Bespoke Engineering Design Solutions

At Allan J Hargreaves Plant Engineers, we provide professional engineering design services tailored to the specific requirements of the rail, plant, lifting, and industrial sectors. Combining extensive industry experience with advanced 3D CAD technology, we develop innovative, practical, and safe engineering solutions that help our clients improve performance, reduce operational risks, and meet regulatory requirements.

Whether you require a completely new design, modifications to existing equipment, or support for a specialist engineering project, our team can deliver a cost-effective solution from concept through to implementation.

Advanced 3D Design and Engineering Analysis

Using industry-leading 3D design software, we create detailed engineering models that allow clients to visualise solutions before manufacture and installation. This approach helps identify potential challenges early in the project lifecycle, reducing costs, minimising downtime, and improving overall project outcomes.

Our design capability includes:

  • Full 3D CAD design and modelling
  • Concept development and design optimisation
  • Detailed manufacturing drawings
  • Reverse engineering of existing equipment
  • Design validation and risk reduction
  • Mechanical system and component design
  • Structural assessments and verification

To further enhance design reliability, we can carry out Finite Element Analysis (FEA) to evaluate structural performance under operational loads. This enables us to identify stress concentrations, improve structural integrity, and ensure equipment performs safely and efficiently in demanding environments.

Proven Engineering Solutions

Our engineering team has successfully delivered a wide range of bespoke projects across the rail and industrial sectors. Examples include:

Direct Rail Wheel Braking Systems

Design and development of specialist braking systems to improve operational safety and performance in rail applications.

ALO Slew Limitation Systems

Custom-engineered solutions to control and restrict slew movement, helping operators maintain safe working limits and comply with operational requirements.

OLE Height Limitation Systems

Design and implementation of overhead line equipment (OLE) height limitation systems to reduce the risk of infrastructure strikes and improve operational safety within rail environments.

Safety Engineering and Risk Assessment

Safety is a critical element of every design project. Alongside our mechanical and structural design services, we provide specialist engineering assessments to support compliance and risk management requirements.

Our services include:

  • Failure Mode and Effects Analysis (FMEA)
  • Machinery risk assessments
  • Functional safety assessments
  • Safety-related control system design
  • Risk reduction strategies
  • Technical documentation and compliance support

We can assess and design Safety-Related Parts of Control Systems (SRP/CS) in accordance with BS EN ISO 13849, helping clients achieve the required performance levels while ensuring machinery and systems operate safely and reliably.
