Semi trailers are complex machines made up of numerous components that work together to transport goods safely and efficiently. Understanding these essential semi trailer parts, their maintenance requirements, and replacement processes is crucial for truckers and fleet managers. Here are the top 10 common parts of semi trailers, how they are maintained or replaced, and why LUEN stands out as your trusted provider for semi trailer components and services:
LUEN Trailer Axle
The trailer axle is the foundation of your semi truck trailer parts system, transferring load from the frame to the wheels while maintaining proper alignment. Regular bearing checks, lubrication, and alignment inspections are essential to prevent failures. When bearings wear out or axles need replacement due to misalignment, LUEN provides high-quality trailer axles and expert installation services to keep your fleet operational.
LUEN German Type Air Suspension
Suspension systems, consisting of leaf springs, shock absorbers, and airbags, provide stability and smooth rides for your trailer. These components naturally wear over time, showing signs like sagging, cracks, or leaks. When suspension parts fail or show excessive wear, LUEN offers premium replacement components and skilled technicians for suspension repairs, ensuring your trailer maintains optimal ride quality and load capacity.
Tires are perhaps the most critical component of any semi trailer. Regular inspections for tread depth, proper inflation, and wear patterns are vital for safety and efficiency. When replacement becomes necessary due to wear and tear or damage, LUEN provides a wide selection of quality tires suited for various road conditions and operational needs.
Brake systems, including brake pads, drums, and air brake chambers, are essential for safety and compliance. Routine inspections every 3,000 miles and timely replacements of worn brake components ensure optimal stopping performance. LUEN offers complete brake system parts and expert maintenance services to keep your trailers safe and road-ready.
Properly functioning lights and electrical systems are crucial for safety, visibility, and regulatory compliance. Faulty bulbs, corroded connectors, or damaged wiring should be addressed immediately to prevent accidents and violations. LUEN provides a comprehensive range of lighting and electrical components along with professional repair services to keep your trailer compliant.
The trailer floor endures constant stress from heavy loads and can develop cracks, rot, or structural damage over time. Whether made of wood, aluminum, or composite materials, damaged flooring compromises cargo security and trailer integrity. LUEN offers durable flooring materials and skilled installation services to restore your trailer's structural strength.
LUEN Fifth Wheel And KingPin
Fifth wheel couplings and kingpins are integral for connecting the trailer to the tractor securely. Regular lubrication and inspections prevent wear and ensure safe coupling. When these truck trailer parts show excessive play or damage, LUEN provides high-quality coupling components and maintenance services to maintain connection reliability.
The trailer's access points need to function smoothly for efficient loading operations. Damaged tracks, broken springs, or worn seals can disrupt operations and compromise cargo security. LUEN offers replacement doors, seals, and hardware along with skilled technicians for repairs to ensure seamless access to your cargo area.
LUEN Landing Gear
Landing gear enables the trailer to stand independently when detached from the tractor. Proper maintenance and timely replacement of worn gears, bent legs, or damaged cranks prevent operational disruptions at loading docks. LUEN supplies reliable landing gear assemblies and offers professional installation services to keep your drop-and-hook operations running smoothly.
Load securement equipment like straps, chains, and winches require regular inspection and replacement when worn or damaged. These parts of a semi truck trailer are critical for preventing cargo shifts during transport. LUEN offers a variety of cargo control accessories to ensure safe and secure transportation of goods.
Rear impact guards, also known as underride guards, are crucial safety features that prevent vehicles from sliding beneath the trailer during collisions. Regular inspections for damage or corrosion are necessary to maintain their protective function. LUEN provides compliant rear impact guards and installation services to enhance trailer safety and meet regulatory requirements.
