Support apparatus equipped with: - a support foot (15,15') of hydraulic kind that comprises: ∘ a cylinder equipped with a cavity axially shaped that has a longitudinal axis Z, ∘ a piston slidably received in a sealed manner in the cavity so as to divide said cavity into a first chamber and a second chamber, ∘ a stem provided with a first end fixedly connected to the piston and a second end that protrudes from the cylinder, ∘ a base fixed to the second end of the stem, and ∘ an actuation group of the support foot configured to selectively send a pressurised work fluid to the first chamber or to the second chamber so as to change the relative position of the base with respect to the cylinder, - a position sensor configured to monitor the value of a parameter indicative of the position of the base with respect to a reference element fixedly connected to the cylinder, - an electronic control unit, electrically connected to said position sensor, which is configured to transmit the value of the indicative parameter monitored by the position sensor to a remote device and to control the activation of the actuation group of the support foot (15,15') as a function of an activation signal and the value of the indicative parameter, the support apparatus being characterised in that it further comprises: - a tilt sensor configured to monitor the value of a parameter indicative of the angle of inclination of the support foot (15,15') with respect to a vertical axis and a horizontal axis, wherein the electronic control unit is configured to transmit the value of the parameter indicative of the angle of inclination to the remote device and to send an alarm signal to the remote device when the value of the parameter indicative of the angle of inclination is different from a preset value. - a support foot (15,15') of hydraulic kind that comprises: ∘ a cylinder equipped with a cavity axially shaped that has a longitudinal axis Z, ∘ a piston slidably received in a sealed manner in the cavity so as to divide said cavity into a first chamber and a second chamber, ∘ a stem provided with a first end fixedly connected to the piston and a second end that protrudes from the cylinder, ∘ a base fixed to the second end of the stem, and ∘ an actuation group of the support foot configured to selectively send a pressurised work fluid to the first chamber or to the second chamber so as to change the relative position of the base with respect to the cylinder, ∘ a cylinder equipped with a cavity axially shaped that has a longitudinal axis Z, ∘ a piston slidably received in a sealed manner in the cavity so as to divide said cavity into a first chamber and a second chamber, ∘ a stem provided with a first end fixedly connected to the piston and a second end that protrudes from the cylinder, ∘ a base fixed to the second end of the stem, and ∘ an actuation group of the support foot configured to selectively send a pressurised work fluid to the first chamber or to the second chamber so as to change the relative position of the base with respect to the cylinder, - a position sensor configured to monitor the value of a parameter indicative of the position of the base with respect to a reference element fixedly connected to the cylinder, - an electronic control unit, electrically connected to said position sensor, which is configured to transmit the value of the indicative parameter monitored by the position sensor to a remote device and to control the activation of the actuation group of the support foot (15,15') as a function of an activation signal and the value of the indicative parameter, the support apparatus being characterised in that it further comprises: - a tilt sensor configured to monitor the value of a parameter indicative of the angle of inclination of the support foot (15,15') with respect to a vertical axis and a horizontal axis, - a tilt sensor configured to monitor the value of a parameter indicative of the angle of inclination of the support foot (15,15') with respect to a vertical axis and a horizontal axis,
