Fixed Gantry Crane

Overload Protection System

This system is designed to prevent the crane from lifting loads beyond its rated capacity, thus reducing the risk of crane failure or accidents due to excessive weight. When the crane detects an overload condition, the system automatically activates an alarm and disables the hoisting mechanism to prevent further lifting.

Limit Switches

Limit switches are used to prevent the crane’s hoist or trolley from traveling beyond the safe limits of its operating range. They are strategically placed on the gantry crane to ensure that the movement of the load is confined to designated areas, preventing collision with surrounding structures or equipment.

Emergency Stop Button

Every fixed gantry crane is equipped with an emergency stop button, providing a quick and effective way to halt crane operations in the event of an emergency. This button is strategically located in easily accessible areas on the crane’s control panel and at other points on the crane, such as the operator’s cabin and remote control units.

Anti-Sway System

The anti-sway systems work by controlling the motion of the load and minimizing swinging, allowing for more precise and controlled lifting. Anti-sway systems are especially important in applications where precision is crucial, such as in the handling of sensitive materials or equipment.

Wind Speed Monitoring and Control

The wind speed monitoring systems can measure wind speeds and automatically limit crane operations when wind speeds exceed safe thresholds. This prevents accidents such as the crane tipping over or the load swinging uncontrollably due to wind gusts. Wind speed alarms and cut-off features help ensure that lifting operations cease during dangerous weather conditions.

Lifting Capacity and Load Demands

• If the lifting demands are substantial and involve heavy loads on a regular basis, a fixed gantry crane tends to be more suitable. These cranes typically offer higher lifting capacities, are more robust in design, and have a greater load-bearing capability. Stationary gantry cranes are usually more stable, making them perfect for large-scale operations such as steel processing, precast concrete production, and heavy industrial tasks.
• While mobile gantry cranes can handle medium to heavy loads, they may not always have the same lifting capacities as stationary cranes. However, advancements in mobile crane technology are making them increasingly capable of handling heavier loads, but they are typically more suited for tasks that involve flexibility in location rather than massive lifting capacity in one area.

Operational Flexibility and Mobility

• Mobile gantry cranes are the go-to choice when flexibility and mobility are required. For example, in environments like shipyards, docks, or large outdoor storage areas, where the need for crane movement across various locations is high, mobile rubber tyred gantry cranes provide the ability to move between tasks with ease. This is especially beneficial when working on projects that require transporting materials or equipment across wide areas or when multiple smaller tasks are spread across different zones.
• Fixed gantry cranes, by contrast, are optimal when the tasks are highly repetitive and do not require movement. If the crane is meant to stay in one location for continuous operations, such as in a manufacturing line or an assembly area, a stationary gantry crane offers a more efficient and reliable solution.

Infrastructure Considerations

• If your facility already has the necessary infrastructure, such as rail tracks or reinforced floors, a stationary gantry crane is an excellent choice. These cranes can be installed directly onto the existing infrastructure, providing a stable and long-lasting solution for heavy duty lifting.
• However, if you’re operating in a rented warehouse or facility, where making permanent modifications to the ground is not an option or where there is concern about surface integrity, a mobile gantry crane will be far more appropriate. Since mobile cranes don’t require track installation or any permanent modifications to the space, they provide the flexibility to move within the facility without damaging the existing ground surface.

Long-Term Business and Project Needs

• Consider the long-term nature of your projects. If your project involves consistent and heavy lifting in a stable, fixed location, a stationary gantry crane will provide greater durability, lifting capacity, and efficiency for ongoing tasks. It is the best choice for long-term, high-volume operations where crane relocation is not necessary.
• However, if your business operates across multiple projects or your worksite layout changes frequently, a mobile gantry crane is the better investment. These cranes allow you to relocate the crane as needed, saving on installation and modification costs.

Inspect Structural Components

Check the frame, beams, and supports for wear, cracks, or corrosion. Pay attention to joints and welds.

Frequency: Monthly or more often in harsh environments.

Lubricate Moving Parts

Regular lubrication of bearings, gears, and trolley wheels is necessary to prevent friction and wear.

Frequency: Every 500 operating hours or every 3 months.

Hoist and Trolley Maintenance

Inspect the hoist and trolley for cable wear, motor function, and smooth movement.

Frequency: Every 3–6 months.

Wheel and Rail Check

Examine wheels for wear and ensure the rails are clear and aligned to avoid operational issues.

Frequency: Monthly or more often for high-load cranes.

Electrical System Check

Inspect wiring, controls, and emergency stop systems for wear or damage.

Frequency: Every 3 months.

Brake System Maintenance

Ensure brake pads, hydraulic, and air systems are in good condition to maintain safety.

Frequency: Every 6 months.

Load Testing

Test the crane’s load capacity regularly to confirm it’s operating at full capacity.

Frequency: Annually or after major repairs.
