Chock block

Types of Chock Block

A chock block is a device used to prevent the movement of a vehicle or a piece of equipment. It is placed behind or in front of the wheels. There are many types of chock blocks, including:

• Wheel chocks

  Wheel chocks are wedge-shaped blocks made of wood or plastic. They are placed behind a vehicle's wheels to prevent backward movement. Wheel chocks are often used in construction sites, mining operations, and shipping docks where vehicles are loaded and unloaded.

• Chocking a block

  Chocking a block refers to the process of securing a block of wood or other material against a larger piece to prevent it from moving. This is often done with large pieces of equipment or vehicles. The chocking process typically involves placing a block of wood or other material against the side of the equipment or vehicle that is most likely to move. The block is then secured in place with ropes, chains, or other fasteners.

• Airplane chocks

  Airplane chocks are large rubber or metal blocks placed against the tires of an aircraft to prevent it from moving when parked. They are especially important for large commercial planes and are used in conjunction with the parking brake. Airplane chocks come in various sizes and weights, depending on the size of the aircraft.

• Boat chocks

  Boat chocks are used to secure a vessel in a slip or dock. They are typically large, heavy blocks made of wood or metal placed against the hull of the boat to prevent it from moving. Boat chocks are especially important in areas with strong currents or waves, where the movement of the water can cause the boat to drift.

Specifications and Maintenance of Chock Blocks

Chock block specifications can vary depending on their application and use. However, here are some general specifications:

• Material

  Chock blocks are made from strong, durable materials that can withstand the force of stopping the moving equipment. Common materials include treated timber, steel, and plastic.

• Size

  Chock blocks come in various sizes. The size is determined by the type of vehicle or equipment that requires the chock block. For large trucks or construction equipment, the chock block size will be large.

• Weight

  The weight of the chock block is very important. Heavier blocks will not move when they are chocked in place. Blocks that are not heavy enough will be unable to stop the equipment from moving.

• Shape

  Chock blocks are usually wedge-shaped. This shape allows the block to fit under the wheels. The wedge shape also prevents the block from moving when placed under the wheel.

• Texture

  Chock blocks have textured surfaces. The texture provides grip and friction. The friction prevents the block from sliding out when placed under the wheels.

Chock block maintenance is important to ensure they can effectively prevent unwanted movement of vehicles or equipment. Here are some chock block maintenance tips:

• Regular Inspection: Users should always inspect chock blocks before and after use. During the inspection, users should check for wear, cracks, or damage. If any chock block is damaged, it should be repaired or replaced.
• Cleanliness: Chock blocks should be kept clean. They should be free from dirt, grease, oil, and other foreign materials. The presence of these foreign materials can reduce friction and increase the risk of slippage.
• Proper Storage: When not in use, chock blocks should be stored in a dry, clean place away from sunlight and extreme weather conditions. The sun's UV rays can damage some materials like rubber or plastic.
• Use the Right Size: Users should ensure that the correct size and type of chock block is used for the specific vehicle or equipment. The size of the chock block should be proportionate to the size of the vehicle tires.
• Regular Replacement: Chock blocks are consumable safety equipment. With time and continued use, they will wear out or become less effective. Therefore, users should have a replacement schedule for the chock blocks.

How to choose chock blocks

When buying a chock block, here are some tips to consider:

• Consider the size

  For any given application, the properly sized chock block should be selected. The size of the chock block should be in proportion to the size of the vehicle or the load being prevented from moving. The chock block should be large enough to prevent movement but not overly large to interfere with the operation of the vehicle.

• Evaluate the material

  Chock blocks are manufactured from diverse materials, like rubber and plastic. Each material has its characteristics and benefits. For instance, rubber chock blocks are very durable and have a high coefficient of friction. This means they do not slide easily, and users do not have to keep replacing them after a short period of time. On the other hand, chock blocks made of plastic are lightweight and resistant to corrosion.

• Consider the surface conditions

  The surface where the chock block will be placed is very important. Some chock blocks are designed for smooth surfaces, while others are more applicable on uneven or rough terrains. Depending on the surface, the buyer should select a chock block with features suitable for that environment.

• Evaluate the visibility

  Visibility is a key aspect when selecting a chock block. It is important to choose a chock block that is easily visible. This helps to prevent accidents where the chock block is not seen, and the vehicle runs over it. Some chock blocks are brightly colored and have reflective markings to enhance visibility.

• Check for additional features

  Some chock blocks come with extra features that may be beneficial depending on the application. Such features include being stackable for easy storage, having handles for easy placement or removal, and being integrated with a rope or chain to prevent loss.

How to diy and replace chock blocks

Chock replacement is not a complicated process. Users have to inspect their chocks regularly and know when to replace them. When replacing, follow the simple step-by-step guide below.

• Safety Precautions:

  Maintain safety measures while changing the chock block. This involves ensuring the trailer or truck is parked on level ground, using proper PPE, and being aware of potential hazards related to the vehicle's surroundings and positioning.

• Assessing the Vehicle's Positioning:

  Check if the vehicle's position is still appropriate before replacing the chock block. If there are concerns about the vehicle's stability or positioning, address those issues before proceeding with the replacement.

• Removing the Old Chock Blocks:

  Take out the chock blocks from the wheel recesses. Depending on the type of chock blocks in use, this may involve removing bolts, straps, or other fastening mechanisms. Inspect the blocks for any damage to help determine the cause.

• Clean the Area:

  After removing the old chock blocks, clean the area where the blocks were installed. This removes any debris, dirt, or residue that may have accumulated and provides a clean surface for installing the new blocks.

• Choosing the Right Replacement Chock Blocks:

  Select chock blocks that are appropriate for the vehicle size, weight, and type. The replacement blocks should be in good condition and free from cracks, splits, or other damage that could compromise their effectiveness.

• Installing the New Chock Blocks:

  Place the new chock blocks against the wheels as per the manufacturer's instructions or the vehicle's requirements. Ensure they fit snugly and are correctly aligned to prevent any movement of the vehicle while parked or stationary.

• Securing the Chock Blocks:

  If the chock blocks are designed to be secured with bolts, straps, or other fastening mechanisms, ensure they are appropriately tightened and secured. This prevents the blocks from becoming loose or dislodged during the vehicle's operation.

• Testing Vehicle Stability:

  Once the new chock blocks are installed and secured, assess the vehicle's stability and positioning. Make sure the vehicle is still in a stable position and that the chock blocks are effectively preventing any movement or shifting.

• Regular Inspections:

  After replacing the chock blocks, do routine checks to confirm that they remain in good condition and that the vehicle's stability is maintained. Address any concerns or issues immediately to ensure the chock blocks' effectiveness and the vehicle's safety.
