How do mobile scissor lifts with outriggers secure the outriggers to the ground?

Jul 15, 2025

Mobile scissor lifts with outriggers typically secure the outriggers to the ground using mechanical force and friction, rather than physically anchoring them into the ground. Here's how the securing process works:
Methods Used to Secure Outriggers on Mobile Scissor Lifts:
1.Hydraulic or Screw Jack Pads
Each outrigger has a jack or stabilizer leg with a base plate.
These legs are manually or hydraulically extended downward until the base pads press firmly against the ground.
This downward force lifts the wheels slightly off the ground, transferring the weight and ensuring stability.
2.Friction from Large Base Plates
The wide, non-slip base plates at the bottom of the outriggers increase surface area and grip.
These plates are often made from high-friction materials or coated with anti-slip pads to prevent sliding.
3.Self-locking Mechanisms
Outrigger jacks often include locking mechanisms (e.g., pins or valves) that prevent unintentional retraction after deployment.
This ensures that the lift remains level and secure during operation.
4.Leveling Indicators
Many mobile lifts are equipped with bubble levels or electronic tilt sensors to guide the user during outrigger deployment.
Proper leveling ensures that the outriggers are evenly secured and stable.
Important Notes:
They are not bolted or anchored to the floor like fixed equipment.
For use on soft or uneven surfaces, outrigger pads (e.g., thick plastic or metal plates) may be placed under the outriggers to distribute the load and prevent sinking.
Proper deployment on firm, level surfaces is critical to maintaining lift stability.
