LANDNEO WZ38-28 Heavy-Duty Backhoe Loader | Reinforced Steel Chassis | 46.5KN Excavator Force | 8-Ton Industrial Earthmoving Machine | SHENTUI Structural Edition

LANDNEO WZ38-28 – Heavy Industrial Engineering for Zero Frame Fatigue

Tough digging conditions test the structural limits of construction machinery. The LANDNEO WZ38-28 utilizes thick-plate high-strength steel, robotic-welded box structures, and heavy pivot pins to resist frame torsional stress, fatigue cracking, and boom distortion under maximum hydraulic pressure.

Product Highlights

• Reinforced Box-Section Boom: Heavy-wall excavator arm and loader lift arms resist twisting forces during deep breakout operations.

• Heavy-Duty A-Frame Outriggers: Wide stance A-type stabilizer legs distribute high reactive digging forces safely to the ground, preventing chassis stress concentration.

• Heavy Load Rated Axles: Equipped with a 4-ton rated front steering drive axle and an 18.5-ton rated rear drive axle for handling extreme static and dynamic loads.

• High Hydraulic Operating Margin: Rated for 22MPa working pressure with burst-resistant hydraulic steel piping and high-grade flex hoses.

• Dual-Reduction Drivetrain: Double-reduction main drive and single-stage wheel hub reduction protect internal shafts from torsional shock loads.

 FAQ

Q1: How does the frame handle high torsional loads during offset excavation?
A: The machine is built with robotic box-welded steel plates and backed by wide A-frame outriggers that anchor the chassis and absorb torsional digging forces.

Q2: What is the breakout force rating for demanding digging?
A: The rear excavator delivers 46.5KN of bucket grab force and 31KN of dipper tearout force at 22MPa system pressure.

Q3: What are the load capacities of the drive axles?
A: The front drive steering axle is rated for 4 tons, and the rear axle is rated for 18.5 tons.

Q4: How does the final drive protect against sudden torque spikes?
A: The drivetrain uses a double-reduction main transmission combined with hub-mounted planetary final reducers to dissipate peak torque loads.

Q5: Are replacement hydraulic pins and bushings standardized?
A: Yes, all pivot points use standardized, heat-treated hardened steel pins with grease channels for long service life and straightforward replacement.
