Full-Size SUV Electric Steps

-- Steady & Reliable Manufacturer --

Technical Overview

Electric steps designed for the full-size SUV segment feature a synchronized dual-motor actuation system per side, ensuring the extended-length platform deploys and retracts with uniform force and zero torsional flex across the span. The mechanism utilizes a precision-machined aluminum linkage paired with sealed, low-friction bearings for a subdued operational sound signature, essential for premium vehicles. The system incorporates redundant safety sensors that constantly monitor current draw and position, providing instant obstacle detection and soft-stop functionality.

Structural integrity is maintained through direct bolt-on brackets engineered to interface with the vehicle's primary frame or reinforced unibody structure, accommodating static load requirements up to 350 kg.

Introduction

Full-size SUVs demand access solutions that match their scale, power, and luxury. These electric steps provide a stable, automated platform, merging necessary utility with the vehicle's inherent design elegance. They deploy smoothly for seamless access and retract flush when not in use, preserving ground clearance and aesthetics.

Bohai Automotive Technology Co., Ltd. (BHTC) established in Huzhou, Zhejiang, specializes in large-scale SUV accessories. Our strategic location near key industrial hubs supports large-volume production and allows us to focus on engineering systems that integrate advanced electronics with robust, precision-built mechanical assemblies.

Applications

Luxury Transport Vehicles: Used for full-size models like the Cadillac Escalade, Lincoln Navigator, and large European SUVs where passenger safety and comfort are priorities.
High-Ride Vehicles: Necessary accessory for taller or suspension-lifted SUVs to provide a safe, ergonomic stepping height.
Commercial Fleets: Ideal for executive and airport shuttle services that require high-cycle durability and consistent performance.
Global Export Markets: Primary offering for markets (e.g., North America, Middle East) where full-size SUV sales are dominant.

Common Questions

Q: How is the stability of the long step maintained on large SUVs?
A: Stability is achieved through the use of two synchronized motors and multiple heavy-gauge mounting points, which distribute the load evenly across the vehicle's frame and eliminate wobble.

Q: Does the system use a lot of power when the vehicle is off?
A: No. The advanced ECU is designed with an ultra-low quiescent current draw (typically <5 mA), ensuring negligible impact on the vehicle's battery health during long periods of inactivity.

Q: Are these steps compatible with the vehicle's factory warranty?
A: Our systems use non-invasive, read-only CAN-Bus integration and bolt-on mounting, meaning no cutting or permanent modification to the vehicle's essential wiring is required, which generally helps preserve the factory warranty.

Core Features

Torsional Rigidity: Dual motors and reinforced linkages eliminate platform flex, providing a secure and confident stepping surface across the entire length.
Subdued Acoustics: Precision machining and sealed bearings minimize mechanical noise, maintaining the quiet cabin environment of luxury SUVs.
Advanced Safety Logic: High-resolution current monitoring ensures immediate stop and reverse if an obstacle is encountered during deployment or retraction.
Corrosion Defense: All steel components receive a multi-stage E-coat and durable powder coat for protection in severe climates.

Production & Customization Services

Production employs Robotic Welding Jigs for perfect dimensional accuracy on all frame brackets. Every ECU is pre-programmed and bench-tested to ensure immediate, error-free communication with the vehicle's specified electronic protocols.

Customization Opportunities:

Custom Step Lengths: Manufacturing steps for extended wheelbase models (e.g., ESV, LWB variants).
Branding/Finishing: Offering private label engraving on the platform surface and custom powder coat color matching to client specifications.
Harness Adaptation: Providing regional-specific wiring harnesses and connector types to meet diverse global market standards.

Material Selection Guide

The platform utilizes 6061-T6 Extruded Aluminum for high strength and optimized weight. The surface is treated with a durable, non-slip texture for maximum grip.

Structural brackets are manufactured from High-Yield Q345B Steel, chosen for its superior yield strength over standard steel, essential for load-bearing components.

Motor housings and electronics are protected by IP67-rated polymer enclosures and feature sealed, temperature-stable lubrication for all internal gears.
