Application Scenarios

It is widely used for supporting and fixing hydraulic valve blocks, pipeline assemblies and auxiliary accessories of wheel loaders, suitable for earthwork, quarry and sand loading construction sites.

• Manufactured according to OEM specifications, hole spacing and outline size fully match the original assembly, install directly without cutting or welding modification, saving replacement time.
• Q355 steel plate with high rigidity and excellent toughness, not easy to deform under long-term vibration impact and component weight load.
• Stress relief annealing treatment reduces cracking risk caused by residual stress under alternating load, improving long-term reliability.
• Reasonable hole position layout, convenient for assembly and later inspection and maintenance, easy to align during installation.
• Stable welding quality, weld seams inspected one by one, high structural reliability, no welding defects such as slag inclusion.
• Double-layer anti-rust coating, strong adhesion, good anti-corrosion effect in muddy and dusty environment, slow aging rate.

FAQ 

Q1: Can this support plate be used to support components exceeding the designed load?
A1: No. Its structural strength and design bearing capacity are fixed. Overload will cause bending deformation or even fracture, which brings hidden dangers to the hydraulic system and may trigger unexpected downtime.

Q2: What faults will occur if the support plate is deformed or cracked?
A2: Deformation or cracks will make the supported components lose stable support, cause pipeline deflection and abnormal pulling force, easily trigger oil leakage and component damage during heavy-load operation.

Q3: What preparations should be done before installing the new support plate?
A3: Clean the mounting surface, remove mud and rust; align the hole position accurately, tighten the bolts evenly step by step to avoid uneven stress and local plate bending.

Q4: Can cracked support plate be welded for reuse?
A4: It is not recommended. Welding will generate new thermal stress, and secondary cracking is easy under vibration impact, it is safer to replace a new plate to avoid sudden failure.

Q5: Is there a fixed installation direction for this support plate?
A5: This support plate has a specific direction for load bearing. Compare it with the old part before installation to prevent wrong assembly and uneven force distribution.

Q6: What will happen if the fastening bolts are over-tightened?
A6: Excessive torque will bend the plate locally, change the supporting plane and make the connected pipelines and accessories bear abnormal stress and tensile load.
