Propalock, adjustable telescopic steel props, locking system, construction, safety, stability

Virtually all construction projects require temporary support - particularly those that involve an element of structural instability and partial demolition.

One of the most common ways of supporting structures in such projects is with the use of adjustable telescopic steel props. However this type of work is an area – identified by health and safety organisations worldwide in which a large number of accidents occur. Health and Safety organisations have also identified current practices relating to ‘temporary demountable structures’ within the events sector as potentially lacking management consistency resulting in a negative effect on safety.

Propalock is an innovative locking system, fitted to steel props, keeping them secure. Crucially, Propalock should only be operated by a designated site supervisor. This means unauthorised tampering with steel props is impossible – improving health and safety in the workplace.

Health and safety organisations have also identified current practices relating to temporary demountable structures within the events sector as potentially lacking management consistency – resulting in poorer safety.

Propalock is manufactured using engineering grade Polyamide 6 with 30 per cent glass fibre tiller. While preserving quality and strength, the resulting lower manufacturing costs enable mass volume production.

The lower cost, coupled with the product’s quality, will make Propalock more appealing to an ever more cost conscious construction industry. This in turn should lead to Propalock being adopted more readily, resulting in greater use and dramatically improving health and safety





In multiple incidents, including a Sheffield terrace collapse and a Fulham Road property accident, inadequate support and poor installation of props led to severe structural failures. These incidents underscore the critical importance of implementing reliable solutions like Propalock to prevent such accidents and ensure construction site safety.

Three-story terrace block collapsed in Sheffield

In Mach 2013, three people were left injured and around 20 made homeless after this three-story terrace block collapsed. The Heath and Safety Executive (HSE) found the central wall between 192 and 194 Block H1, Sheffield collapsed after the brothers responsible failed to put in place controls to support the building during modification works. The pair were jailed

Collapse of Two properties in Fulham Road, Westminster.

HSE Inspectors blamed poor installation and positioning of props for the collapse of these two properties in Fulham Road, Westminster.

The Buckinghamshire construction firm and its managing director were fined for multiple safety failings following the incident in January 2011

Building Collapsed in Ashton-Under-lyme

This building in Ashton-Under-lyme collapsed seconds after a worker dislodged just a few bricks from the exterior wall. According to the instillation of Structural Engineers It was caused by a lack of planning and the use of inexperienced contractors. With Propalock such an accident could have been avoided.

Support steel props holding up the ceiling at Queen Elizabeth Hospital have more than doubled.

The Queen Elizabeth Hospital in King’s Lynn faces structural challenges, with temporary support props more than doubling in four months to 470. They are installing “failsafe” props for safety, estimating a £190 million cost. The hospital received a “good” rating from the Care Quality Commission.

Father of five, lost his life when his own boat crushed him due to an unstable cradle.

Kevin Keeler, a father-of-five, tragically died when his sailboat fell on him during maintenance at Weymouth Sailing Club. The inquest determined it was an accidental death due to improper use of support props, leading to boat instability. The sailing club members expressed their condolences for his family.
