SL-TJ-02 Wheeled Trailer Jack With Spin Top Screw Head
SL-TJ-02 doubles the static rating of the carried jack and adds a published lifting capacity. It rolls out to the trailer on 10 inch semi-pneumatic wheels and is wound up by a spin top screw head, which is faster to operate than a ratchet for the same travel.
Product Overview
What This Product Is and Where It Fits
Two ratings are published for this jack and they mean different things. 100,000 lb static is what it holds once set. 40,000 lb lifting is what it will raise. A jack used to lift a settled trailer nose must be chosen on the lifting figure.
The 10 inch semi-pneumatic wheels are the largest on any of the screw models in the range. Wheel diameter is what decides whether a 110 lb jack rolls across a yard or has to be dragged, and 10 inches clears the kind of surface break found at the edge of a concrete apron.
A spin top screw head gives continuous rotation rather than the short strokes of a ratchet. Over a 12 inch travel that is a meaningful difference in the time an operator spends at the trailer nose.
The 8 inch top cap spreads contact under the trailer frame. Service range is 39.5 through 51 inches.
Key Benefits
Three Reasons Buyers Specify This Line
A published lifting rating, not just a holding one
40,000 lb lifting capacity alongside 100,000 lb static, so it can raise a settled nose rather than only support one.
Rolls on 10 inch wheels
The largest wheel in the screw range, which is what makes 110 lb manageable across a yard surface.
Spin top head instead of a ratchet
Continuous rotation covers the service range faster than a ratchet lever over the same travel.
Application Scenarios
- Drop and hook yards where jacks move between trailers
- Raising a settled trailer nose before coupling
- Dock bays where trailers are loaded without a tractor
- Workshop use during landing gear repair
Who It Is For
- Yards where one jack serves many trailers rather than staying with one
- Operations that need a lifting rating, not only a static one
- Sites with a yard surface that punishes small-wheeled equipment
Problems It Solves
- Jacks too heavy to reposition without a second person
- Small wheels that stall at an apron edge or a drain channel
- Ratchet operation that takes too long over a full service range
- Using a stabilising-only jack where a nose actually has to be raised

CertificationsCertification Status
No third-party certification is published for SL-TJ-02 Wheeled Trailer Stabilising Jack in S&L's own documentation, so this page marks it TBC at quotation rather than implying one. For a jack the evidence that matters is the static and lifting rating, and both are published for this model. If your specification also requires a test certificate for the delivered batch, say so before the order is placed.

Use Guide
Getting It Right On Site
- Roll the jack to the trailer nose and set it on firm ground clear of the landing gear
- Spin the head until the 8 inch top cap is seated squarely under the frame
- Take the load gradually and check the column stays plumb
- Wind fully down before rolling the jack away so the screw is not carried extended
Questions
SL-TJ-02 Wheeled Trailer Stabilising Jack Questions
Can this jack lift a trailer or only hold it?
Both ratings are published: 100,000 lb static and 40,000 lb lifting. Use the 40,000 lb figure when the nose has to be raised.
What is the service range?
39.5 through 51 inches.
How much does it weigh?
110 lb.
Why a spin top head rather than a ratchet?
Continuous rotation covers the full service range faster. The ratchet models suit positions where an operator needs more mechanical advantage per stroke.
What size are the wheels?
10 inch semi-pneumatic, the largest on the screw models in this range.
