Understanding Jacking and Skidding in Heavy Load Handling

Jacking and skidding are essential techniques in the field of heavy load transportation and positioning, particularly in the UAE where industrial growth demands the movement of large, complex, and often fragile equipment. These techniques are used when traditional lifting or rolling methods are impractical or unsafe. The process requires precise engineering, specialized equipment, and experienced operators.

What Is Jacking?

Jacking refers to the controlled lifting of a heavy load using hydraulic jacks. This method is typically employed when there's a need to elevate heavy equipment such as transformers, turbines, generators, or structural components for relocation, installation, or maintenance.

Types of Jacking Techniques

• Hydraulic Jacking: Utilizes high-pressure hydraulic cylinders to lift massive weights with stability and control.
• Mechanical Jacking: Employs mechanical screw jacks where hydraulic systems aren't feasible.
• Synchronous Jacking: Ideal for precision tasks, this technique uses computer-controlled hydraulic jacks to lift evenly, ensuring structural integrity.

What Is Skidding?

Skidding is the lateral movement of heavy loads along a guided path using skid tracks and push-pull hydraulic systems. Skidding is often paired with jacking when the load needs to be relocated horizontally after being lifted.

Components Involved in Skidding Systems

• Skid Tracks: Made from high-strength steel or aluminum, providing a stable pathway.
• Skid Shoes: Placed beneath the load to distribute weight and reduce friction.
• Push-Pull Units: Hydraulic systems that enable forward and backward motion.
• Load Monitoring Devices: Ensure safety by continuously measuring weight distribution and load shift.

Why Jacking Skidding Are Vital in the UAE

The UAE's rapid infrastructure development and energy projects require frequent relocation of massive components. Whether it's oil and gas, power generation, or civil engineering, jacking and skidding systems provide a cost-effective, efficient, and safe alternative to cranes and large-scale lifting equipment, especially in confined or structurally sensitive environments.

Industries That Rely on Jacking and Skidding in the UAE

• Oil Gas Sector: Moving pressure vessels, heat exchangers, and modules.
• Power Utilities: Installing turbines, generators, and transformers.
• Aerospace: Relocating large parts and testing equipment.
• Civil Infrastructure Projects: Bridge launching and structural repositioning.
• Manufacturing: Machinery relocation and plant assembly.

Advanced Equipment Used in Jacking and Skidding

In the UAE, top-tier service providers utilize state-of-the-art equipment to ensure precision and safety during heavy load movement.

Hydraulic Jacks

These jacks are available in capacities ranging from 50 to 1000+ tons, offering vertical lifts with extreme accuracy. Multi-point lifting systems are synchronized through a central control panel.

Skidding Systems

Modern systems feature Teflon-coated skid tracks, low-friction surfaces, and high-capacity push-pull cylinders that enable smooth lateral motion, even on irregular surfaces.

Remote Monitoring and Control Systems

Some setups integrate real-time load sensors, automated feedback systems, and remote-control technology to provide live monitoring, enabling technicians to make immediate adjustments.

Step-by-Step Overview of Jacking and Skidding Process

1. Site Inspection and Planning

Every successful project begins with a detailed assessment of the site and load. Engineers evaluate the ground conditions, load center of gravity, weight distribution, and space constraints.

2. Load Preparation

The load is stabilized, reinforced, and positioned correctly before lifting. Load-specific lifting lugs or platforms are used to avoid structural damage.

3. Jacking Phase

Hydraulic jacks are placed strategically beneath the load. In synchronous systems, all jacks lift the structure at the same rate, minimizing stress and ensuring balance.

4. Installation of Skid System

Once elevated, skid tracks and skid shoes are inserted. The load rests securely on these shoes, which are designed to glide with reduced resistance.

5. Skidding and Positioning

Using hydraulic push-pull units, the load is slowly moved along the skid track toward its new location. The process is controlled to avoid sudden shifts.

6. Final Positioning and Lowering

Once the destination is reached, the load is carefully lowered into position using the jacking system. Precision alignment ensures operational readiness.

Benefits of Jacking and Skidding in Heavy Load Projects

• Minimal Disruption: Ideal for operational facilities where crane access is limited.
• Cost Efficiency: Reduces need for large-scale crane rentals and additional manpower.
• Enhanced Safety: Controlled systems reduce the risk of accidents.
• Flexibility: Works effectively in confined spaces or complex terrains.
• Precision: Allows micrometer-level accuracy in positioning.
