Curtiss-Wright Industrial Division, which includes the legacy brands of Arens ControlsPenny & GilesPG Drives Technology and Williams Controls, is an excellent supplier in providing components and sub-systems which enable customer specific solutions for on- and off-highway vehicles. These include medium- and heavy-duty trucks, buses and motor coaches, construction and agricultural vehicles, materials handling, and other specialty vehicles, as well as sophisticated wheelchairs and scooters for medical mobility.

We are an excellent provider of electronic throttle controls, transmission shifters and sensors for commercial off-highway equipment and heavy trucks, so helping to address the long-term trend towards attaining higher fuel efficiency and lower emissions. We also supply operator controls and advanced motor controllers for hybrid and electric vehicles, such as buses, forklift trucks, pallet stackers, wheelchairs and rehabilitation chairs.

With a proud legacy spanning more than 85 years, Curtiss-Wright is a global innovative company that delivers highly-engineered, critical-function products and services to the commercial, industrial, defense and energy markets. Building on the heritage of Glenn Curtiss and the Wright brothers, we have a long tradition of providing reliable solutions through trusted customer relationships.

Standard Products or Custom Design

Many of our components can be specified straight from the catalog, with some items available from stock. This solution supports existing customers of standard products and can also aid the rapid evaluation of a technology when developing custom designs for OEMs.

Using our applications engi­neering expertise with your development team, we enable a free flow of ideas to provide the most reliable and cost-effective product solution to suit your unique application.

  • We have extensive hardware design expertise, with 3D modelling and rapid prototyping
  • We have in-house, experienced software design teams
  • We have in-house EMC test facilities in Europe and the USA
  • We have our own environmental testing facilities to enable vibration, shock, temperature, humidity, salt spray and other tests to be performed
  • We also have highly accelerated life test and stress screening (HALT/HASS) facilities to vali­date product reliability during development

Worldwide Presence

Curtiss-Wright Industrial Division has a global footprint, with design and manufacturing in the USA, the United Kingdom, China and India. This is backed by our own sales and technical support teams in the USA, Europe, China, India and Taiwan, with a network of representatives in other countries. 


Curtiss-Wright Industrial Division has a wealth of experienced design engineers entirely focused on key market products. Using the latest CAD/CAM tools for design and in-house facilities for extensive testing of mechanical and electrical parameters, Curtiss-Wright Industrial Division leads the industry across multiple market sectors.

Technology Development

Curtiss-Wright Industrial Division has a strategy to continuously research and develop new technologies, which can impact advanced operator controls and vehicle control systems. New technologies are fully developed and tested before being released for integration into product development programs.

Product Development  

We have established an excellent position in various markets by being highly responsive to specific customer requirements. Aligning this philosophy with state-of-the-art capabilities, such as rapid prototyping, our development centers are able to produce advanced components that are delivered reliably and on time.

We work in partnership with our customers to create innovative products. Whether it is customizing an existing product to better suit an application, or creating completely new concepts to address an OEM specification, our global team of engineers is ready for the challenge. Our engineers will work directly with your team to determine what is needed for a successful outcome. Combine this passion for collaboration with our extensive experience in a wide variety of market applications and Curtiss-Wright Industrial Division is well positioned to help your project succeed.

We understand that state-of-the-art solutions require state-of-the-art-tools and analysis. Here are a few of the systems and methods of analysis we implement when making your controls:

  • SOLIDWORKS® solid-modelling software
  • Product data management system
  • Finite element analysis
  • Non-linear and motion analysis
  • TolStack analysis – tolerance stack up analysis with Monte Carlo analysis for defects per million spring design software
  • MoldFlow from Autodesk® – ensure best practices before the model is sent to the toolmaker
  • FMEA Pro from Dyadem®
  • Risk analysis design and process
  • Agile Advantage® – Automated engineering change system, PPAP documents, quality documents
  • Altium® – electrical PCBA design and layout  

DFMEA:  Design Failure Mode and Effects Analysis

Curtiss-Wright Industrial Division design and manufacture safety-critical components. This is not a responsibility we take lightly, and have implemented formal processes to analyze each design for potential risks to the end operation.

  • Identify risks within the design or production of our product
  • All components of a design are analyzed for common failure modes with cross functional team
  • Identify the end effect and severity for the application
  • Identify methods of prevention or detection of the failure
  • Test plan created from DFMEA
  • Design changes may result from analysis
  • This document is continuously reviewed throughout product lifecycle.

We utilize analysis tools to predict performance of our products in the field. We also use analysis correlated to our laboratory test data to confirm design concepts. The following analyses and tools allow us to shorten the development cycle time and prevent repetitive testing:

  • Finite element analysis
  • Circuit simulation
  • Mold flow simulation
  • Design review with project management
  • Specification and regulatory review
  • Feasibility study
  • E-mark
  • Compliance testing SAE J1113, 72/245/EEC
  • REACH/ROHS/GADSL compliance in design and manufacturing
