Engineering properties of date palm to design a tree lifter/climber service machine

One of Iran’s most significant horticultural exports is the date fruit.
The automation of date palm plants requires an understanding of the properties of date palms.
The goal of this study is to examine the ‘Shahani’ date palm’s engineering characteristics.
The maximum crown height of the tree, which was determined by physical features independent of the tree’s age, was found to be 3.15 m, whereas the maximum trunk height was 23.32 m.
Without taking age into account, the greatest circumference was measured at the top, middle, and bottom to be 1.85, 2.5, and 2.6 m, respectively.
Experimental tests revealed that the trunk’s average flexural strength and flexural modulus were 269.467 and 6.917 Mpa, respectively.
In the parallel compressive strength test, modulus and stress were 293.9 and 4.829 MPa, respectively, whereas the average stress in the perpendicular compressive strength test was 1.124 MPa.
The hardness test’s average maximum load value was determined to be 0.767 kN. Designing tree climbers and lifters may benefit from these findings.
