Technical Questions
What is a lowbed semi-trailer?
A lowbed semi-trailer (also called a low loader) is a specialized heavy-duty trailer with a low deck height, designed to transport tall, heavy, and oversized equipment such as excavators, bulldozers, cranes, generators, and other construction or industrial machinery. The low platform height allows taller loads while remaining within road height restrictions.
What industries use lowbed trailers?
Lowbed trailers are essential in construction, mining, oil & gas, wind energy, military logistics, agriculture, and heavy industrial sectors. They transport excavators, bulldozers, mobile cranes, generators, transformers, wind turbine components, armoured vehicles, and other oversized equipment.
What are the advantages of a lowbed trailer over a flatbed?
Key advantages include: lower deck height (850mm vs 1,300mm+) allowing taller loads within legal height limits, hydraulic rear ramp for self-loading tracked/wheeled machinery, higher payload capacity (60-100 tonnes), air suspension for load protection, and reinforced structure designed specifically for concentrated heavy loads.
What axle configurations are available?
Femmerr lowbed trailers are available in 3-axle (60t payload), 4-axle (75t payload), and 5-axle (100t payload) configurations. All feature BPW/SAF brand axles with full air suspension, lifting function, and WABCO EBS electronic braking with ABS.
What is the platform height and why does it matter?
The platform height is approximately 850mm from ground level. This low height is critical because it maximizes the usable height for cargo while keeping within road transport height regulations (typically 4.0m to 4.2m depending on country). This means you can transport taller machinery without requiring special permits.
How does the hydraulic ramp system work?
The hydraulic rear ramp is operated via a control panel or remote control. It lowers to create a gradual incline for tracked and wheeled machinery to drive onto the platform. The ramp features non-slip surface treatment and is rated for the full payload capacity of the trailer.
What is the king pin load capacity?
King pin load capacity ranges from 20 tonnes (3-axle) to 30 tonnes (5-axle). We use JOST brand 2" or 3.5" king pins, bolted type, manufactured to SAE J700 standards for reliable coupling with standard fifth wheel systems.
What are the tire specifications?
The trailer uses 245/70 R17.5 or 235/75 R17.5 heavy-duty tires on steel disc rims. Tire quantity varies by axle configuration: 12 pcs (3-axle), 16 pcs (4-axle), or 20 pcs (5-axle). A spare tire is included as standard.
Material & Engineering FAQs
What steel grade is used for the chassis?
The main frame is constructed from S700MC high-strength structural steel with a minimum yield strength of 700 MPa. The deck surface uses Hardox 450 wear plates for resistance against abrasion from tracked machinery. Gooseneck and critical stress points feature additional reinforcement plates.
What material is used for the platform deck?
The platform deck combines S700MC structural steel for the main beams with Hardox 450 anti-wear steel plates on the surface. This provides both structural strength and abrasion resistance from heavy tracked machinery driving over the deck surface.
What coating system protects the trailer?
A 4-layer industrial coating system: (1) Shot blasting to SA 2.5 standard for optimal surface preparation, (2) Zinc-rich primer for corrosion protection, (3) Epoxy intermediate coat, (4) Polyurethane topcoat in customer-specified RAL colour for UV resistance and durability.
What brake system is installed?
All models feature WABCO or Knorr-Bremse EBS (Electronic Braking System) with ABS anti-lock functionality. Disc brakes are fitted on all axles with automatic slack adjusters. Emergency and parking brake chambers are included on every axle for maximum safety.
What suspension system is used?
Full air suspension with ride height adjustment is standard on all models. This allows the platform to be raised or lowered for loading operations and to match different tractor fifth-wheel heights. 4-axle and 5-axle models include pneumatic lifting axles to reduce tire wear on unladen return trips.
