Definition of pitch, roll, and roll

♦   The "Allowable Moment Load" and "Moment Rigidity" in the specifications are digitized into the components shown in the figure below. Please refer to the corresponding ingredients according to the conditions of use.

 

Axis Definition

GMT has defined different axis as the following figuration according to the movement direction:

Horizontal movement direction is X and Y axis.

Vertical movement direction is Z axis.

Movement around X, Y, Z axis is defined to α axis, β axis, and θ axis.

Green arrows present the specified axis movement direction.
