Power Mechanical Folding Stairs

The Power Mechanical Folding Stairs versions of our FlowStep range are designed for use in environments where safe access folding stairs are used very frequently, where there is a concern to workers manual handling. Or where the system is too heavy for manual operation encouraging a safe working environment.

Built on the proven stability of the FlowStep range, the FlowStep Power Mechanical Folding Stairs add a rugged control panel that can be operated by workers, even while using PPE gloves.  A simple up/down lever is installed on the gantry or platform, and compressed air provides the power. So, a set of powered pistons raise and lower the folding stairs for tankers into place in seconds. Because, they are rated for outdoor use in temperatures ranging from -20°C to +80°C, the system is perfect for industrial applications worldwide.

Features and benefits

Adding power to the FlowStep range can make life easier and safer for operators, especially when adverse weather conditions make manual handling of equipment an increased risk. So, you can operate all FlowStep controls with gloved hands. The spring balance system ensures emergency back-up in case of air loss, guaranteeing safe operation and preventing tanker truck falls at all times. We have helped many customers add power to their folding stairs, as well as some where we have provided a solution on a site with folding stairs and loading platforms of various makes and ages. In addition, here are some more features and benefits:

  • Pneumatic power reduces manual handling
  • Enhanced control allows exact positioning
  • GRP control panel
  • Optional press down control
  • Suitable for hazardous area operation
