Height and slew limiters / restrictors are commonly fitted to excavators working in environments where safety margins are tight. They help prevent unplanned movements that can damage infrastructure, equipment, or put people at risk.
A height limiter allows the operator to pre-define a max working height. The system hydraulically prevents the machine from exceeding that height. A slew limiter allows the operator to pre-set the swing range so the machine cannot swing past defined hold points. Bucket crowd limiters provide similar control for oversized attachments to reduce the risk of crowding too far and causing damage.
BGS Hydraulics specialises in the supply, installation, and commissioning of approved height and slew restrictors and bucket crowd limiters.
Machine types we support
BGS Hydraulics supplies a range of systems to help manage machine operating limits, lifting capacity and restricted work zones.
Our base system, Mobile Height Limiters Sydney, is a proven solution for controlling boom height and slew movement around overhead services, structures and site exclusion zones.
For more advanced applications, BGS is the sole Australian importer of Railics and Helics Rated Capacity Indicator systems from Europe. Commonly known as RCIs or Load Moment Indicators, these systems provide greater control over machine functions, lifting capacity and operating limits.
Railics is purpose-built for road-rail excavators undertaking lifting work. It can provide rated capacity monitoring, height, slew and area limiting, virtual walls, attachment-specific load charts and live operator information through an in-cab touchscreen.
It is suited to projects where machine configuration, rail cant, slope, slew position and attachment setup all need to be considered.
Helics is designed for standard civil excavators carrying out lifting or high-risk attachment work. It provides rated capacity limiting, load monitoring and height limiting, with optional slew and area limiting, virtual walls and attachment-specific load charts.
Both systems can be configured around the machine, attachments and site requirements.
BGS supplies and installs height and slew limiters, restrictors and bucket crowd limiters for excavators and specialist plant.
A height and slew limiter controls machine movement within set boundaries. An RCI system adds rated capacity monitoring, load information and, where configured, machine control functions that help prevent operation outside defined limits.
Mobile Height Limiters Sydney is suited to practical movement control. Railics is designed for road-rail excavators, while Helics is suited to standard civil excavators requiring advanced lift and load monitoring.
We can supply components and provide installation support depending on the machine type and site requirements.
We can work with your team to understand the site requirement and recommend suitable options. Final compliance obligations remain with the site and machine owner.
Common excavator and plant platforms. Share your make, model, and year so we can confirm.
It depends on the machine, access, and system type. We will provide an estimate once we understand the scope.
