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)
