1T Portable Gantry Crane Exported to UAE: Designed for Soft Soil and Coastal Conditions

We customized a 1-ton foldable portable gantry crane for a customer in the United Arab Emirates, mainly used for material handling in a private garden. Considering the challenging site conditions—soft soil prone to sinking and severe corrosion from coastal salt spray—we implemented three key engineering upgrades: large-size widened rubber wheels, full powder-coated steel structure and hoist body, and galvanized lifting chain. The equipment has passed full pre-shipment assembly testing and is ready for packing and dispatch.

Procurement Requirements: Soft Ground Operation & Coastal Corrosion Protection

The customer in the UAE required a simple but practical solution: a 1t kren gantri mudah alih with a 2m span and 3m lifting height, intended for daily material handling in a private garden.

From a technical perspective, this is a standard low-capacity portable gantry crane that we have produced many times. However, one key detail changed the entire engineering approach: The equipment will be used on soft soil in a garden, where standard wheels are prone to sinking, making normal movement and operation difficult.

Based on this condition, we recommended upgrading from standard wheels to large-size widened rubber wheels to improve ground adaptability. After evaluating the site conditions, the customer approved the solution.

Later during production, the customer further informed us that the equipment would ultimately be used near a beach area. Long-term exposure to sea wind, humid air, and salt-laden environments would significantly accelerate corrosion. Therefore, the standard anti-corrosion configuration was no longer sufficient, and the overall corrosion protection system needed to be upgraded accordingly.

Customized Design of Portable Gantry Crane: Wide Rubber Wheels, Anti-Corrosion Coating & Galvanized Chain

To ensure stable long-term operation under soft soil and coastal conditions, we optimized the equipment without changing the core structure or significantly increasing cost, focusing on targeted improvements in mobility and corrosion resistance.

Widened Rubber Wheels for Soft Ground

The original standard wheels have limited ground contact area, resulting in higher ground pressure. On soft soil, this can easily cause sinking during movement, affecting operational efficiency.

To solve this issue, we upgraded the crane to large-size widened rubber wheels. By increasing the contact area and reducing ground pressure, the crane can move smoothly on soft surfaces without sinking.

After the upgrade, the equipment can be operated on grassland and soft soil without additional ground reinforcement such as steel plates or concrete flooring, ensuring stable mobility under both unloaded and rated load conditions.

Three Anti-Corrosion Measures for Coastal Environments

The main challenge in coastal applications is salt spray corrosion. Moist, salt-rich air rapidly accelerates metal degradation. To address this, we upgraded three key components: steel structure, hoist body, and lifting chain.

1. Full Powder Coating for Steel Structure: All structural components—including main beams, legs, and base beams—are treated with a full powder coating process. Compared with traditional paint, powder coating provides stronger adhesion, better surface uniformity, and significantly improved weather resistance, making it highly suitable for high-humidity, high-salinity environments.
2. Full Powder Coating for Electric Hoist Body: Unlike conventional small gantry cranes where hoists typically receive only basic paint protection, this project applies full powder coating to the entire hoist body. This ensures consistent corrosion protection across the entire machine, eliminating weak points in the system.
3. Galvanized Lifting Chain: The standard carbon steel chain was upgraded to a hot-dip galvanized lifting chain. As one of the most frequently exposed load-bearing components, the chain benefits from a dense protective zinc layer that effectively resists moisture and salt corrosion, ensuring safe and stable lifting performance.

Why Not Choose a Full Stainless Steel Solution?

During the technical discussions, the customer also inquired about a full stainless steel version.

Stainless steel does offer better corrosion resistance, but for this type of portable gantry crane that requires frequent movement and foldable storage, it would significantly increase both the weight and the cost.

An approximate 50% weight increase would reduce portability and make manual handling more difficult, while also significantly increasing manufacturing cost.

After evaluating corrosion resistance, weight, and budget, the customer ultimately selected the powder-coated structure with galvanized chain solution, achieving a balanced performance between durability and portability.

Portable Gantry Crane Successfully Completed Factory Testing

• From initial inquiry to final confirmation, both sides conducted multiple rounds of technical discussions focusing on wheel configuration for soft ground, corrosion protection strategies, and the feasibility of stainless steel alternatives.
• After manufacturing was completed, we carried out full pre-shipment assembly testing, including folding mechanism operation, mobility testing, and inspection of all customized components.
• The results confirmed smooth operation, stable movement, and full compliance with design requirements for all upgraded configurations.
• The 1T Foldable Portable Gantry Crane customized for soft soil and coastal conditions in the UAE has now passed factory testing and is ready for shipment.

Get Your Customized Solution

With years of experience in crane manufacturing, DAFANG CRANE understands that small-capacity lifting equipment often faces complex real-world challenges that standard models cannot fully address. Soft ground conditions, coastal corrosion, limited spaces, and special storage requirements often require tailored engineering solutions rather than standard configurations.

No matter your project location, working environment, or lifting requirements, we provide fully customized portable gantry crane solutions designed around your real operating conditions.

We do not rely on template designs. Instead, we evaluate your site conditions, environment, and usage requirements to deliver a solution that is stable, durable, and cost-effective.
