Forklift crane arm

Types of forklift crane arms

Forklifts are heavy-duty vehicles, and forklift crane arms are attachments designed to help extend their duties and versatility. Crane arms allow forklifts to carry loads they would not otherwise be able to bear or reach.

• Extender: The most basic design of a forklift crane arm is that of a simple extender. This is a straight piece of metal attached at one end to the forklift and at the other to a load or item of weight. An extender works best when weight distribution is even and simple loads are carried. However, it does not suffice when heavy or awkward loads are to be carried, as the lack of a support system leads to instability.
• Crane Attachment: This system involves a hoist or a crane built into the arm. Hoists have their own systems of support, which makes them ideal for use with forklifts when carrying heavier loads. Cranes have the added advantage of being able to rotate, allowing for more versatility and ease of placement.
• Suspension Support: This is an attacher that has a suspension system of a hammock-like item that has the load placed on it. It acts as a catcher for awkwardly shaped items that need to be carried. An example of suspension support is a pallet or skid that is attached to the suspension system. This is a versatile method for carrying some items that do not fit standard molds.
• Forklift Jib Crane: This particular crane arm has multiple designs. It is a popular crane arm design for forklifts, where a T-shaped crane support is used. It usually requires more than just one support to bear the weight of the load being carried by the forklift. The jib crane works best for lifting materials or loads from a distance and is excellent at moving items horizontally. Many suppliers offer various forks for customization to suit individual clients' needs.

Specification and Maintenance of Forklift Crane Arms

Specification

• Material

  Heavy-duty forklift crane arms are commonly constructed using high-strength steel or aluminum alloy. Steel possesses exceptional strength and weight-bearing capabilities, as well as resistance to deformation, making it suitable for extensive use. Its strength and tensile properties make it a widely adopted material in the industry. Aluminum alloy, on the other hand, is lighter and more rust-resistant, allowing for easier handling of heavy objects with forklifts. It's important to note that although aluminum alloy cranes may have slightly lower weight-bearing capacity compared to steel, they can still effectively handle the majority of loads in a warehouse setting.

• Load Capacity

  Load capacity refers to the maximum weight a crane arm can safely lift and is typically measured in tons. Common load capacities for forklift crane arms include 1 ton, 2 tons, 3 tons, 5 tons, 10 tons, 20 tons, and up to 50 tons. Selecting the appropriate load capacity for a forklift crane arm is crucial to ensure that the arm can handle the intended weight without compromising safety.

• Lifting Height

  The lifting height of a forklift crane arm refers to the maximum height to which the arm can lift objects. Depending on the model, this can range from several feet to over 20 feet. For example, a forklift equipped with a 6-foot crane arm can lift items up to 6 feet high, while one with a 12-foot crane arm can reach up to 12 feet. The lifting height is determined by the length of the crane arm itself. Selecting the appropriate lifting height is important to ensure that the arm can reach the desired elevation for tasks such as stacking or accessing elevated areas.

Maintenance

• Regular Inspection

  It is crucial to routinely inspect the forklift crane attachments for any signs of damage, such as cracks, bends, or deformities. Pay special attention to critical components like forklift crane brackets, which connect the crane to the forklift; the pivot points that allow the crane to maneuver; and the lifting chains or ropes that bear the weight. By examining these key areas, one can identify potential issues early on and take appropriate measures to address them, ensuring the continued safety and functionality of the crane.

• Lubrication

  Proper lubrication of moving parts is crucial for maintaining the optimal performance of heavy-duty forklift cranes. Regularly apply lubricant to pivot points and rotating components to ensure smooth operation. Lubrication minimizes friction, reduces wear and tear, and extends the lifespan of the crane. Additionally, regularly greasing forklift crane attachments helps prevent rust and corrosion, further preserving their functionality. By maintaining proper lubrication, businesses can enhance the longevity and reliability of their heavy-duty forklifts and crane attachments.

• Cleaning

  Keeping forklift crane arms clean is important to preserve their proper functioning and prolong their lifespan. Regular washing removes dirt, grease, and debris that accumulate over time and can damage delicate parts. When cleaning the crane, it is advisable to use mild detergent and water instead of harsh chemicals that could harm the equipment. Ensuring the crane is completely dry before use helps prevent the risk of slipping or rust formation. Establishing a regular cleaning routine is essential for maintaining the integrity and performance of forklift crane arms.

Scenarios

The extension arms for forklifts are widely used in industries with heavy loads or high stacking requirements. Here are some key applications of forklift attachments with crane arms in various industries.

• Construction Sites

  Construction sites often use a forklift crane arm to transport large structures such as steel beams, trusses, and prefabricated modules. The ability to extend and maneuver loads at heights makes them indispensable for creating a stable framework.

• Warehousing

  In a warehouse with heavy pallets stacked high, a forklift with an extension arm can create vertical storage. The crane arm easily adds pallets in a limited floor space while minimizing the risk of property damage and worker safety.

• Infrastructure Projects

  Infrastructure projects such as bridges, highways, and tunnels often involve the use of large, heavy components that need to be positioned with precision. If they have a crane attachment, they can easily install these components with accuracy and safety from one point to another.

• Renewable Energy

  Renewable energy projects, such as solar farms and wind farms, often require the transportation and installation of large, heavy components. Forklift cranes can easily position these components, such as solar panels, wind turbine generators, and towers with precision and safety.

• Shipyards

  Heavy load arms for forklifts are commonly used in shipyards to assemble and maintain large vessels. The arm can easily position heavy and awkward ship parts, such as hull sections, engines, and scaffolding, and facilitate loading and unloading.

How to choose forklift crane arms

Here are some critical factors to help buyers select the right forklift crane attachment for their specific needs:

• Goods Weight and Size

  Workload weight and dimensions are essential considerations when selecting a forklift lift arm attachment. The primary function of a forklift crane arm is to lift heavy loads. Therefore, it is important to consider the weight and dimensions of the goods to be lifted.

• Capacity of the Forklift

  When choosing a forklift crane attachment, it's essential to consider the forklift's capacity. Crane arms are designed to increase the reach and lifting capability of forklifts. However, they may also distribute the weight differently and increase the center of gravity.

  It is, therefore, vital to ensure that the forklift's capacity is sufficient to handle the weight of the load coupled with the crane attachment's weight.

• Compatibility with the forklift
