CIMC Intermodal Equilink Co., Ltd. specializes in high-quality trailer accessories, with its core product series covering trailer landing gear and trailer rims. These two components are essential for the safe operation, stability, and efficiency of semi-trailers, playing a pivotal role in global logistics and transportation. We are committed to upgrading product quality and usage efficiency, creating reliable, durable, and cost-effective trailer parts that are trusted by customers worldwide.

Trailer Landing Gear: The Stable Support of Semi-Trailers

Trailer landing gear, commonly known as "support legs" or "auxiliary supports", is an integral part of semi-trailers. Its core function is to stably support the semi-trailer when it is separated from the tractor, ensuring safe loading, unloading, and parking operations.

Standard Specifications & Core Parameters

Our standard semi-trailer landing gear comes with industry-leading specifications to meet diverse operational needs:

• Common stroke: 480cm

• Standard height: 90cm

• Rated load: 28 tons

• Static load capacity: 80 tons

These parameters ensure the landing gear can withstand heavy loads and adapt to most semi-trailer models, providing reliable support in various scenarios.

Key Types of Trailer Landing Gear & Selection Guide

We offer two main types of trailer landing gear, each designed for specific working conditions to maximize operational efficiency:

1. Single-Action Trailer Landing Gear

• Structural Feature: Equipped with a gearbox on both sides (available in internal and external types), controlled by two independent rockers.

• Operation Mode: Can be raised and lowered independently, with two gears (high speed and low speed) for flexible operation.

￮ No-load operation: High or low speed can be used.

￮ Heavy-load operation: Must use low speed to ensure stability and avoid gear damage.

• Advantages: Strong adaptability, suitable for both flat and uneven ground, making it the most basic and widely used traditional landing gear.

• Suitability: Ideal for construction sites, rural roads, and other scenarios with uneven ground.

2. Coupled Trailer Landing Gear

• Structural Feature: Only the main leg is equipped with a gearbox; the main and auxiliary legs are connected by a rocker and connecting rod, enabling synchronous lifting and lowering.

• Operation Mode: Also equipped with high and low speed gears, an upgraded version of the traditional single-action landing gear.

• Advantages: Lifting efficiency is twice that of single-action landing gear, saving time and labor costs for frequent operations.

• Suitability: Only applicable to flat roads; when used on uneven ground, cushion blocks must be used to keep the support surface basically level.

Industry Trend: From Traditional Manufacturing to Intelligent Manufacturing

From the continuous upgrading of trailer landing gear, it is evident that the semi-trailer industry is undergoing a transformation from traditional manufacturing to "intelligent manufacturing". This transformation helps improve the automation and intelligence level of semi-trailers, further ensuring operational safety and efficiency. CIMC Equilink has been at the forefront of this trend, continuously optimizing product design and manufacturing processes to deliver high-performance, intelligent trailer accessories.

Trailer Rim: The Core Component of Trailer Wheels

Trailer rims, commonly known as "wheel rims", are key components that mount tires around the wheel hub. They directly determine the compatibility of tires, the stability of the vehicle, and the safety of high-speed driving. China’s rim specification codes are basically consistent with international standards, ensuring global interchangeability.

Rim Specification Standards

• Nominal width and diameter: Expressed in inches.

• Joint symbol: The middle symbol (* or -) indicates whether the rim is integral:

￮ Example 1: 4.50E*16 – Integral rim with a nominal width of 4.5 inches and rim code E.

￮ Example 2: 6.5-20 – Multi-piece flat-bottom wide rim with a nominal width of 6.5 inches and a nominal diameter of 20 inches.

• Importance of specification matching: The rim specification directly determines the type of tires that can be used, and incorrect matching will lead to safety hazards during operation.

Outstanding Features of CIMC Equilink Aluminum Alloy Trailer Rims

Our factory specializes in producing high-quality, cost-effective aluminum alloy trailer rims, which have significant advantages over traditional steel rims:

1. Lightweight Design: Aluminum rims are much lighter than steel rims, effectively reducing the vehicle’s tare weight and contributing significantly to fuel savings.

2. Excellent Heat Dissipation: Superior heat dissipation performance extends tire service life; some aluminum alloy rims can guide air flow to the brakes during rotation, further enhancing heat dissipation efficiency.

3. High Roundness: Ensures high wheel motion accuracy, making it suitable for high-speed driving and reducing vehicle vibration.

4. Good Energy Absorption: Absorbs vibration and noise from the road surface, improving the comfort of the vehicle during driving.

5. High Rigidity: Effectively reduces damage to the rim caused by road impacts, ensuring long-term durability.

6. Flexible Design: Less restricted by shape, can be customized into various styles according to customer requirements, meeting personalized needs.
