1. A bend test apparatus for a hydraulic hose, the apparatus comprising:
a main rack,
at least one sliding rail extending in a longitudinal direction and a carriage which is directly joined to the at least one sliding rail and slidable on the at least one sliding rail in the longitudinal direction and which can be displaced by an actuator, wherein the actuator is a linear actuator,
wherein the apparatus further comprises a first fixture that is rigidly attached to the main rack to retain a first end of the hydraulic hose and a second fixture that is rigidly attached to the carriage to retain a second end of the hydraulic hose, the first fixture being fixed to the main rack and unmovable, the second fixture movable relative to the at least one sliding rail, wherein the carriage and the second fixture are both configured to be displaced toward the first fixture by the linear actuator; and
wherein the apparatus comprises a load cell that is attached between the carriage and the actuator, the load cell detecting a force applied by the actuator onto the carriage, the force applied to the carriage displacing the carriage in the longitudinal direction and bending the hydraulic hose.
