Heavy Duty Electric Deployable Steps

-- Steady & Reliable Manufacturer --

Technical Overview

The Heavy Duty Electric Deployable Step system is specifically engineered for high-GVWR (Gross Vehicle Weight Rating) SUVs and light commercial vehicles. The core difference lies in the reinforcement of the linkage arms, which are constructed from thicker gauge, Heat-Treated Q345B Steel. The system utilizes a dual-motor configuration on longer steps to ensure balanced, simultaneous deployment and retraction, mitigating torsional strain on the platform.

The electronic control unit is programmed with an enhanced load capacity algorithm. This allows the system to sustain higher static and dynamic loads without compromising the speed or smoothness of the operation. The design incorporates a wider, reinforced mounting plate that connects directly to multiple points on the vehicle's frame structure, maximizing load distribution.

Introduction

When vehicle utility demands go beyond standard passenger use—such as on extended-length SUVs, armored vehicles, or vehicles carrying significant rooftop cargo—a Heavy Duty step is necessary. This product line is built for resilience, providing a secure, stable platform that is rated to handle greater stress and repeated use cycles under challenging conditions.

Bohai Auto Tech applies its manufacturing rigor to this segment by over-engineering the mechanical parts. Our location, near major transportation hubs in Zhejiang, facilitates the efficient logistics required to ship these larger, heavier component systems to commercial and industrial vehicle converters worldwide.

Applications

  • Armored & Security Vehicles: Providing secure and reliable access for vehicles with significantly increased curb weight due to protective layering.

  • Large-Format SUVs: Essential for models such as the Mercedes-Benz GLS US Version or extended-wheelbase SUVs, requiring longer, high-load-capacity steps.

  • Commercial & Industrial Use: Applied to modified SUVs used by surveying teams, oil/gas inspectors, or utility workers who frequently carry heavy equipment.

  • Vehicle Modification Specialists: Suppliers to businesses that specialize in overlanding and extreme off-road vehicle preparation, where component durability is non-negotiable.

Common Questions

  • Q: What is the benefit of a dual-motor system compared to a single motor?
  • A: The dual-motor system distributes the torque load, reduces strain on the individual gearboxes, and, critically, ensures that the long step platform deploys and retracts with uniform speed and stability across its entire length.
  • Q: Does the heavy-duty step still retract flush with the vehicle?
  • A: Yes, despite the increased structural components, the heavy-duty system is designed to fully retract and stow flush against the rocker panel, preserving the vehicle's ground clearance and aesthetics.
  • Q: Are the replacement parts for the motor assembly globally available?
  • A: We maintain a global inventory of common replacement parts, and our motor units are based on a standardized, modular design, facilitating easier servicing and replacement for international partners.

Core Features

  • Enhanced Load Bearing: Engineered with reinforced steel and multiple pivot points to reliably support loads exceeding 450 kg, offering uncompromised stability.

  • Dual-Motor Stability: The use of two synchronized motors on longer steps eliminates deflection and ensures a robust, level platform during use.

  • Industrial-Grade Corrosion Protection: Features a multi-stage pretreatment process followed by a double-thickness powder coat, designed to resist chipping from road debris.

  • Overload Protection: The ECU monitors current draw for both motors, instantly shutting down the system and preventing damage in severe overload or obstruction events.

Manufacturing & Customization

The production of heavy-duty steps involves specialized tooling for working with high-tensile steel. We utilize Plasma Cutting for precise geometry and employ certified welders for structural joining. Every completed frame undergoes a non-destructive Load Test Simulation before being approved for finishing.

Customization Opportunities: We offer specific enhancements for the heavy-duty segment:

  • Extended Lengths: Manufacturing steps for non-standard, extended-cab, or long-wheelbase vehicle conversions.

  • Unique Mounting Brackets: Designing and fabricating custom brackets for chassis that have undergone third-party modifications or armor installation.

  • Custom Traction Surface: Applying specialized abrasive grip tape or high-traction rubber inserts tailored for extreme wet or muddy operating conditions.

Product Display

Material Selection

The fundamental difference lies in the selection of Q345B High-Tensile Structural Steel for the linkage components. This steel grade offers superior strength and yield point compared to standard carbon steel, making it suitable for high-stress, high-load applications.

The step platform may feature Die-Cast Aluminum Components for complex end caps and corners, mated with Heavy Gauge Extruded Aluminum for the main stepping surface, ensuring a non-flexing platform.

Gaskets and seals around the motor and mounting points are made from EPDM Rubber with high durometer hardness, designed to resist permanent deformation under continuous pressure and temperature extremes.
