Alley Mat Max Grip
The Animat alley mat Max Grip tested here, an elastic floor for walking ways in cubicle houses, was investigated with regard to durability and comfort properties on test stands in the DLG Approved Test. The deformability and elasticity, the abrasion resistance, the slip resistance, the cleaning distance were measured and a permanent tread load was applied. The deformability and elasticity in new condition and following permanent tread load were better than standard.

Alley Mat Max Grip
The Animat alley mat Max Grip tested here, an elastic floor for walking ways in cubicle houses. Black rubber mat
The deformability is measured in new condition and following permanent tread load with a round steel foot (diameter of 105 mm and therefore a contact area of 75 cm²) and a penetration force of 2,000 N (corresponding to approx. 200 kg).
The permanent tread load is measured on a test stand with a round steel foot in the standard test programme with 250,000 alternating loads at 5,000 N (corresponding to approx. 500 kg). The steel foot is adapted to the natural conditions as an “artificial cow foot”. The foot has a diameter of 105 mm and therefore a contact area of 75 cm²; the carrying edge of the hoof is simulated by a 5 mm wide ring on the periphery of the sole that projects 1 mm above the rest of the surface.
In a standardised abrasion test with 10.000 cycles the top cover was grinded with an emery cloth (granulation 280) and a grinding pressure of 500 N (= 8.1 N/cm2 surface pressure). The friction element was cooled continuous with water to prevent an influence of the generated heat during the abrasion test. The size of the grinded area was 61,5 cm².
The measurements were carried out with the ComfortControl test rig of the DLG test centre. A loaded (10 kg) round plastic foot (105 mm diameter, with a contact area of 75 cm², 3 mm wide ring at the periphery of the ground) was pulled with a velocity of 20 mm/s across the mat.
In test stand trials with a high pressure cleaner (approximately 145 bar, exposure period 1 minute with a 25° flat jet nozzle and a coarse dirt remover) the distance was measured where no damage occurs.
In the penetration test in new condition with a round steel foot (artificial cow´s foot) having a diameter of 105 mm (contact area 75 cm², with a 5 mm wide ring at the periphery of the sole, which projects 1 mm over the rest of the surface (carrying edge of the claw)) and a penetration force of 2.000 N (corresponding to ca. 200 kg), penetration depth was 2.3 mm. This results in a calculated surface pressure of 26.7 N/cm². Elasticity was measured after the Max Grip mat had been exposed to a permanent tread load exerted by the steel foot (250.000 alternating loads of 5.000 N). After the endurance test, the penetration depth of the mat stays at 2.3 mm (see Fig. 2).
Evaluation: Deformability and elasticity
– in new condition +
– following permanent tread load +
After the Max Grip mat had been exposed to a permanent tread load exerted with 250.000 alternating loads of 5.000 N (corresponding to ca. 500 kg), the mat showed no noticeable wear. Lasting deformation could not be observed.
no lasting deformation +
no noticeable wear ++
The abrasion depth after 10,000 cycles amounted to 5.5 mm, this corresponds to approximately 26 % of the mat thickness. Of the ground surface 26.1 grams were rubbed off.
The abrasion depth and the slight grit implicate a satisfactory wear resistance of the mat ◯
The slide pulling tests showed a good slip resistance on the dry or wet mat surface in new condition. The measured friction coefficients (μ) all surpassed the minimal value of μ = 0.45 which speaks for a good foothold.
Good slip resistance on dry and wet rubber mat surface +
In test stand trials with a high pressure cleaner damage to the mat only occurred when a minimum distance of 40 cm (with a coarse dirt remover) and 20 cm (with a flat-jet nozzle) was not kept.
For cleaning and disinfection of the floor cover, only the cleaning agents permitted by the manufacturer should be used.
– 20 cm with a flat jet nozzle ◯
– 40 cm with a coarse dirt remover ◯
Based on test-stand investigations, the criteria tested in this DLG Approved Test evaluate the comfort and durability properties of the Animat Max Grip alley mat for use in the walking ways in cubicle houses. The tested Animat Max Grip alley mat met the requirements of the Testing Framework with respect to the investigated criteria.

A quality mark “DLG-APPROVED for single value-determining criteria” is awarded to agricultural products which successfully passed a smaller-scope DLG usability test according to independent and recognized evaluation criteria. The test intends to highlight special innovations and key criteria of the test item. The test can focus on criteria from the DLG testing framework for full tests or on other individual features or qualitative criteria. The minimum requirements, the test conditions and procedures as well as the evaluation guidelines of the test results are determined in consultation with a DLG expert group. They comply with the generally recognized technology rules as well as with scientific and agricultural knowledge and requirements. The successful test concludes with the publishing of a test report and the awarding of a quality mark which is valid for five years following the award date.
The DLG Approved Test “Deformability/Elasticity, Permanent Tread Load, Abrasion, Slip resistance, Cleaning distance” includes technical measurements on test stands of the DLG Test Center. The deformability and elasticity,the abrasion resistance, the slip resistance, the cleaning distance were measured and a permanent tread load was applied. The test was based on the DLG Testing Framework for elastic stable flooring, as at April 2015. Other criteria were not investigated.
