Jack Stands
Trailer jacks are a must if you’re servicing or unloading a trailer that is not connected to the tractor. Our range of industrial jack stands can stabilize or level a trailer up to 75,000 pounds in both single and paired units, helping also to prevent the trailer landing gear from sinking into soft ground. Jack stand signs alerting workers of the potential danger can be included to further enhance the safety of your operation.

Our Trailer Stabilizing Jack Stands are not cheap imports but are made to last. Features include Zerk fittings for constant lubrication, replaceable wheels and screw assemblies, and reinforced axles. Crane Stops are made for overhead bridge cranes, either for wheel contact or bumper contact.
- Class 2G Acme screw threads for a smooth fit and good support.
- Removable bushing to allow replacement of screw assembly.
- Swivel head tilts 9° to reduce side load bending force (except 4013-06).
- Zerk fitting provides uniform and constant lubrication of screw threads.

- A steel sleeve protects the axle.
- Spare parts always available.
- Powder-coated yellow finish.

Safe use of Jack Stands
- For proper support, use two (2) Jacks per trailer. A single Jack will not prevent side-tipping.
- The load Capacity of Jack must be equal to the gross weight of the trailer.
- If the driveway slopes, the load capacity is reduced due to side-load on the jack. Take this into account when using jacks.
- The trailer must be securely blocked (wheel chocks or dock-lock) when Stabilizing Jacks are used.
- Place Jacks on firm flat ground.
- Top plate of the jack must be in snug contact with the underside of the trailer.
- Aldon Jacks are designed to support semi-trailers. Do not use this product for any other purpose.
Always use two jacks per trailer.
Position jacks near the front corners of the trailer. Make snug contact with the smooth steel underbody on each side of the kingpin.
Do not install jacks on transverse floor beams of the trailer behind the kingpin.
Make sure the trailer is properly blocked before you install or remove stabilizing jacks. Don’t trust a cheap jack stand to hold a few tons of weight above your body or when loading trucks. Because trucks sit higher than most vehicles, jack stands need to be sturdy and secure against horizontal movement.
