This is a portable wheel chocking device designed for both professional transportation and civilian safety applications. It addresses the core shortcomings of conventional wheel chocks—including inconvenient operation, restricted field of vision, and insufficient reliability on sloping terrain. The product combines a hand-pull telescopic triangular support structure with an anti-slip rubber base plate, enabling rapid deployment and secure anchoring.

• Telescopic Linkage Mechanism: Equipped with a built-in spring-assisted locking system that automatically engages upon full expansion, eliminating the need for additional fastening operations. For retraction, a one-touch release allows quick and convenient collapse back to storage position.
• Triangular Mechanical Support: Upon expansion, the unit forms a three-point ground-contact plane, delivering high structural rigidity and superior lateral stability compared to traditional wedge-shaped chocks.
• Anti-Slip Base Plate Design: The rubber underside features a textured anti-slip pattern that effectively displaces water films, mud, and fine debris, ensuring adequate friction coefficient even on wet, icy, or loose surfaces.
• Standing-Operation Interface: The handle height and angle are ergonomically optimized to allow operators of approximately 175 cm in height to complete the entire operation process—from deployment to retrieval—without the need to bend or stoop.

• Standing Operation – Safe & Effortless: No bending or squatting required. One hand is all it takes to deploy and position the chock, maintaining a clear field of vision and eliminating safety risks associated with roadside operation.
• Triangular Support – Stable & Anti-Slip: Forms a sturdy triangular structure upon expansion, with a rubber anti-slip base that grips firmly to the ground – reliable even on slopes and wet surfaces.
• Lightweight & Compact – Trunk-Ready: Weighs only 2.5 kg and compacts to a slim size that fits easily in the trunk without taking up valuable space.
• Quality Materials – Durable & Rust-Proof: Constructed from forged and welded aluminum alloy with electrostatic spray coating – strong, lightweight, and corrosion-resistant.
• Flexible Telescoping – Simple Operation: Built-in spring assistance allows for one-pull expansion with automatic locking, and one-touch release for quick retraction and storage.

• It is recommended to use the chocks on both front and rear wheels simultaneously to ensure overall parking safety.
• Before each use, clean the base plate and the ground contact surface to remove oil, grease, gravel, and other foreign matter.
• Periodically inspect the rubber base plate for wear. Replacement is recommended when wear exceeds 1.5 mm.
• Do not use the product on vehicles exceeding the applicable range of 4T. For adaptation to other specifications, please contact us for customization.

Q1: What is this product used for?
A: It is used to secure wheels during parking, preventing vehicles from sliding on slopes, wet surfaces, or during maintenance — essentially a portable "wheel stopper."

Q2: What is the biggest difference between this and traditional wheel chocks?
A: Traditional chocks require bending down or even kneeling to place them, while the RMHs features a hand-pull telescopic design that allows one-hand standing operation — no bending required, offering better visibility and greater safety.

Q3: How does it secure the wheel?
A: When pulled open, it forms a triangular support structure with a 6mm specially formulated anti-slip rubber base. It stays firmly in place through structural weight and rubber-to-ground friction.

Q4: How heavy is it? Is it easy to carry?
A: It weighs only 2.5 kg. When retracted, its dimensions are 151×218×816 mm — slim and compact, easily fitting into the trunk without taking up much space.

Q5: What vehicles is it suitable for?
A: It is suitable for vehicles with a gross weight of 2 to 4 tons, such as SUVs, MPVs, light passenger vans, and light trucks.

Q6: How many units are needed at a time?
A: It is generally recommended to use 2 units per set (for front or rear axle) or 4 units per set (for all four wheels) for maximum safety.

Q7: Are there color options?
A: The standard color is yellow for high visibility. Custom colors are also available upon request.

Q8: Can the size be customized?
A: Yes. The product dimensions can be tailored to specific wheel sizes.

Q9: Can it be used on slopes? Will it slip?
A: Yes. The triangular structure combined with the 6mm rubber base provides reliable grip on slopes and wet/icy surfaces, with excellent anti-slip performance.

Q10: Is it easy to store?
A: Very easy. Press the release button and collapse it in one quick motion — from fully expanded to stored in just seconds.

Q11: Are there any precautions when using it?
A: There are four main points:

• It is recommended to use chocks on both front and rear wheels simultaneously.
• Clean the base plate and ground contact surface before each use to remove oil, gravel, and debris.
• Regularly inspect the rubber base for wear; replace when wear exceeds 1.5 mm.
• Do not use on vehicles exceeding 4 tons. Contact us for customization if needed.

Q12: Sum up its selling point in one sentence.
A: One-hand standing operation, triangular anti-slip stability, lightweight and trunk-ready — parking safety made easy in one move.
