Alabama Administrative Code › Title 535 - ALABAMA MANUFACTURED HOUSING COMMISSION › Chapter 535-X-13 - REGULATIONS FOR THE INSTALLATION OF MANUFACTURED HOMES AND MANUFACTURED BUILDINGS AND THE MANUFACTURE OF GROUND ANCHORS AND TIEDOWN DEVICES › Section 535-X-13-.09 - Standards For The Manufacture Of Anchor And Tiedown Devices

Current through Register Vol. 42, No. 9, June 28, 2024
(1) All
					manufacturers of ground anchors and tiedown devices must have the approval of
					their products by the Alabama Manufactured Housing Commission before offering
					their products for sale and use within the State of Alabama.
(2) All anchors and tiedown devices used in
					the State of Alabama for the purpose of anchoring a manufactured home or
					building to the ground must be tested by a third party independent testing
					agency, recognized by the Commission as having the technical background and
					experience in testing ground anchors and tiedown devices. The third party
					agency cannot have any interest or ties with the manufacturer which the agency
					is testing. There can be no conflict of interest between the agency and the
					manufacturer.
(3) All anchors and
					tiedown devices shall be tested to a minimum of 4,725 lbs. The combined
					vertical displacement attributed to the elongation of the anchor and withdrawal
					from the substrate shall not exceed 2" at an applied load of 4,725 lbs. Anchors
					tested with loads applied at an angle to the anchor shaft shall not displace
					the anchor more than 3" horizontally at an applied load of 4,725 lbs.
(4) Anchors designed for connection of
					multiple ties must be capable of resisting the combined loads placed upon such
					anchors. The displacement cannot exceed 2" vertically and 3"
					horizontally.
(5) All tiedown
					devices shall be tested with the same loads as the ground anchors. Failure of
					the tiedown devices and ground anchors shall be considered as breakage, bending
					or slippage that results in excessive yielding at 2" vertically and 3"
					horizontally at an applied load of 4,725 lbs. or with combined loads.
(6) A complete product description shall be
					provided for each anchor and each tiedown device tested and submitted for
					approval. The information shall include the following:
(a) Manufacturer and model identification:
					Each model shall show model identification and shall be permanently marked
					indicating the conditions under which such anchor or device has been approved.
					For traceability, the identification marks of all anchors, components, straps,
					and devices used for anchoring and tying down manufactured homes must be
					visible after the anchor or device is installed.
(b) Detailed drawings including all
					dimensions (i.e. shaft, flute, head, etc.)
(c) Grade of steel or complete description of
					material used for anchor.
(d)
					Methods of securing tiedown device to the anchor.
(e) Methods of securing device to home
					including all buckles, crimps and bolts required.
(f) Method of installing anchor in
					ground.
(g) Special requirements
					for protecting the anchor against frost heave where applicable.
(h) A written detailed description of the
					quality assurance program and its procedures. The program shall include areas
					of material compliance and dimensional adherence to the engineered drawings,
					traceability of incoming raw materials, control of manufacturing methods,
					random and individual inspection of finished goods, and periodic testing to
					assure 95-98 percent compliance to program standards. Periodic test results are
					to be filed with the Commission office.
(i) Drawings shall bear the seal of a
					registered engineer (structural-mechanical) registered in the state of
					manufacture or the State of Alabama.
(j) Each model must be field tested and
					certified for holding power in the bottom half of the soil classifications
					adopted by the Commission. All tests must be conducted with representatives of
					the Alabama Manufactured Housing Commission present when the tests are
					performed.
