Hydraulic boom system for vehicle

A hydraulic boom system for use on a vehicle, the hydraulic boom system comprising:

• a boom having a first end receiving a work platform, and a second end, opposite the first end;
• a fixed component fixedly mountable to the vehicle;
• a rotary component, rotatably mounted on the fixed component about a vertical axis;
• a spacing penetrating downwardly at least partially through the fixed component, around the vertical axis;
• a pivotal component, pivotally mounted to the rotary component about a horizontal axis, and receiving the second end of the boom;
• a raising hydraulic cylinder between the pivotal component and the rotary component to raise and lower the boom by pivoting the boom about the horizontal axis, the raising hydraulic cylinder having a first end connected to an upper pivot made integral to the pivotal component, between the horizontal pivot axis and the work platform, and a second end connected to a lower pivot which is made part integral to the rotary component, the second end extending downwardly inside the spacing.

• a hydraulic power unit having a hydraulic fluid tank and an electric motor driven hydraulic pump connected to the hydraulic fluid tank;
• and
• an electrical cable having a coiled portion housed in the fixed component and coiled around the vertical axis, extending upwardly from the coiled portion and connecting the electrical motor at a first end thereof, and having a second end opposite the coiled portion connectable to an electrical power supply located at a fixed position relative to the vehicle.
