Specifications vary by manufacturer (e.g., CIMC, XCMG, Schmitz Cargobull) and custom requirements (e.g., cold-region hydraulic oil, extra-thick bucket steel for mining waste). For construction-site use, confirm local road load limits and site access width before finalizing configurations. Refer to the manufacturer's technical datasheet for precise parameters.

Product Brief and Product Content Introduction

Product Brief

The Side-loading Tipper Semi-trailer (Model: SLT-S350) is a high-efficiency, heavy-duty transport solution engineered for construction sites, mines, and building material yards. It integrates two core functions-side-loading (for narrow-space operations) and hydraulic tipping (for automatic unloading)-to streamline the handling of bulk materials (sand, gravel, construction debris) and large components (steel beams, precast concrete blocks). With a 35-metric-ton rated payload (3-axle configuration), 7-meter side-loading opening, and 50° maximum tipping angle, this semi-trailer excels in space-constrained areas where traditional top-loading trailers struggle. It complies with international standards (ECE R13 for braking, ISO 1496-1 for load safety) and is compatible with mainstream tractors (Sinotruk, FAW, Volvo) via 50#/90# kingpins, making it a reliable choice for global clients seeking to boost loading/unloading efficiency and reduce labor costs.

Product Content Introduction

Side-loading Tipper Semi-trailer (Model: SLT-S350) features a flexible side-loading system tailored for narrow-site operations. Its 7-meter single-side opening (height 1.5 meters) aligns with the working range of most side loaders (bucket width 1.8–3.0 meters), allowing easy loading of bulk materials or large components without requiring wide turning space. The side panels are driven by a hydraulic system (16 MPa working pressure), opening/closing in 15 seconds via tractor cab controls or an optional wireless remote (50-meter range)-operators can stand clear of moving cargo, enhancing safety. Guide rails (400 mm height) along the opening prevent material spillage during loading, reducing waste and cleanup time.

Side-loading Tipper Semi-trailer (Model: SLT-S350) delivers powerful hydraulic tipping performance for fast, labor-free unloading. Equipped with three 200-mm bore hydraulic cylinders (stroke 2800 mm) and a gear pump (20 MPa pressure), it achieves a 50° maximum tipping angle-sufficient to empty all bulk materials (e.g., gravel, construction waste) in 60 seconds. A built-in overload protection valve cuts off lifting if the load exceeds 38 metric tons (120% of rated payload), preventing cylinder damage. A check valve locks the cargo body in place if hydraulic pressure is lost, avoiding accidental tipping during transport.

Side-loading Tipper Semi-trailer (Model: SLT-S350) boasts a durable structure designed for heavy-duty site use. The main frame is constructed from Q345B high-strength steel (300×150×8×12 mm section size) with crossbeams spaced 600 mm apart, ensuring even load distribution and resistance to bending. The U-shaped cargo bucket (length 8.5 meters, width 2.5 meters) uses 8-mm wear-resistant manganese steel (65Mn)-abrasion-resistant against sharp gravel or construction debris, extending the bucket's service life to 5+ years. The entire frame undergoes hot-dip galvanizing (Zn coating ≥85 μm), protecting against rust from mud or rain in construction sites.

Side-loading Tipper Semi-trailer (Model: SLT-S350) offers road-compliant dimensions and balanced load capacity. Its overall length is 13.7 meters (legal in most regions), width 2.55 meters, and ground clearance 320 mm-navigating uneven site roads without scraping. The 3-axle configuration (equivalent to BPW heavy-duty axles) supports a 35-metric-ton rated payload, with each axle bearing ≤11.7 tons (complying with road load limits). The 6.8+1.3-meter axle spacing ensures stable driving even when fully loaded, reducing tire wear during long hauls from quarries to construction sites.

Side-loading Tipper Semi-trailer (Model: SLT-S350) ensures stable driving and safety with a robust suspension and braking system. It comes standard with reinforced leaf spring suspension (14 leaves per axle, 60Si2Mn steel)-absorbing vibrations from rough site terrain to protect the cargo body and reduce driver fatigue. The braking system includes 420-mm diameter pneumatic drum brakes (180-mm width) and ECE R13-certified ABS, preventing wheel lock during emergency stops on wet or muddy roads. A spring-loaded parking brake secures the trailer firmly when parked at sloped construction sites.

Side-loading Tipper Semi-trailer (Model: SLT-S350) prioritizes user safety and operational convenience with thoughtful design details. Visual warning lights (red flashing) are mounted on the side panels-alerting nearby workers when loading/unloading to avoid collisions. Anti-roll side rails (10-mm thickness) reinforce the frame, reducing rollover risk when tipping on uneven ground. Two electric support legs (20-ton capacity each) replace manual cranking, allowing quick leveling of the trailer when disconnected from the tractor-saving setup time during loading shifts.

Side-loading Tipper Semi-trailer (Model: SLT-S350) supports customization to meet diverse client needs, enhancing its versatility. For cold regions, clients can opt for low-temperature hydraulic oil (-25°C viscosity) to prevent system freezing. For mining use, an extra-thick (10-mm) bucket steel upgrade is available for increased abrasion resistance. Double-side loading openings (instead of single-side) are an option for sites requiring multi-directional loading. The manufacturer provides a 1-year warranty for the hydraulic system and frame, plus free replacement of vulnerable parts (e.g., side panel seals) within 6 months-lowering post-purchase maintenance costs for clients.
