A mobile crane 50 ton used is a specific model of mobile cranes that can lift a maximum of 50 tons or 100,000 pounds. Mobile cranes are a common type of crane found on many construction sites. They feature an entire crane system built onto a truck or wheeled vehicle. Mobile cranes typically have a set of axles attached to the truck bed or platform, along with a telescoping or swinging arm. This allows them to drive around construction sites and pick things up with their "arm" or boom. Mobile cranes come in many sizes and types, from smaller compact cranes used for interior work to all-terrain cranes for heavy outdoor use.
Due to its high level of adaptability, strength, and mobility, used mobile crane 50 ton is widely used in the fields of infrastructure construction, municipal engineering, electrical power, mining, hydropower, installation, and shipbuilding industries. The specific types of mobile cranes are as follows:
Truck-mounted Crane:
A truck-mounted crane is a mobile crane with a fully integrated vehicle that uses a standard truck chassis to transport cargo. The cargo is lifted or moved using a hydraulic arm or boom. This type of mobile crane has great mobility and flexibility. It can be driven to the desired location like an ordinary truck. After that, the boom or arm can be extended and rotated to start the lifting operation. Due to its simple operation and wide applicability, mobile truck-mounted cranes are commonly used in infrastructure construction, installation, and maintenance.
Soyuz Crane:
This type of mobile crane has a two-axle chassis, a mounted column, and a telescopic boom. Its crane cab and controls are arranged similarly to truck cranes. The boom is telescopic and can be extended. It can be operated completely from the cabin. This gives the operator good visibility of the entire work area. The Soyuz crane can walk and operate freely on rural dirt roads. Because of this, it is suitable for use in open fields and repair of remote transmission lines.
Rough Terrain Cranes:
A rough-terrain crane has large tires to maneuver at worksites and off-road conditions. They often have a four-wheel drive to traverse over rough terrain. The cranes are generally operated by a central control system. A rough-terrain crane excels in moving heavy objects on construction sites and uneven ground. Many feature telescopic booms that extend out and up vertically. They are also used widely in infrastructure, electrical, and mechanical engineering.
In addition to the above-mentioned, all-terrain cranes, acrawler crane, and city cranes are also popular types of mobile cranes.
Specifications to consider when buying a mobile crane 50 ton used include the overall dimension, max lift capacity, max boom length, and engine power. The overall dimension of a mobile crane 50 ton used refers to its length, width, and height when the crane is fully assembled. The overall dimension of a crane will determine if the crane can access a site. For instance, narrow city streets or crowded sites can accommodate cranes with smaller overall dimensions. The max boom length of a mobile crane 50 ton used can affect how far and high loads can be lifted. The longer the boom length, the further its reach and vice versa. The boom length of a crane with an overall dimension that fits the site is usually selected.
Engine power and the lifting capacity are key features of a mobile crane 50 ton used. The lifting capacity determines the heaviest weight the crane can lift. A crane with a higher capacity than required can exert unnecessary stress on the equipment, which may result in a sudden breakdown. Engine power determines the crane’s ability to maneuver objects in different surroundings, construction projects, or industrial settings. Regular inspection and maintenance of a mobile crane 50 ton used can ensure optimal performance, safety, and longevity. The used crane should be regularly lubricated to prevent wear and tear on its parts. The following areas of the crane should be regularly lubricated: boom, pivot points, outriggers and axles.
An inspection routine for a mobile crane 50 ton used should be established. The routine can include a pre-inspection check and post-inspection maintenance of the crane. The operator should conduct a visual pre-inspection check before the crane is used. The operator should look out for signs of damage, wear or leaks in the mobile crane. The operator should also check the fluid levels, including the oil and hydraulic fluid, and ensure all safety features and controls are functioning properly.
After the crane has been used, a post-inspection maintenance procedure should be performed. The procedure can help identify and address potential issues before they escalate. The operator should inspect the mobile crane 50 ton used for any signs of damage or excessive wear. The crane should be serviced regularly to maintain proper function and safety. The servicing schedule can be based on the manufacturer’s recommendations and the frequency of use.
50-ton mobile cranes are useful for heavy construction tasks. Here are some usage scenarios of a mobile crane in a construction project.
Erecting prefabricated structures
A mobile crane can lift heavy and large prefabricated structures like roofs, walls, and entire building sections. It sets them quickly on their foundation with accuracy.
Installation of heavy machinery and equipment
Mobile cranes are often used to install large and heavy industrial machines, generators, assembly lines, HVAC units, and other equipment. Their ability to lift massive weights helps them maneuver these machines that aid production into their operational position with precision.
Steel and Formwork Erection
Mobile cranes are extensively used for the erection of structural components and steel frameworks in construction projects. They are capable of lifting and positioning heavy steel beams, columns, and trusses as well as formwork components with ease.
Wind Turbine Construction
Mobile cranes are commonly used in the construction of wind farms for the erection of wind turbines. They are capable of lifting and positioning the large and heavy turbine components such as the tower sections, nacelle, rotor blades, and other assemblies.
Demolition Projects
Mobile cranes find applications in demolition projects where they are used to dismantle existing structures in a controlled manner. They are suitable for demolishing large and heavy building components, such as columns, beams, roofs, and walls.
Whether looking for a mobile crane for business or personal use, some factors need to be considered before buying. The most crucial part to examine is the lifting capacity and the weight of the crane.
The lifting capacity of the crane must match or exceed the weight of the heaviest material it will lift. This is to prevent dangerous situations that may arise from overloading. If it is unsuitable from an operational standpoint, examine it from a safety standard viewpoint. It is vital for the well-being of both the employees and the integrity of the infrastructure being worked on.
Consider the working radius of the crane. The distance from the crane's center to the point it will lift objects matters. This radius must be considered together with the weight of the object to be lifted. A high working radius capacity means that the crane can lift heavier objects, and when combined with a high working radius, the crane can access far-off places.
The terrain on which the crane will work matters a lot. Mobile cranes can be simple all-terrain vehicles or complex specialist machines used in particular circumstances. For example, rough-terrain cranes with large tires and four-wheel drive are more suited to off-road environments. In contrast, crawler cranes glide on tracks and excel on stable grounds.
Another decision that needs to be made before buying a used mobile crane is how the crane will be operated. Mobile cranes may be operated by radio remotes, pulldown switches, or joystick cranes. The crane's operating system should be examined before purchase to assess the familiarity of the workforce with the crane and minimize the need for training.
The type of crane— crawler, wheeled, forklift, or otherwise— should be determined before purchase. Each type works best in certain industries, such as forklift cranes that may not have the necessary height or sophisticated technology to lift items on construction sites but excel at moving and lifting containers at a port.
Inspect the parts of the crane that matter the most, like the tires, tracks, and suspension system. Also, take a close look at the articulating arm and the hoists and winches of the cranes, as these are the parts that have to bear hefty loads on a constant basis. Apart from these, the engine and hydraulic system should also be inspected, as these provide the necessary power and pressure to lift heavy objects from great distances.
