Handling machine with telescopic arm

A handling machine comprising:

• a telescopic arm including a first section and a second section mounted to slide into the first section;
• a telescopic ram configured to displace the second section in relation to the first section;
• a hydraulic actuator system coupled to the second section of the telescopic arm;
• and
• a hydraulic control circuit including a hydraulic pipe system extending at least partially inside the telescopic arm and attached to the hydraulic actuator system to supply the hydraulic actuator system;
• wherein,
• the telescopic ram includes
• a ram body mounted fixedly in relation to the first section and
• a ram rod mounted to slide between a retracted position in the ram body and an extended position,
• the hydraulic pipe system includes at least one flexible hydraulic pipe that extends inside the telescopic arm and includes
• a first portion fixed in relation to the first section,
• a second portion fixed in relation to the second section, and
• a U-shaped third portion connecting the first portion and the second portion to one another,
• the concavity of the U-shaped third portion is oriented toward a distal end of the first section,
• the distal end is opposite a proximal end of the first section,
• the proximal end defining an opening, and
• the second section extending into the opening such that when the ram rod is actuated from the retracted position to the extended position, the U-shaped third portion moves along an external part of the ram rod of the telescopic ram extending out of the ram body of the telescopic ram.
