Engineering machinery leasing companies, infrastructure construction contractors and heavy equipment import and export enterprises need lowbed semi trailers with ultra-low platform height and super strong load-bearing capacity to transport excavators, bulldozers, loaders, road rollers and other high-center-of-gravity heavy construction machinery. Shandong Junchi’s full range of lowbed semi trailers cover 40-ton to 150-ton load specifications, including fixed gooseneck lowbeds and detachable gooseneck low loader trailers, solving the core pain points of heavy machinery transport such as high platform leading to height limit violations, insufficient load capacity and inconvenient machinery driving on and off.
The ultra-low concave beam platform structure is the core advantage of Junchi lowbed semi trailers. The main beam adopts concave design, lowering the platform height to 850mm, which can avoid highway height limit restrictions when transporting large excavators and road rollers, greatly reducing the detour costs caused by height limits during cross-city machinery transportation. The platform bottom plate uses thickened wear-resistant manganese steel, with multiple rows of heavy-duty binding rings reserved to fix the caterpillar tracks of construction machinery, preventing machinery sliding during long-distance highway driving and sharp turns.
Two gooseneck structures are available for customers to choose: fixed gooseneck lowbed trailers with lower purchase prices, suitable for regular medium-sized excavator transportation; detachable gooseneck low loader trailers can completely separate the front gooseneck from the platform, allowing heavy machinery to drive directly from the front of the platform without rear loading ramps, especially suitable for super-large tonnage road rollers and mining excavators transportation. The rear loading ramps adopt hydraulic lifting design, with thickened anti-slip patterns on the ramp surface, and can bear the weight of full-load construction machinery to drive up and down smoothly.
The chassis load-bearing system is reinforced according to super heavy-load standards. Super large tonnage lowbed semi trailers adopt multi-line heavy-duty axles, with optional hydraulic suspension that can adjust the platform height to adapt to uneven road surfaces; the multi-group thickened main beams can evenly disperse 150-ton heavy machinery pressure without frame bending and deformation. All lowbed semi trailers undergo full-load static pressure tests and highway simulation vibration tests before leaving the factory, ensuring the structural stability of the frame under long-term heavy machinery load.
Customization services cover platform length, number of axles, gooseneck type, hydraulic ramp configuration, tire specifications and side guard anti-collision plates. Shandong Junchi provides complete heavy equipment transport vehicle export certification documents to support customs clearance of construction machinery transport fleets in Africa, Southeast Asia and South American infrastructure construction markets. An engineering machinery leasing group in Tanzania purchased 25 units of Junchi detachable gooseneck lowbed semi trailers, and the fleet manager reported that the height limit detour rate of machinery transportation decreased by 80%, and the loading time of each excavator was cut by more than half, greatly improving the fleet’s daily machinery delivery volume. Designed for super heavy construction machinery transport scenarios, Shandong Junchi lowbed semi trailers deliver ultra-low platform, super load-bearing and convenient loading performance for global engineering transport fleets.
