Introduction
Are you keen on understanding the structural features of Chinese telescopic trailers? Then you’ve come to the right place. Chinese telescopic trailers have emerged as a preferred choice due to their structural integrity, flexibility, and cost-effectiveness. But these trailers are built to handle the size and weight of wind blades.
Core Structural Components
Gooseneck: An Essential Trait
Chinese telescopic trailers for wind blade transportation have two variations: the Cranked Gooseneck and the Straight Gooseneck. The straight version features a front platform that aligns with the rear platform in height. However, the cranked version boasts a crank behind the front platform, allowing for a lower platform height at the rear.
Hydraulic gooseneck presents an additional advantage, allowing drivers to adjust the trailer’s height to suit different heights of the fifth wheel on tractors. Furthermore, when the truck steers, the hydraulic gooseneck signals the rear axles to steer, enabling tighter radius turns and enhanced maneuverability on curvy roads.
Chassis & Material: Ensuring Stability and Durability
The chassis forms the foundation of the telescopic trailer, engineered to withstand the weight and dimensions of wind blades. It is built from tough-as-nails steel like HG60 or Q550 and promises to stay sturdy and steady while hauling. However, it is worth noting that some suppliers may utilize lower-quality steel, like Q456 or Q345, to reduce production costs and offer lower prices. Consequently, this compromise may result in the trailer’s telescopic beam sagging, significantly impacting its lifespan.
Extension Mechanism: Adapting to Varied Blade Sizes
The heart of the telescopic trailer lies in its extension mechanism, which accommodates different blade sizes through a combination of hydraulic and mechanical systems. This system smoothly extends and pulls back, effortlessly adapting to the unique sizes of wind turbine blades.
Axles and Tires: A Matter of Compliance and Load Capacity
The number of axles required is dictated mainly by the regulations imposed in different countries. In addition to the existing 3-axle, 4-axle, and 5-axle telescopic wind blade trailers, there are also options with 6, 9, and 10-axle for flatbed trailers, low-loaders, and custom-built configurations. To haul those massive wind blades, you’ve got options like 3, 4, 5, 6, 9, and 10-axle flatbed trailers and lowboys that let you pick the right combo of load capacity and wheelbase to follow local regs, while tires from 275 to 12R handle your platform height and weight needs.
Regarding tires, the choice depends on the load and platform height requirements. You’ve got options galore with sizes like 275/80R22.5, 215/75R17.5, 235/75R17.5, 11R22.5 and 12R22.5 to match your specific needs.
Loading Platform: Ensuring Secure Blade Transit
The loading platform, responsible for securing wind blades, typically spans around 20 meters in length. The trailer has particular parts to keep the blades steady and lower risks while shipping them.
Kingpin and Landing Gears: Connecting and Stabilizing the Trailer
The kingpin, available in 3.5-inch or 2-inch variants, is crucial for connecting the trailer to the tractor unit. Landing gears, mechanical and hydraulic, serve this purpose efficiently and play a vital role in keeping the trailer steady when it’s not hitched to the tractor unit.
Advanced Features
Steering Systems
Steering systems play a critical role in wind blade transport by offering pinpoint control and navigation, even in tight spaces and rough terrain.
With a top-notch steering system, you can precisely steer through narrow spaces and tricky terrains to ensure the safe haul of wind blades. Three main steering systems are prominent in Chinese telescopic trailers designed for wind blades:
- Hydraulic Turntable Steering:
- With a big turning angle (25° to 45°), this steering system really improves the nimbleness of telescopic wind blade trailers.
- It curbs the need for frequent maintenance and limits tire wear, perfectly marrying productivity with cost-effectiveness.
- Depending on axle loads and transportation needs, one can choose between mechanical spring and air suspensions. The latter boasts a raise-and-lower platform function.
- Hydraulic Steering Axles:
- Hydraulic steering axles facilitate smooth movement around tight corners with their generous steering angle.
- As the truck turns, the gooseneck sends a signal to the rear steering axles, coordinating their movement. But these axles also help the trailer turn better, wear out the tires less, and last longer.
- In addition, they’re designed with the handy ability to tweak the platform’s height, adding a touch of ease to the whole deal.
- Hydraulic Bogies:
- Hydraulic bogies, or hydraulic suspension, are commonly employed in multi-axle modular trailers.
- With an impressive steering angle of up to +/-55°, these bogies minimize the turning radius and enhance the trailer’s agility. Moreover, they allow for height adjustment of the cargo platform.
- However, it must be noted that hydraulic suspension is more expensive than turntable steering and hydraulic steering axles. The latter options are more economically viable unless a lower platform height is mandatory.
Suspension Systems
Like those in multi-axle modular trailers, a hydraulic suspension system delivers better agility and adjustable platform height but can be pricier than other steering alternatives. The telescopic suspension absorbs shocks to protect the blades during transport.
The job of the suspension system is pretty important; it soaks up all those bumps and shakes during transport, keeping wind blades safe from any possible harm. Picking the right suspension for your wind-blade trailer is all about what it can carry, how local traffic laws roll, and how much cash you’re willing to drop. Standard options available for telescopic wind blade trailers include leaf spring mechanical suspension, air ride suspension, and hydraulic suspension. HIPOTRUK telescopic Wind Blade Trailers mainly adopt air suspension due to its affordability, durability, ease of maintenance, and exceptional capability to withstand rough road conditions.
Braking System
Safety is paramount given the substantial load and critical nature of wind blade transportation. It is advisable to opt for trailers equipped with superior safety features such as WABCO emergency relay valves and anti-lock braking systems (ABS). These safety features significantly reduce the chance of skidding and ensure that the wind blades stay put during transport.
