Specification and Maintenance of Big Chocks

There are several types of big chocks, and each type is designed to meet specific applications and needs. Here are some general specifications of big chocks:

• Material

  Generally, big chocks are made from different types of materials. Each material offers different advantages and features. Some of the common materials used in making big chocks are plastic, aluminum, and steel. Chocks made from steel are known for their strength and durability. This makes them ideal for heavy-duty applications. On the other hand, plastic chocks are lightweight and resistant to corrosion.

• Size and Weight

  Big chocks are available in different sizes and weights. Usually, the size and weight of the chock will determine its level of application. That is, a heavier and larger chock will offer more stability and support compared to smaller and lighter chocks. Chocks come in different sizes ranging from lengths of 8 inches (20 centimeters) to 12 inches (30 centimeters) or more.

• Surface Texture

  Big chocks come with different surface textures. The surface of the chocks can be embossed, textured, or patterned. The surface texture is usually important because it offers more grip and traction. This further prevents slippage and accidental movement.

• Load Capacity

  Big chocks are designed to support different load capacities. The load capacity of the chocks is determined by the material and size. For instance, chocks made from steel can support heavier loads compared to those made from plastic. Big chocks are designed to support load capacities ranging from 2,000 pounds (900 kilograms) to 20,000 pounds (9000 kilograms) or more.

Proper maintenance of big wheel chocks is very important. This is because it helps to enhance their performance and also increase their lifespan. Here are some general maintenance tips for big chocks:

• Inspection: Carry out regular inspections to check for any signs of damage, wear, or cracks.
• Cleaning: Big chocks should be cleaned regularly to prevent the accumulation of dirt, oil, or debris.
• Moisture: Chocks made from wood should be kept away from moisture or water to prevent rotting.
• Proper Storage: Chocks should be stored in a dry place away from direct sunlight.

How to Choose Big Chocks

• Chock Size vs. Wheel Size

  When selecting a proper size chock, consider the size of the wheels on the vehicles to be chocked. A well-sized chock will fill the space alongside the wheel to prevent movement.

• Big Chock Shape and Design

  Wedge chocks work well for most flat-surfaced areas, as their wedges can grip underneath wheels on concrete, asphalt, or packed ground. However, if the vehicle will be parked on a slope, a more angled or triangular chock can better stop rolling.

• Material Considerations

  Rubber big chocks provide a good grip in most places due to their textured bottoms. However, if a chock needs to be very heavy to withstand strong forces, metal or composite material chocks can offer more weight and strength.

• Environmental Conditions

  For outdoor use, choose chocks made from weather-resistant materials like treated wood or coated metals. These will better withstand rain, snow, and UV exposure. In very cold areas, rubber should be used cautiously as it can become brittle.

• Size and Weight of Vehicle

  For smaller cars and light trucks, 6x9-inch or similarly-sized chocks are usually sufficient. However, for large 18-wheel trucks and freight, much larger chocks measuring 12x24 inches or more should be used to stop movement.

• Chocking Technique

  Always place two chocks at the rear wheels and two at the front wheels, equally spaced, to fully secure a vehicle both forward and backward. This prevents rolling in either direction. The chocks should fit snugly alongside the wheels without excessive gaps.

• Regulatory Compliance

  Check local laws about minimum required sizes and materials of chocks for commercial use. Some places have standards for construction, trucking, and other industries to prevent accidents safely.

• Storage and Transport

  For mobile use, select chocks that are not too heavy for workers to carry. Chocks with handles or tie-down points can be easily transported to job sites. For infrequent use, consider stackable chocks that take up less storage space.
