Boom & Arm We are specializing in the production of various kinds of standard booms, arms, and extension jibs for construction machinery. The specifiPCions and types can meet the requirements of over 90 kinds of excavators such as KOMATSU, KOBELCO, HITACHI, KATO, SUMITOMO, PC, HYUNDAI, DAEWOO, etc. Considerable improvement has been made with reasonable selection of materials and thickness after analysis of stress concentration part through FEM with the help of CAD system. The inside buffer plate is to support tensile load, which prolongs the service life of excavators. Ultrasound wave inspection is applied to check faultywelding points during the inspection period of assembly line. In order to further confirm the machine reliability, extensive jobsite operating trials have been conducted. We also can design various kinds of extension jibs according to customers requirements. There are two kinds of extension jibs: two-segment type and three-segment type. Two-segment type is mainly applied in the transit of building materials like earth, sand, and concrete, the slope maintenance of expressways, and the dredging of watercourses, etc. Three-segment type is mainly applied in demolishing high-rises.

Product Advantages

1. Material:
1) Entire jaw structure is manufactured of quenched and tempered Q690 High Strength alloy steel, 130,000-psi min. yield 360-440BHN.
2) The tine tips are 175,000-psi min. yield 450-550 BHN. Chromium plating.

2.Motor:
1) Motor drive adopts the design of symmetrical double support,strong shcok resistance, avoiding axle breakage and oil leakage.
2) Pedestal adopts sealed type design, better protect the rotary drive.
3) Output Torque:4 kN.m-8.5kN.m(6272lbf.ft)
Holding Torque 38kN.m-105kN.m(78000lbf.ft)
Moment Torque 26kN.m-203kN.m(150,000lbf.ft)

3. Strengths:
1) Sealed type rotary drive solve the oil leakage problem, only required light greasing(80g of grease) once 6 months(unlike most
of the product on the market needed greasing everyday) and better protect the product.
2) Motor drive adopted symetrical double support design, reducing the bearing load and extend service life.
3) The jaw structure is manufactured of Q690 High Strength Alloy Steel, lighter weight with twice of the strength comparing with
Q345(normally used on the market)
