Mobile crane machine

Types of mobile crane machines

• All-terrain cranes

  All-terrain mobile cranes combine the advantages of a cross-country and a flyweight. They are easy to transfer from job site to job site and can travel on public roadways at highway speeds. Once on-site, their rough-terrain capabilities allow them to navigate job sites with relative ease, even if the ground is irregular. Additionally, their high-speed on-road travel makes mobilization for off-site tasks simple.

• Truck-mounted cranes

  Mobile truck cranes are mounted on a truck that provides a driving platform for the crane. They range from small size capacity to large mobile cranes that can be driven on highways. Mobile truck cranes are easy to use and provide flexibility; however, their lifting capacities are less than all-terrain mobile cranes.

• Rough-terrain cranes

  Rough-terrain mobile cranes are ideal for outdoor construction projects where the ground surface may be uneven or rugged, such as roadwork, mining, or landscaping. They can also handle heavy materials, usually oversized. Mobile rough-terrain cranes have large rubber tires and can move around construction sites freely. Their robust wheels allow them to traverse rugged terrain, including mud, gravel, and potholes. Cranes of this type fall into the category of 4WD machines, which receive their power from a solely rough terrain system.

• Crawler cranes

  Mobile crawler cranes are solid and stable due to their wide tracks. They can handle heavy loads with precision and have great manoeuvrability. Crawler cranes also have an embedded permanent magnet that allows them to position themselves with high accuracy. Some Crawler cranes come with LiDAR technology, which helps the equipment have intelligent control. The cranes can work at night or in harsh weather conditions because of their self-sensing and adaptable abilities. Furthermore, relying on the permanent magnet and LiDAR technology, Crawler cranes can sense and avoid dangers autonomously. This quality makes them suitable for offshore wind power, hydropower construction, and power transmission projects.

Specification and maintenance of mobile crane machines

Understanding the mobile crane specifications is crucial when selecting the right machine for a construction project. The key specifications to consider include the load capacity, lifting height, reach, mounting type, rotating ability, control system, and safety features.

• Load capacity: This specification indicates the maximum weight the crane can safely lift. The load capacity of mobile cranes ranges from a few tons for smaller models to several thousand tons for larger off-road and all-terrain cranes.
• Lifting height: The maximum height at which the crane can safely lift objects is indicated by this specification. The lifting height for mobile cranes usually ranges from 50 feet to 200 feet, depending on the model.
• Reach: This specification refers to the maximum horizontal distance the crane can extend from its base. The reach of mobile cranes also varies depending on the model, but it usually ranges from 60 feet to 180 feet.
• Mounting type: This specification indicates how the crane is mounted on a vehicle, which includes the truck-mounted and trailer-mounted types discussed above.
• Rotating ability: This specification refers to whether the crane can rotate its superstructure 360 degrees. Only those cranes with this type of ability are considered to have it.
• Control system: The control system of a mobile crane can be either electronic or remote. A remote-controlled crane is operated using a remote control device that gives commands to the machine from a distance. On the other hand, a crane that is electronically controlled has an electronic system used to regulate its functions and movements.
• Safety features: This specification includes all the safety components of a mobile crane, such as overload sensors, anti-collision systems, limit switches, stability controls, and safety interlocks.

Regular mobile crane maintenance is crucial for optimal performance, reliability, and safety. The machine usually goes through the following process during routine maintenance:

Daily/weekly checks: Operators should visually inspect the crane before and after each use. They should check fluid levels, look for leaks or damaged parts, and test the proper functioning of safety devices and controls.

Monthly inspections: A qualified technician should perform detailed monthly inspections. They should follow the mobile crane manual and focus on critical areas. The mobile crane technician should check components like brakes, steering, suspension, tires, tracks, and hydraulics.

Quarterly servicing: Service mobile cranes on a quarterly basis. During the servicing, follow the schedule in the manual. Check all major systems of the machine, including the engine, transmission, hydraulics, and electrical system.

Annual inspections and servicing: Conduct thorough inspections and servicing of mobile cranes at least once a year. This is an ideal opportunity to closely examine the crane and address any issues. During the annual maintenance, replace critical parts and adjust crucial settings as per the specification and requirements of the mobile crane manufacturer.

Scenarios of mobile crane machines

Mobile cranes play an integral role in diverse industries, accelerating construction tasks and enhancing efficiency.

• Construction projects:

  At construction sites, mobile cranes are indispensable ATM machines. They aid in erecting structures by hoisting beams, columns, and heavy equipment. With their ability to handle substantial weights and versatile reach, mobile cranes facilitate the construction of buildings, bridges, and infrastructures with precision.

• Infrastructure development:

  Mobile cranes contribute significantly to infrastructure development projects. Whether it's erecting towers, signages, or power lines, mobile cranes provide the necessary support. They are also employed in road and bridge construction for tasks like lifting formworks or installing precast segments. Their adaptability ensures the smooth execution of various infrastructure projects.

• Industrial operations:

  Mobile cranes have diverse applications in industrial settings. They are used for plant assembly and maintenance, allowing the installation of heavy machinery and equipment with ease. Mobile cranes also assist in the maintenance of overhead cranes by positioning and connecting components. Their presence streamlines operations and minimizes downtime in industrial facilities.

• Oil and gas operations:

  In the oil and gas sector, mobile cranes are valuable assets. They aid in offshore platform installation, ensuring the proper placement of structures in challenging marine environments. Mobile cranes also facilitate pipeline installation by lifting and positioning heavy pipes. Moreover, they support maintenance and shutdown activities in refineries, helping to maintain operational efficiency.

• Events and entertainment:

  During major events and concerts, mobile cranes become essential to set the stage and construct temporary structures. They provide the necessary support for lighting rigs, sound systems, and video screens. Mobile cranes ensure the safe and timely setup of equipment, enabling smooth event execution and memorable experiences for attendees.

• Demolition and salvage:

  Mobile cranes are instrumental in demolition and salvage operations. Equipped with specialized attachments, they dismantle structures precisely and control their descent safely.
