With advanced technology, based on FEM (Europe), DIN (Germany), ISO(International) crane standards, with the features of Strong rigidity, light dead weight, low power, outstanding structure design etc. The European standard industrial gantry cranes can be used in the underground rail construction site, and construction site of well or tunnel or shaft in the subway building.

• Designed based on FEM, DIN, and ISO crane standards
• Strong rigidity with light dead weight
• Low power consumption and outstanding structural design
• Ideal for underground rail, tunnel, well, or shaft construction

The industrial cranes are also need in the bridge construction and erection for heavy duty loads handling , especially for the transporting and delivery of prefabricated beams, with the features of good stability, high efficiency, safety and reliability, variable span convenient adjustment and convenient operation and etc.

• Handles heavy-duty loads in bridge construction and erection
• Good stability, high efficiency, and safety
• Variable span and convenient adjustment
• Ideal for transporting and delivering prefabricated beams

Lifting equipment can be expensive to purchase or rent. Contractors must account for purchase or rental costs, maintenance, repairs, and replacement parts when planning budgets.

Cost management strategies include careful budgeting, sharing equipment with other contractors, or renting as needed to reduce expenses.

Lifting equipment may not always be available for large or complex projects. Contractors must plan ahead to ensure timely availability, coordinating with rental companies or other contractors.

Alternative equipment or methods may also be considered if the required lifting equipment is unavailable.

Equipment productivity affects project timelines and success. Contractors must ensure equipment handles required loads efficiently to avoid delays.

Maximizing productivity involves proper maintenance, efficient use, scheduling repairs, optimizing load placement, and choosing the appropriate equipment type.

Contractors must comply with regulations and standards such as OSHA, ANSI, and other safety and load guidelines.

Compliance can be ensured by staying updated on regulations, conducting inspections and audits, and providing staff training on compliance requirements.

RTGs are mobile cranes on rubber tires, allowing easy movement without permanent foundations. They lift heavy loads to moderate heights and transport materials or equipment around the job site.

RMGs are mounted on rails, can lift heavy loads to great heights, and move easily along the rail system. They are ideal for precast concrete segments, steel beams, and other heavy materials.

Both RTGs and RMGs offer mobility and lifting capacity advantages for metro construction projects. Choosing the right type depends on site space, terrain, and material weight/size. Engineers or crane manufacturers can assist in selection.

Semi-gantry cranes are useful where space is limited or terrain is uneven. Supported by one leg and a runway system, they can move along the runway to lift and move loads.

They are ideal for lifting precast concrete segments, steel beams, or heavy materials and transporting equipment or materials around the site.

Semi-gantry cranes are practical when a full gantry crane system is not feasible.

Container cranes lift and move shipping containers transporting construction materials and equipment. They are efficient for moving large amounts of materials quickly on site.

Typically mounted on rails or support systems, they move easily to reach different site areas. While not for lifting precast concrete segments, they are valuable for moving materials and equipment efficiently.

Yes, gantry cranes can be used in underground metro construction projects, but they need to be designed to fit the specific requirements and limitations of the underground space.

Things to consider for underground material handling

When the lifting height of a crane covers the depth of an underground area, there are several things that should be noticed to ensure safety:

• Check for underground utilities: Before beginning any excavation work, check for gas lines, water pipes, and electrical cables to prevent accidents and damage.
• Ensure proper ventilation: Use ventilation fans or natural ventilation to prevent buildup of toxic gases.
• Use proper lighting: Bright, high-quality lighting is essential to illuminate the work area.
• Ensure stability of the crane: Use outriggers or stabilizers to prevent the crane from tipping over.
• Use proper lifting equipment: Use slings, chains, and shackles to secure heavy loads.
• Follow safety guidelines: Wear appropriate PPE such as hard hats, safety glasses, and gloves, and follow safe work practices at all times.

When material handling involves both above and underground operations, it is important to confirm the lifting height to ensure safety and avoid accidents. Here are some steps to confirm the lifting height:

• Measure the distance: Measure the distance between the above and underground areas using a measuring tape or other tools.
• Determine the maximum lifting height: Consider the height of the upper area, the depth of the underground area, and other factors affecting lifting height.
• Check for obstructions: Look for overhead power lines, tree branches, or other obstacles.
• Use proper lifting equipment: Ensure cranes, hoists, and slings are appropriate and secure.
• Follow safety guidelines: Wear PPE, follow safe practices, and maintain equipment properly.

• Safety procedures: Establish procedures for inspecting equipment, securing loads, and positioning workers.
• Communication: Ensure workers can communicate with equipment operators for safe and efficient operations.
• Equipment maintenance: Regular inspections and repairs prevent accidents and extend equipment life.
• Load capacity: Only lift loads within equipment capacity and train workers accordingly.
• Environmental factors: Consider weather, temperature, and humidity affecting operations.
• Emergency procedures: Train workers for shutdowns, evacuations, and accident responses.

There are several types of lifting equipment commonly used in above and underground areas:

• Cranes: Use hoists and wire ropes or chains to lift heavy loads. Types include tower cranes, mobile cranes, and overhead cranes.
• Hoists: Lift loads vertically using chains or wire ropes, ideal for underground areas. Available in electric, hydraulic, and manual models.
• Slings: Support and lift loads using wire rope, chain, or synthetic materials in various configurations.
• Aerial lifts: Lift workers to elevated work areas. Types include scissor lifts, boom lifts, and personnel lifts.

Using the appropriate lifting equipment ensures material handling and lifting operations are conducted safely and efficiently.
