600kg Topwind Trailer Jack with 325 mm Travel | LF971-6032

Five Values That Define LF971-6032

Use the Published Endpoint Without Inventing a 475 mm Retracted Height

The product publishes 325 mm travel and 800 mm extended height. Subtracting those numbers gives 475 mm, but that result is not automatically a valid retracted-height specification unless both dimensions use the same engineering datum.

GOODIN'sTrailer Jack Selection Guide supports checking capacity, travel and installed-height references as separate selection inputs.

Powder Coating Is the Verified Finish—Not Red Oxide Primer

LF971-6032 is supplied with red powder coating. That wording should remain separate from LF900-2015B's Red Oxide Primer specification because primer-stage and powder-coated finish descriptions imply different purchasing questions.

No powder thickness, pretreatment, gloss, salt-spray duration or marine certification is supplied, so the page does not convert the color/finish description into a quantified corrosion-performance claim.

Check the Overhead Crank Envelope at the 800 mm Working Position

The Topwind handle places operator access above the jack. At the published 800 mm endpoint, nearby bodywork, guards or equipment may occupy the same vertical zone, so crank clearance should be verified in the completed trailer layout.

A Close Market Match Does Not Prove Telescopic or Weld-On Construction

Current 600 kg market products with almost the same 800 mm endpoint are often sold as telescopic, square-body or weld-on trailer jacks. Those similarities validate the commercial class, not LF971-6032's hidden construction.

GOODIN'sTrailer Jack Encyclopedia can help buyers compare common architecture families before the LF971-6032 drawing is reviewed.

Five Metric-Spec Items to Close Before Bulk Approval

1. Actual jack-position load: confirm the real vertical load against the published 600 kg capacity.
2. Height datum: obtain verified minimum/retracted and 800 mm extended reference points.
3. Mounting interface: confirm tube, bracket, flange, weld or bolt geometry from the model drawing.
4. Topwind envelope: verify handle radius and overhead access in millimetres.
5. Powder-coat requirement: define color tolerance, film thickness and corrosion test separately when contractual.

Questions Specific to LF971-6032

Production Visibility for OEM and Distributor Buyers

Trailer Support Applications Requiring a 600 kg Metric Jack and 800 mm Published Endpoint

LF971-6032 is intended for compatible applications where the actual vertical load, Topwind access and required working-height range fit its published metric specification.

The application must still be matched to the model-specific mounting interface and lower-height datum.

Use 800 mm as a Maximum Published Reference, Then Confirm the Lower Endpoint

For coupling, leveling or parked-support applications, obtain the actual minimum/retracted dimension from the LF971-6032 drawing. The 325 mm travel value alone does not define every mounting datum.

Reserve Overhead Crank Space Around Other Trailer Hardware

GOODIN's Utility-Trailer Upgrade List provides useful layout context for coordinating a jack with toolboxes, winches and other tongue-area equipment.

Match the Published Red Finish to the Buyer’s Actual Coating Specification

Red powder coating is the confirmed finish. Applications with contractual durability requirements should additionally define color tolerance, pretreatment, film thickness and corrosion-test acceptance.

GOODIN’s Materials & Manufacturing Insights provides broader context for coating and fabrication decisions.

Treat 600 kg as the Published Jack Capacity

The source does not define lift versus static/support capacity. Compare the actual vertical load at the jack position with the published capacity and verify the trailer-side structure independently.

Do Not Choose the Installation Method from a Similar 600 kg Jack

Current market products with almost identical capacity and 800 mm geometry are often telescopic and weld-on, but LF971-6032 mounting remains unverified. Request the exact model drawing before specifying frame integration.

Do not copy the 475–800 mm telescopic / weld-on construction of a market analogue into LF971-6032. Only the GOODIN model drawing or verified real product image can establish those structural details.
