SL-TJ-05 Heavy Duty Trailer Jack With 16 Inch Wheels
SL-TJ-05 is the top of the S&L jack range: the highest lifting rating at 50,000 lb, the largest wheels at 16 inches and the tallest service range at 41 to 55 inches. It is the model for yards where the surface is rough and the trailers sit high.
Product Overview
What This Product Is and Where It Fits
The 16 inch wheels are the reason to choose this jack over SL-TJ-04. Wheel diameter, not weight, decides whether equipment crosses a broken yard, a rail flange or a drainage channel, and 16 inches rolls over obstructions that stop an 8 inch wheel dead.
The service range is different from the rest of the range too: 41 through 55 inches rather than 39.5 through 51. That extra 4 inches at the top covers high-deck and drop-frame trailers that the other models reach only with packing.
Ratings are 100,000 lb static and 50,000 lb lifting, the highest lifting figure S&L publishes, through the same two-way ratchet and 2 inch diameter screw as SL-TJ-04.
Net weight is 173 lb. Unlike the 180 lb SL-TJ-03 it is not on a steered barrel frame, so the large wheels are doing the work of making that weight manageable.

Application Scenarios

Problems It Solves

CertificationsCertification Status
No third-party certification is published for SL-TJ-05 Heavy Duty Two-Way Ratchet 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.
