Three of the most popular options for lifting on construction sites are gantries, chain blocks or chain hoists, and block grabs. In this guide, we will explain what they are, what they lift, when you should use each one and five benefits of using these types of equipment on a construction site.
Top Benefits of Using Lifting and Handling Aids
- Reduced Risk of Injury: These tools reduce the physical strain on workers, thereby decreasing the likelihood of musculoskeletal injuries.
- Increased Efficiency: They make manual tasks easier and faster, reducing the time taken to complete tasks.
- Improved Safety: They minimise the risk of dropped or unbalanced loads and structural damage.
- Better Control: Lifting aids provide workers with greater control over loads, reducing the risk of accidents.
- Increased Productivity: By making tasks quicker and easier, these aids can increase productivity and reduce the time taken to complete tasks, leading to faster project completion times.
Gantries
Gantries consist of a horizontal beam supported by two vertical legs. They are commonly used in construction, warehousing, and manufacturing to lift heavy items such as steel beams, machinery, and containers and come in a range of sizes and weight capacities.
When to use gantries:
- When lifting items to a height that is not easily reached by other lifting equipment
- When lifting heavy items that require a stable, overhead support system
- When working in an area with limited access or space
Expert advice:
- Conduct regular inspections of the gantry for signs of wear and tear or broken parts, and make sure all safety devices are working.
- Plan your lifts, ensure the lift path is clear and the load correctly balanced.
- Never exceed the gantry's maximum load capacity.
Chain Blocks or Chain Hoists
Chain blocks and chain hoists are both types of mechanical lifting devices that use a chain to lift and move heavy objects. They are often used to lift items such as engines and heavy machinery.
When to use chain blocks or chain hoists:
- When lifting heavy items that require precision control
- When working in a confined space where other lifting equipment cannot be used
- When lifting items to a height that is not easily reached by other lifting equipment
Expert advice:
- Regularly maintain and lubricate your chain hoists or blocks.
- Always stay within the lifting capacity of the equipment to prevent overloading.
- Control the speed when lifting or lowering loads to prevent accidents.
Block Grabs
Block grabs are used to lift and move large, heavy blocks of stone, concrete, or other materials when building walls and retaining structures. They consist of two arms that grip the block from either side, and a central pivot point that allows the block to be rotated.
When to use Block Grabs:
- When lifting and moving large, heavy blocks of stone, concrete, or other materials
- When working on a construction site where heavy blocks need to be moved or placed
- When precision placement of the block is required
Expert advice:
- Always inspect the block grabs before use for signs of damage or wear.
- Ensure that the blocks fit within the grab arms and are not oversized.
- Always balance and center the block before lifting.
Gantries, chain blocks or chain hoists, and block grabs are all useful pieces of lifting equipment that can make your construction project or warehouse management much easier. By understanding what each of these tools does and when to use them, you can ensure that your lifting tasks are completed safely and efficiently.
