AML500 Base Plate - Socket, Spigot

AML500 base plates fix the foot of an AML500 leg or tower to a concrete footing. Each is a 700 mm square, 25 mm 5083 aluminium plate with four 76.2 x 6.35 mm SHS chord stubs welded on, their tops machined as a module end with the same taper-reamed holes. Four Ø22 mm holes at the corners, on a 600 mm square, take M20 anchors (supplied by others), and a drain hole under each stub lets water out.

The socket base (AP-AML500-BP-SK) takes a node directly, bolted with an AP-AML500-JK-MN joint kit, or a module, joined with an AP-AML500-JK-MM kit as at a module joint. The spigot base (AP-AML500-BP-SP) comes with four joint spigots fitted and bolted in its stubs, so a module slides straight on and bolts up with an AP-AML500-JK-MN kit. Both put the joint 250 mm above the footing, so the lattice in the leg stays on the 500 mm grid from the ground up.

Anchors and footings are engineered for each project.
