Calculating, by the central device, a number of missed messages.

A lifting vehicle comprising: a frame carrying a front axle and a rear axle; carrying a pair of front wheels and a pair of rear wheels, respectively; a lifting boom articulated in a rear section of the frame; and a stability control system configured to control the conditions of operational stability of the vehicle, wherein said stability control system comprises: a first and a second load sensor configured to provide information about the loads acting on the front right wheel and on the front left wheel and an electronic control unit programmed for: calculating a transverse dimension of the position of the center of gravity of the vehicle according to the values provided by said first load sensor and said second load sensor.

A method and apparatus to regulate the use and removal of freight. The apparatus includes a sensing element, a stoppage element, and at least one actuator. The sensing element is operable to determine the presence of freight. Stoppage element can alternate between a first condition configured to impede freight removal and a second condition configured to permit freight removal. The presence of freight maintains stoppage element in the first condition absent engagement of the at least one actuator and engagement of the at least one actuator switches stoppage element to the second condition when freight is present.

An automatic guided vehicle comprising a fork carriage with a fork, a propulsion drive system, a sensor to acquire position data of objects located in a detection field and a computer. The vehicle comprises a reference member located in the detection field of the sensor rigidly secured to a common rigid frame with the sensor. The sensor periodically acquires control position data indicative of a position of the reference member. The computer periodically compares the control position data with a reference value stored in a memory.

A method and a system for collision avoidance in a hazardous area (4) of a logistics facility (2) that includes determining a first distance (14) between a stationary hazardous area monitoring apparatus (30) disposed inside the hazardous area, and a first sending and receiving apparatus (13) that disposed on an industrial truck (10, 11, 12) and connected to a control system of the industrial truck, and determining a second distance (24) between the stationary hazardous area monitoring apparatus and a second sending and receiving apparatus disposed on a movable object. A determination is made as to whether the first distance and the second distance are less than or equal to a predeterminable intervention area distance (6), and a collision avoidance action is carried out if both the first distance and the second distance are less than or equal to the predeterminable intervention area distance.

The invention relates to a machine (1) for handling loads (24), comprising: —a frame (2) equipped with a driving station (15), —a load handling system (4) carried by the frame, a device (6) for controlling the load handling system (4), wherein this control device (6) that can be manually actuated by an operator comprises a manual part (61) configured to be manually grasped, —a control unit (5), the control unit (5) being configured to receive control signals from said control device (6), —a member (7) for activating the manually actuatable control device (6), wherein the control unit (5), in the actuated state of the activating member (7), is configured to authorize the control of the handling system (4) as a function of at least the control signals received from the control device (6), characterized in that the driving station (15) is equipped with a detection system (16) for detecting a presence or absence of the operator at said station (15), this detection system (16) comprising at least one presence sensor (17) distinct from the control device (6), and characterized in that the control unit (5), in the non-actuated state of the activating member (7) and after passing from the actuated state to the non-actuated state of the activating member (7), is configured to prevent or authorize the control at least of the handling system (4) with the control device (6) at least as a function of the absence or presence status of the operator detected by the system (16) for detecting a presence of the operator at said station (15).

The vehicle includes a load bearing portion, a counterweight, a stability control system and a controller. The counterweight is mounted on the load transport vehicle along a longitudinal axis of the load transport vehicle. The counterweight is configured to counter a first moment generated by a load carried by the load bearing portion. The first moment causes the load transport vehicle to rotate along a first vertical plane perpendicular to a ground on which the load transport vehicle rests or is driven. The first plane is parallel to the longitudinal axis. The stability control system is mounted on the load transport vehicle. The stability control system is extendable along the longitudinal axis to counter a second moment causing the load transport vehicle to rotate along the first vertical plane.
