Application Scenarios

It is widely used for installing and fixing limit switches and travel switches 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 and avoidance groove 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 switch bracket be used to install switches heavier than the designed load?
A1: No. Its structural strength and design bearing capacity are fixed. Overload will cause bending deformation or even fracture, resulting in unstable switch signal and potential safety hazards, and may trigger misoperation of the loader control system.

Q2: What faults will occur if the switch bracket is deformed or cracked?
A2: Deformation or cracks will make the switch lose stable support, lead to displacement of the contact position, easily trigger false signals or no signal feedback during operation, which will affect the normal judgment of the limit state of the working mechanism.

Q3: What preparations should be done before installing the new switch bracket?
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; check whether the sealing gasket and insulating washer of the switch are intact before assembly.

Q4: Can cracked switch bracket 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 and unexpected shutdown of the loader during operation.

Q5: Is there a fixed installation direction for this switch bracket?
A5: This bracket has a specific orientation for limiting and avoiding interference. Compare it with the old part before installation to prevent wrong assembly and signal failure, and avoid collision between the switch and surrounding structural parts.

Q6: How to maintain the switch bracket in daily use?
A6: Regularly check for cracks, paint peeling and bolt looseness; clean the dirt on the bracket surface, touch up paint timely when rust appears to slow down corrosion; check the fastening state of the switch at the same time during each maintenance.
