Block and tackle - what is a block and tackle, how does a block and tackle (manual chain hoist) work?

What is a block and tackle?

A block and tackle, also commonly known as a chainblock or manual chain hoist, is a system comprised of two or more pulleys with a rope, cable, or chain between them. Block and tackles are typically used as a tool for lifting and lowering heavy loads.

In a standard block and tackle system, the chain is wound around two wheels. When the chain is pulled, it winds around the wheels and begins to lift the load that's attached to the chain.

Chainblocks can be attached to lifting slings or chain bags to lift the load more evenly.

 

How a block and tackle works

A block and tackle system is typically made up of a lifting chain, a hand chain and a grabbing hook.

First, the chainblock needs to be connected to the load via the grabbing hook. Then, when the hand chain is pulled, the chain tightens its grip on the wheel and forms a loop inside the mechanism - causing a tension which lifts the load from the ground.

This system can be used to lift loads manually, although electric block and tackle systems are popular because they require less physical exertion.

 

What can a block and tackle be used for?

Due to their lifting capabilities, block and tackle systems are commonly used in garages to remove engines from cars. Because they can be operated by one person, chainblocks are a wonderfully efficient way to complete lifting jobs which may otherwise have required two or more workers.

Block and tackle systems are also used on construction sites and on assembly lines.

Rigging equipment refers to the devices and elements used to lift and manoeuvre objects safely, as part of a planned system implemented by a team of riggers. This encompasses a variety of components which are used to secure and distribute the load in question, in order to facilitate the moving process and ensure that it is completed successfully. Industries which often require the services of rigging equipment include construction, engineering and event staging.

Like all lifting operations, hoisting and rigging should be performed with public and employee safety as a primary focus. In order to comply with health and safety legislation along with industry standards, organisations should carefully consider two following elements:

  1. Operation Planning: Before the lifting applications begin, teams should carefully consider the demands of the lift and conduct a thorough risk assessment. 

  2. Equipment: The first point will dictate how the rigging equipment is selected and used. Riggers must ensure that the overall rigging setup and individual elements are appropriate for the size and weight of the load in question, in order to avoid overloading the equipment, which can lead to damage and serious safety hazards. The rigging equipment itself should also be sourced from reputable suppliers, in order to ensure that the products are of a suitable standard and quality. In order to maintain this quality, the items should then be regularly tested to ensure that it continues to meet safety standards.

What is a Toe Jack?

It is often difficult to identify every item in a workshop especially if they look similar to another, which is why it is important to understand the importance of each tool before working in this environment. Today we will be looking at the Toe Jack and what the purpose of this tool is.

What is a toe jack?

toe jack (also known as a floor jack) is a heavy-duty piece of equipment that is designed to lift items with very low or high clearances. Toe jacks are ideal for moving loads that are lower down on the floor, such as heavy machinery. They are available in a variety of different weight capacities too, making them suitable for a wide range of operations.

The 'Toe' is the fork-like part at the front of the Toe Jack which slots underneath the load you wish to lift. Loads can also be lifted by the 'head' part of the Toe Jack, which can sustain even heavier loads from higher clearances. The hydraulic pump is then used to lift the load to the required height and if your Toe Jack includes a swivel feature, this will allow you to place the load in the correct position.

Here at SafetyLiftinGear, we stock Hydraulic Toe Jacks, meaning water pressure is used to lift the loads. Available in both standard and swivel models, you should be able to find a Toe Jack to suit you. Our Toe Jacks are also available to hire if you need one for a single occasion. Simply click the 'Hire me' button and then 'Enquire' at checkout to receive a quote for this rental. 

What is a toe jack used for? 

A Toe Jack is commonly used to lift and lower heavy loads onto moving skates. This operation means heavy loads can be moved around with ease. If it is an exceptionally heavy load, multiple Toe Jacks can be used at once if required. Toe Jacks are most often used to move heavy machinery in a warehouse, but can also be used for operations such as moving furniture too. The varied weight capacity of Toe Jacks means they can be the helping hand you need in a variety of operations.

If this sounds like something that might be useful for you, then feel free to browse our comprehensive range of Hydraulic Toe Jacks. If you have any queries about this product, please do not hesitate to get in touch or call us on 0808 123 69 69.

confined space

What is a Confined Space?

A confined space is a work area which is considered to be partially or substantially enclosed, restricting movement. In many cases, confined spaces will also present restrictions in terms of entry and exit, increasing health and safety risks for workers who perform operations in these areas.

Confined spaces are often defined as areas that are:

  • Enclosed on all sides
  • Small/Difficult to work in
  • Hard to get out of

However, a place not usually fitting this description may become a confined space if the conditions change, for example, if the level of oxygen is reduced or there is water present. This may also apply if the area is used to store specific items such as gas cylinders, which would present a risk to the surrounding atmosphere if discharged.

Work Areas Commonly Defined as Confined Spaces Include:

  • Tunnels
  • Pipelines
  • Manholes 
  • Silos
  • Tanks
  • Pits
  • Sewers
  • Trenches
  • Storage Bins
  • Ductwork
  • Shafts 
  • Building Voids

What Does the Law Say About Confined Spaces?

Under the Health and Safety at Work Act 1974, employers must ensure the safety of their workers and others, a duty which is regulated in further detail by the Confined Spaces Regulations 1997. These regulations require the employer to avoid confined space entry where possible, following safe working systems in cases where the work is unavoidable. If confined space work is being conducted, employers must ensure that emergency arrangements are put in place before commencing operations.

In addition to the specific requirements of working in confined spaces, regulations for managing health and safety at work (1999) also require employers/self employed individuals to carry our a thorough risk assessment of the area, in order to accurately identify which measures need to be taken in order to prevent injuries. This may result in the need to manage certain hazards by using specialised equipment such as safety barriers and harnesses.

What Hazards do Confined Spaces Present?

One or more of the following risks must be present or reasonably foreseeable for the area to be defined as a confined space:

  • Reduced oxygen 
  • Fire and explosions 
  • Harmful gases, fumes and vapours 
  • Solid or liquid materials flowing into the space
  • Increased temperatures 

 When is a Confined Space not Defined as a Confined Space?

If an enclosed space does not present one of the specific risks outlined by the regulations, it may not be defined as a confined space, but will be subject to other relevant regulations relating to workplace health and safety.
