HySecurity MX4195, Spring, Lift
The HySecurity MX4195 lift spring is part of the HydraWedge SM50 mechanical assist system. A properly matched lift-assist spring helps balance the movement of the wedge plate and can reduce stress on the hydraulic drive components and scissor linkage. If the spring is weak or damaged, the system may lift unevenly, move more slowly, strain the hydraulic pump pack, or create extra load on pivots and bearings. This is a heavy mechanical component, so service should be handled carefully with the wedge safely supported and stored energy accounted for. When replacing the spring, inspect the strut pin, bushings, scissor-joint bearings, and surrounding linkage for wear.

Technician Note
This is an OEM-style HySecurity replacement part. Similar-looking HySecurity parts may differ by operator family, generation, voltage, harness length, handedness, or mechanical position. Use the original part number and the operator parts diagram as the final fitment check.
Before Ordering Checklist
- Confirm the HySecurity model and operator family.
- Match the full part number, including any suffix.
- Compare the original part location, connector, hardware, and mounting style.
- Check surrounding parts for wear or damage before replacing only one component.
- For hydraulic, high-load mechanical, or electrical repairs, use a qualified gate technician.
Professional Advisory
Gate and barrier equipment can move with significant force and may contain stored mechanical energy, hydraulic pressure, or live electrical circuits. Do not bypass safety devices, guards, sensors, or interlocks. If the system has uncontrolled movement, missing guards, damaged wiring, hydraulic leakage, or uncertain compatibility, stop operation and have the equipment inspected by a qualified technician.
Product Questions and Answers
What does the MX4195 lift spring do?
It provides lift-assist support for the HydraWedge SM50 mechanism, helping balance the wedge movement and reduce load on related components.
What are the listed specifications for MX4195?
Common product references list MX4195 as approximately 4.25 x 18 x 0.56 inches with a 200 lb/in force rating.
Is MX4195 a universal compression spring?
No. It should be used only where the HydraWedge SM50 parts diagram calls for MX4195.
When should this spring be replaced?
Replace it if it is broken, weak, damaged, corroded, or if lift-assist service shows the original spring no longer performs correctly.
Is spring replacement a DIY repair?
This is a heavy mechanical component in a wedge system. Service should be handled by a qualified technician with the mechanism safely supported.
