High-Torque IP68 Motorized Running Boards

-- Steady & Reliable Manufacturer --

Technical Overview

These motorized running boards are defined by a high-torque, purpose-built DC motor unit encased in an IP68-rated, hermetically sealed enclosure. This system is specifically designed to function reliably after exposure to water submersion (up to 1m), dust, mud, and ice. The motor is paired with a heavy-duty, low-backlash worm gear drive that delivers sustained force, capable of breaking through frozen debris or overcoming resistance from heavy fouling.

The internal gear set utilizes synthetic, low-viscosity lubricant that maintains performance stability across an extreme temperature range (e.g., −40∘C to +80∘C), ensuring consistent deployment speed in any climate.

Introduction

For environments that punish vehicle accessories—from deep mud trails to regions using heavy road salt—these IP68 high-torque steps are the necessary solution. They eliminate the concern of mechanical failure due to environmental ingress, offering relentless performance where standard steps might fail. They are built for resilience, not just convenience.

BHTC dedicates specific engineering resources to sealing and torque specification for this product line. We provide the assurance of reliable, all-weather function, critical for customers in utility, fleet, and extreme-climate markets.

Applications

Extreme Off-Road Vehicles: Essential for vehicles that frequently encounter water crossings, deep mud, or sand (e.g., Tank 300, modified trucks).
Arctic/Winter Climates: Ensures reliable deployment and retraction in sub-zero temperatures and when the steps are covered in thick ice or snow.
Mining and Industrial Fleets: Provides reliable access in environments with high levels of corrosive dust, solvents, and operational debris.
Coastal/Maritime Use: The IP68 sealing provides superior defense against salt air and pervasive humidity, protecting the internal electronics.

Common Questions

Q: What specific tests confirm the IP68 rating?
A: We conduct both a 6-hour dust exposure test (full ingress protection) and a 30-minute submersion test under 1.5 meters of water to certify the motor and ECU enclosures as IP68 compliant.

Q: Does the high-torque motor consume significantly more battery power?
A: The ECU manages current draw. High power is only utilized momentarily when overcoming resistance (e.g., breaking ice). During standard operation, power draw is similar to standard steps, and quiescent draw is ultra-low.

Q: How do you prevent internal corrosion within the sealed motor unit?
A: The internal components are protected by specialized coatings and non-corrosive, synthetic grease. The hermetic seal prevents the introduction of atmospheric moisture and corrosive elements.

Core Features

Relentless Deployment: The high-torque motor and robust gearing ensure reliable function, even when the linkage is fouled by frozen contaminants.
Submersible Reliability: The IP68 rating guarantees that dust, water spray, and temporary water immersion will not compromise the motor or electronics.
Thermal Stability: Specialized synthetic lubricants prevent viscous drag in extreme cold and maintain protective film strength in extreme heat.
Vibration Resistance: The robust gear casing and mounting are designed to endure continuous, high-intensity vibration from rough terrain.

Production & Customization Services

Production includes a mandatory Pressure Test for every motor casing to confirm the IP68 seal integrity. The assemblies undergo Thermal Shock Cycling in a climate chamber to verify performance at temperature extremes.

Customization Opportunities:

Integrated Heating: Offering optional low-voltage heating elements within the step platform for rapid de-icing in specific extreme cold markets.
High-Security Wiring: Providing armored external wiring conduit for use in high-risk environments (e.g., undercarriage protection against rodent damage or abrasion).
Custom Torque Mapping: Programming the ECU firmware to provide a specific, even higher initial torque surge for clients operating in regions known for persistent freezing conditions.

Material Selection Guide

The motor housing is made from a Reinforced, Glass-Filled Nylon Polymer, providing superior resistance to impact and chemical exposure compared to standard plastics.

Internal motor shafts and critical fasteners utilize Stainless Steel or Chemically Nickel Plated Steel for maximum internal corrosion defense.

The wiring harness utilizes Silicone or TPE Jacketing and Sealed Deutsch-Style Connectors to ensure the electrical integrity of the system in wet conditions.
