Yale Reliant™

Forklift accident avoidance with the help of technology

Warehouse safety is a critical challenge. Let technology share the burden and help you to avoid forklift accidents.

Yale forklift equipped with Yale Reliant technology is continuously monitored for stability to help prevent tip overs

Forklift stability support that doesn’t overcorrect

When Yale Reliant intervenes, it does so carefully – not with abrupt shifts or jerks that can upset stability.  
The technology continuously measures the combined center of gravity of the lift truck and load it carries. When a potential risk is detected, it determines the appropriate degree of performance adjustment to respond with, taking into account the forklift speed, acceleration, travel direction, steering angle, mast tilt and load weight, height and position.

    Helps maintain overall stability and minimize potential for tip overs


    Adaptive forklift speed control

    Adjusts truck speed, acceleration or deceleration to maintain lift truck stability and help avoid potential tip overs in certain scenarios:

    • Reduces speed while cornering or making sharp turns with a heavy load
    • Smoothly manages acceleration or deceleration when a load is raised or laden forks are tilted
    • Controls fork tilt to limit potential for load sliding off forks in tight spins or other maneuvers like pulling product from high racking

    Adaptive fork and load control

    Automatically adjusts lift functions to minimize the potential for product damage, tip overs and excess stress on truck components:

    • Controls lift and lower speed changes to avoid slamming fragile products down
    • Manages mast speed to avoid movements that cause it to sway
    • Limits mast tilt speed and range when a load is in an unfavorable position
    • Manages tilt to avoid sharp stops that could upset stability
    • Controls reach extension and retraction to avoid sharp movements and stops
    • Restricts lift functionality if a load exceeds truck’s rated capacity

    Detects obstacles and helps operators avoid potential impacts


    Object detection

    Reduces truck speed in response to any obstacles that are detected by LiDAR sensors monitoring the path of travel. This increases operators’ response time, enabling them to steer around obstructions or come to a stop, helping avoid potential impacts with:

    • Equipment
    • Pedestrians
    • Debris
    • Racking
    • Other obstructions

    Proximity detection

    Helps increase operator situational awareness to hazards beyond their field of view and provide additional time to react. It limits truck performance in response to ultrawideband (UWB) badges detected in the monitored area, including:

    • Another UWB-equipped truck
    • A pedestrian wearing a UWB badge, even if obscured by aisles of racking
    • UWB beacons placed in high-traffic zones to enforce lower speed limits

    End-of-aisle slowdown

    Proactively reduces travel speed of the truck at the end of an aisle before entering main throughfares, which may help reduce avoidable damage.


    Fork height restriction

    Limits truck travel speed and mast lifting speed until the operator has lowered the forks beneath the designated threshold or the truck exits the height-restricted zone. This helps promote operator awareness of low clearance areas to minimize the risk of damage to the truck and facility infrastructure such as:

    • HVAC equipment
    • Conveyors
    • Sprinklers
    • Low-hanging beams
    • Signage
    • Doorways, tunnels and stairwells

    Exclusion zones

    Proactively reduces travel speed to discourage operators from moving through designated areas of the facility, such as those dedicated to:

    • Other purposes, like hazardous materials storage
    • Workers, including pedestrian-only zones

    Forklift speed control zones

    Helps promote correct operator behavior and minimize risk of pedestrian impacts by proactively limiting truck travel speed in designated locations like:

    • Heavily populated areas
    • Crosswalks

    Exception zones

    Mutes proximity detection-based performance reductions that would otherwise apply, enabling the truck to remain at full performance in selected locations:

    • Tight aisles where trucks cannot maintain the minimum distance that they could in larger thoroughfares
    • A badged pedestrian is nearby, but on the other side of a wall or barrier
    • Trucks are alongside other trucks but are engaged on a wire
