About 23t crane

Types of 23t cranes

A 23-ton crane refers to the lifting capacity of the crane, which is 23 tons, approximately 50,706 lbs. There are different types of cranes used in various industries, particularly the construction sector. The following are some of the most commonly used types of cranes.

  • Gantry cranes: This machine is generally used to lift extremely heavy materials and equipment. It usually comprises a large A-shaped framework with horizontal beams supported by vertical legs. They operate like moving bridges and are mainly used to lift extremely heavy items. Gantry cranes can either be wheeled for moving over a rail track or have wheels for moving on the ground.
  • Jib cranes: Like gantry cranes, this type of crane has a fixed arm that is used to lift equipment or materials. It usually rotates around a vertical mast and is used to provide lateral support for a load. Jib cranes are usually used when sideways movement is required to lift heavy items.
  • Tower cranes: This type of crane is commonly used in large construction projects. The tower cranes are comprised of a tall tower with a horizontal arm attached to it. The tower helps the crane achieve great heights like that of a building. The horizontal arm, on the other hand, determines the range of the crane and can be compared to a bird stretching its wings. The crane operates by either moving loads on a fixed location or on an assembled height similar to that of the crane itself.
  • Roller cranes: Also known as a traveling crane, a roller crane consists of large wheels or rollers mounted underneath the structure. An example of a roller crane is a container crane, which is mainly used in ports for the speedy unloading and loading of containers.
  • Hydraulic cranes: This machine uses hydraulic systems to lift heavy objects. It consists of a movable arm mounted on a chassis or vehicle. They can also be mounted on vessels to help in marine transportation. Hydraulic cranes are usually used in construction projects that require accuracy and control to lift heavy items.

  • Height: The height of the tower crane can generally reach up to 50~60m. It can also be increased as the construction progresses, generally by 3m each time.
  • Jib Length: The maximum horizontal reach of the tower crane is usually 50~60m. It can also be extended or retracted as per the requirement of the construction project.
  • Overall Dimensions: The length, width, and height of the mobile crane when it is stowed are approximately 12m×2.6m×3.8m.

Maintenance Tips

  • Regular Inspection: Regular inspection of the 23t crane should be conducted, such as checking whether the connecting parts are loose, whether the lubrication system works normally, whether the hydraulic system leaks, etc., and timely adjustment, repair, or replacement to prevent hidden troubles.
  • Lifting Operation: The operation of the crane should be in strict accordance with the operating procedures to ensure the safety of the crane and the personnel. During use, overload should not be lifted, and the center of gravity should be balanced to avoid sudden lifting and dropping.
  • Environmental Maintenance: The working environment of the crane should be kept clean. Remove the dust, debris, and other things that affect the normal operation of the crane, and keep the ventilation to avoid overheating and humidity. In a harsh environment, such as high temperatures, low temperatures, etc., the corresponding protective measures should be taken to ensure the normal use of the cranes.

Scenarios of 23t cranes

The following list shows some scenarios where a 23-ton crane works.

  • Heavy transport

    A 23-ton truck-mounted crane lifts and moves heavy materials and equipment like machinery, steel, and concrete at a construction site. The durable tires enable it to drive over rough terrain to places where a normal car cannot go.

  • Installations

    A 23-ton crane helps a technician set up large units such as air conditioners, wind turbines, generators, transmission towers, and radio towers. It can place these objects at high or hard-to-reach spots. The driver may use the boom's outreach and precision control features to do the task with accuracy and safety.

  • Demolitions

    A 23-ton crane can dismantle large structures safely. The demolition expert will attach a concrete cutter or hammer to the crane's hook. The crane will lower the attachment and break the concrete in the desired shape. After this, the crane will lift the debris and load it into a truck.

  • Mining

    A 23-ton crane assists the mining process by moving heavy equipment, materials, and containers. The crane can load ore in large trucks or vessels. It can also offload supply containers from ships. The crane's high capacity reduces the need for extra lifting equipment.

  • Logistics

    In a warehouse, a 23-ton crane lifts and moves heavy pallets first. It may load or offload containers from trucks or at the vessel's berth. The crane boosts the productivity of the logistics firm.

How to Choose 23t Cranes

When choosing a 23-ton crane, several factors need to be taken into consideration:

  • Capacity requirement:

    Users need to determine the weight and dimensions of the heaviest and bulkiest loads to be lifted, as well as the lifting capacity and tonnage required. Also, consider the future capacity requirements to avoid purchasing a crane that is under-capacitated.

  • Type of crane:

    Users should choose the most appropriate crane type to suit their specific lifting needs from the different types of cranes discussed previously. For instance, a tower crane may be best-suited for construction projects, and a mobile crane would be most-ideal if the crane needs to be transported to different locations.

  • Site conditions:

    The conditions of the site where the crane would be used must also be considered. For instance, a mobile crane would be a good choice if the project is taking place over an uneven or inaccessible terrain because of its ability to navigate such landscapes. On the other hand, a tower crane might be better-suited if the project involves reaching great heights and is taking place within an area with limited space.

  • New vs. used cranes:

    Users may consider the option of a new crane versus that of a used crane (that has previously been used before).

  • Cranes with special design features:

    Users may also wish to consider purchasing cranes with special design features, such as an anti-collision system for tower cranes, which prevents multiple cranes from colliding with each other, or load moment indicators that help to measure the load's moment, thereby preventing overloading issues.

23t crane FAQ

Q1: What is the difference between a small and large mobile crane?

A1: Mobile cranes are transported on their own axle and towed behind a trailer by a prime mover. Small mobile cranes, such as a 5 ton crane, can easily be transported to various job sites without the need for special permits. Larger mobile cranes, such as the 23t mobile crane, have the ability to lift much heavier loads and therefore, greater distances.

Q2: How does a mobile crane work?

A2: The three main components of a crane are the base, the hoist, and the arm. The mobile crane's base provides stability and support and is used to level the vehicle when stationary. The hydraulics system in a crane expands and raises the arm to reach and lift heavy materials. The hoist or winch has a wire roped used to lower and lift loads. The mobile crane's loads are usually marked and calculated on the side of the crane hook.

Q3: How are mobile cranes transported from one site to another?

A3: Mobile cranes are mostly transported by road in an over-dimensional load. In some instances, transportation by rail may be possible. Heavy haul trucking or special permits and escort vehicles are required when transporting an oversized load by road.
