Common Methods for Fixing Pig Stalls in Pig Farms

Depending on the installation site of gestation crate, fixing methods fall into two main categories: solid floor and slatted-floor (gap) installations. Below we analyze each type with case-based examples.

Solid Floor Installation
This method is straightforward. Foot plates of the stalls are not size-sensitive and are typically secured using external hex expansion bolts or plastic anchor bolts. M8×80 bolts are generally sufficient.

Slatted-Floor (Gap Board) Installation
For slatted floors, use T-bolts, nylon anchors, ground anchor bolts, etc. Below are several commonly used on-site fixing patterns for reference.

Rotating Foot Plate
The foot plate is separate from the stall leg during production and assembled on-site. Position the foot plate according to the slat gaps, then secure it by tightening the stall leg set screw against the rotating foot. This method is simple and usually requires only one bolt.

Standard Multi-hole Foot Plate
Multi-hole foot plates in lengths of 200, 240, or 260 mm fit most sites and can secure two bolts. In cases where two slatted boards meet or slat spacing is wide, a seven-hole plate usually ensures two fixing points. Narrow two- or four-hole plates often secure only one bolt and are not recommended. Two- or five-hole long plates under 260 mm rarely guarantee two bolt positions unless length is 300 mm or more. The symmetrical seven-hole “star” plate typically secures two bolts reliably, but higher cost makes it less common.

Continuous Flat Bar or Round Steel
Weld or bolt a continuous flat bar or round steel across the slats, then connect the stall foot to that bar. This yields a very secure fix and suits all slatted floors, but is relatively expensive.

U-shaped Bracket
Fix U-shaped brackets to the slatted boards, then bolt the stall foot to the U-bracket. This method is adaptable to various slatted-floor layouts.

Other Methods
Some installations use embedded anchors welded to the foot plates, commonly applied for stalls made from hot-dip galvanized tubing.

Regardless of design or fixing method, the sole requirement is secure, durable installation.
