SL-TJ-03 Ratchet Trailer Jack With 6 Inch Load Spreading Beam
SL-TJ-03 is the only jack in the range that spreads its load along a beam rather than through a single cap. A 6 inch beam sits across the front of the trailer, and a wheel barrel frame with 8 inch rear and 4 inch front wheels lets one person steer 180 lb into position.
Product Overview
What This Product Is and Where It Fits
The 6 inch beam is what sets this model apart. Instead of concentrating the reaction under one 8 inch cap, it distributes it across the front of the trailer. That matters on older trailers and on any frame where a point load under the nose is not welcome.
The frame is a wheel barrel design: two larger wheels at the rear and a single smaller wheel at the front, so the jack is steered rather than shoved. At 180 lb it is the heaviest jack in the range and that frame is what makes the weight workable.
Lifting capacity is 40,000 lb, delivered through a ratchet screw lift. A ratchet gives more mechanical advantage per stroke than a spin head, which is the right trade when the jack is being used to raise rather than only to hold.
Service range is 39.5 through 51 inches, the same as SL-TJ-02 and SL-TJ-04, so a yard can mix models without changing its working practice.
Key Benefits
Three Reasons Buyers Specify This Line
Spreads the reaction across the trailer front
A 6 inch beam instead of a single cap, which suits older frames and repeated use on the same trailer.
Steered, not shoved
The wheel barrel frame with 8 inch rear and 4 inch front wheels gives one operator directional control over 180 lb.
Ratchet lift for load, not speed
More advantage per stroke than a spin head when the jack is actually raising a nose.
Application Scenarios
- Raising the front of a trailer where a point load is unwelcome
- Older trailers and frames with no dedicated jacking pad
- Workshop lifting during landing gear work
- Yards that move one jack between many trailers
Who It Is For
- Fleets running mixed-age trailers
- Workshops that lift the same trailers repeatedly
- Operators who want steering control over a heavy jack
Problems It Solves
- Point loading under a trailer nose on an older frame
- Heavy jacks that cannot be steered into position
- Not enough mechanical advantage to raise a settled nose by hand
- Jacks that have to be lifted rather than wheeled

CertificationsCertification Status
No third-party certification is published for SL-TJ-03 Ratchet Screw Trailer 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
- Steer the jack into position using the barrel frame rather than lifting it
- Seat the 6 inch beam squarely across the trailer front before taking load
- Work the ratchet in short even strokes and watch the beam contact as load comes on
- Lower fully and check the ratchet releases cleanly before wheeling the jack away
