Large-Size SUV Retractable Steps

-- Steady & Reliable Manufacturer --

Enhanced Access Solutions for Full-Size SUVs

This line is specifically designed for the dimensional and weight requirements of full-size, three-row SUVs (e.g., Chevrolet Suburban, Cadillac Escalade, Toyota Sequoia). The system incorporates an extended step surface area and utilizes multiple mounting points (typically three or four per side) to ensure stability and load distribution across the longer wheelbase. A reinforced, dual-motor system is standard, delivering the necessary torque to deploy the larger and heavier step boards reliably. The retraction mechanism is engineered for a smooth, damped motion to manage the inertia of the larger components, ensuring operational longevity and structural silence.

BOHAI: Scalability and Structural Integrity

At BOHAI Auto Technology, we combine advanced manufacturing precision with structural engineering expertise to meet the demands of large vehicle platforms. Our facility’s intelligent automatic CNC machining centers ensure the exact tolerance required for the extended bracket systems of full-size SUVs. This focus on structural integrity is central to our quality policy, guaranteeing that our retractable steps provide a safe, stable platform. Our internal ERP system allows for precise tracking of all materials and components utilized in these complex, heavy-duty assemblies.

Applications for Extended Vehicle Platforms

Full-Size Family Vehicles: Installation on large vehicles where the height difference makes entry/exit difficult for children and elderly passengers.
Towing & Payload: Provides easier access to roof racks, cargo carriers, and the forward area of trailers connected to the vehicle.
Limousine/Executive Transport: Enhancing the luxury and convenience aspect of customized large SUVs used for corporate and VIP transport.

Frequently Asked Questions (FAQ)

Q: Are the steps rated for use by multiple people simultaneously?
A: While designed with a significant safety margin, the Maximum Static Load Capacity applies to the total load at any given moment. Simultaneous use by two adults is generally within the safety rating, but the product is primarily designed for sequential entry/exit.

Q: How does the system manage power if the vehicle is frequently started and stopped?
A: The electronic control module (ECM) incorporates logic to prevent excessive cycling during brief stops (e.g., traffic lights) and features low-voltage cutoff protection to prevent draining the vehicle's main battery.

Q: Do these steps interfere with the factory ground effects or mud flaps?
A: Interference is rare for the designated vehicle models. Our design process includes clearance mapping to ensure the step deploys outside the envelope of most factory-installed accessories. Specific fitment notes are provided.

Engineering Distinctions and Benefits

Multi-Point Load Distribution: The use of three or more mounting points per step ensures stability and disperses the stepping load effectively across the vehicle's frame, reducing localized stress.
Extended Step Surface: The increased width and length of the step platform accommodate larger footwear and provide a more secure feeling of stability for passengers of all sizes.
Quiet Operation: Utilizing high-tolerance, self-lubricating nylon bearings and precision-machined gears minimizes operational noise, aligning with the quiet cabin experience of luxury SUVs.
Integrated Lighting Option: Select models incorporate integrated LED strip lighting along the board's edge, which activates upon deployment, enhancing safety in low-light conditions.

Manufacturing Capabilities and Services

We offer specialized logistical support for large-volume orders of these extended steps, including optimized packaging to minimize shipping damage for long, heavy components. Customization focuses on: specific aesthetic finishes (e.g., chrome trim, polished aluminum), bespoke lighting integration, and bracket engineering for armored or specialty-modified full-size SUVs. Our quality assurance process includes non-destructive testing (NDT) of critical load-bearing welds on bracket assemblies to verify their structural integrity.

Material Composition and Selection

Brackets and Hinge Assemblies: High-carbon steel with enhanced thickness and gusseting to manage the stress from the vehicle's mass and the leverage of the extended step.
Step Surface: Aluminum T-slot extrusions that allow for precise, continuous attachment of the non-slip surface and maximize structural stiffness over the extended length.
Damping Components: Specialized thermoplastic elastomers (TPE) or rubber pads are used at contact points to absorb minor vibrations and further reduce operational noise.
