When it comes to industrial lifting, double girder gantry cranes are favored for their strength, durability, and high lifting capacities, which range from 20 to over 500 tons. For any business considering investing in one of these cranes, understanding the full cost breakdown—from initial manufacturing to ongoing maintenance—is essential for budgeting and long-term financial planning. Here’s a look at the factors involved in the cost of a double girder gantry crane.
1. Manufacturing Costs
The manufacturing phase is the most significant initial expense in the cost structure of a double girder gantry crane. This includes:
Materials: The primary materials, like high-strength steel and heavy-duty electrical components, make up a large portion of the manufacturing cost. Customization, such as special corrosion-resistant materials or enhanced weatherproofing, can increase costs.
Labor: Skilled labor is required to build, assemble, and test gantry cranes to ensure they meet safety and quality standards. Labor costs vary by region, but they are an unavoidable part of production.
Technology and Innovation: Additional technological features, such as anti-sway mechanisms, remote control options, or automated features, can raise manufacturing costs of gantry cranes. These innovations improve the crane’s operational efficiency but come at a premium.
Design and Engineering: Engineering teams ensure that the crane design meets the specific load, span, and height requirements of the buyer’s application. Custom designs may require additional structural analysis and compliance testing, leading to a slight increase in cost.
2. Transportation and Installation
After manufacturing, transporting a double girder gantry crane to its location and setting it up can be costly.
Transportation: These cranes are large and heavy, often requiring specialized transport. Shipping costs depend on the crane’s size, the shipping distance, and the mode of transport. If the crane must be disassembled and then reassembled at the site, transportation costs can rise.
Site Preparation: In some cases, modifications to the installation site, like concrete foundation reinforcement or track alignment, are necessary, especially for cranes operating outdoors or over uneven ground. Such preparations add to the installation costs.
Installation Labor: Skilled technicians are usually required to install the crane, connect electrical components, and test the system before it becomes operational. Some suppliers include installation support in the purchase price, but others charge separately for these services.
3. Operational and Energy Costs
The crane’s day-to-day operational costs primarily consist of energy consumption and operator wages.
Energy Consumption: Double girder gantry cranes run on electricity, and their energy usage varies with lifting frequency, load weight, and operational speed. Though energy-efficient motors are available, cranes that frequently lift heavy loads can increase power bills.
Operator Costs: Trained operators and supervisors are required to safely operate the crane. Training is often essential to familiarize the team with specific crane functions and safety protocols, and it represents an additional cost.
4. Maintenance and Spare Parts
Regular maintenance is crucial for a double girder gantry crane’s longevity and optimal performance, and this is an ongoing cost.
Preventative Maintenance: Routine inspections, lubrications, and adjustments help prevent wear and tear. Most manufacturers recommend a regular maintenance schedule, including checks on motors, cables, and other components. Some companies offer service packages for this, while others charge on a per-visit basis.
Repairs and Spare Parts: Despite preventive maintenance, parts like hoist ropes, gears, and brakes will require replacement over time. Depending on the brand, spare part availability, and level of customization, replacement part costs can vary.
Upgrades: Technological upgrades, like adding remote control capabilities or modernizing the crane’s software, can improve efficiency and safety but come with additional costs.
5. Decommissioning and Disposal
Though often overlooked, the decommissioning phase is also part of the cost cycle. When a crane reaches the end of its service life, disposal or recycling expenses may arise.
Disassembly and Transportation: This includes labor costs for disassembling the crane, as well as transportation costs to remove it from the site.
Recycling or Disposal: In some regions, there are environmental fees for recycling or disposal of heavy equipment, particularly if the crane contains materials that must be handled responsibly.
Final Thoughts
The cost of a double girder gantry crane is not limited to its upfront purchase price. Factoring in transportation, installation, operational expenses, maintenance, and eventual decommissioning gives a comprehensive view of the investment. Planning for these expenses enables businesses to maximize the crane’s value, ensuring it remains a reliable asset over its service life. By carefully considering each cost factor, companies can make informed decisions that align with their operational needs and budget.
