like a clamshell. The arm's extending and contracting capabilities allow the operator to reach and gather materials from various distances. The clamshell bucket is primarily used for handling loose materials such as sand, gravel, and debris. Its dual-bucket design enables efficient scooping and lifting operations, providing enhanced productivity and flexibility on the job site.
Orange peel grab: The telescopic arm of the excavator can also be equipped with a lotus grab attachment. The lotus grab is a versatile tool for grasping and lifting objects. With the telescopic arm's extendable reach, the lotus grab enables the operator to securely grip objects of different sizes and shapes. This attachment is particularly useful when handling irregularly shaped items, logs, pipes and materials. The lotus grab's design ensures a firm grip, enhancing safety and efficiency during material handling operations.
Digging Bucket: In addition to the clamshell bucket and Orange peel grab, the excavator's telescopic arm can be fitted with a digging bucket. The digging bucket is a robust attachment specifically designed for excavation and digging tasks. The telescopic arm's extended reach enables the operator to dig deeper and reach areas that may be challenging to access with a standard arm. The digging bucket features rugged teeth or blades that efficiently penetrate the ground, making it ideal for various excavation projects such as trenching, foundation digging, and general earthmoving tasks. Its capacity and design contribute to faster digging cycles and increased productivity on construction sites.
