An optical hazard detection system is described that may be used with an aerial device. The optical hazard detection system is utilized for determining a hazard in proximity thereto. The system comprises an optical sensor and a controller. The optical sensor is configured to capture optical images. The controller is configured to acquire the optical images from the optical sensor. The controller is also configured to identify a hazard at least in part from the optical images and to establish a hazard zone to prevent the utility platform from striking the hazard. The hazard zone is within a deployable range for the aerial device.

A sensor arrangement for securing a monitored zone having at least one hazard zone with respect to a machine is provided, wherein the sensor arrangement has at least one optoelectronic monitoring sensor for detecting objects in the monitored zone and has a control and evaluation unit that is configured to compare the positions of detected objects with the hazard zone and to initiate a safety-relevant response of the machine in the case of a dangerous position. The control and evaluation unit is furthermore configured to generate and to monitor a further hazard zone with respect to a detected object.

A vehicle rear warning system includes: a driving information detection portion that collects information measured from a radar and a camera sensor in a reverse mode of a vehicle; and a controller that separates a danger zone and a safe zone with reference to a fixed obstacle at a rear of the vehicle by performing fusion of the information measured from the radar and the camera in the reverse mode of the vehicle, and generates a collision event and controls warning and braking when a moving object approaching from the danger zone is detected, while limiting the warning and braking for a moving object existing in the safe zone.

Applicant provides an offset safety winch bar to remove the handle portion of a winch bar from a hazard zone created by the offset angle of the winch bar for safety in winching strap spools attached to flatbed trailers. An offset safety winch bar includes a spool insert insertable into a flatbed trailer winch spool hole; a body connected to said spool insert; and a handle connected to said body, wherein said spool insert is at an offset angle from said body, and said body has one or more compensating angles to intersect a portion of said handle with the longitudinal axis of said spool insert. The compensating angles can place the longitudinal axis of said handle aligned upon the longitudinal axis of the spool insert.

The invention relates to a concrete pump, comprising: —a frame; —a supporting leg, the supporting leg having a supporting foot, the supporting foot being extensible relative to the supporting leg; and—a drive for driving a movement of the supporting leg relative to the frame. A camera image of a hazard zone around the supporting leg is produced by a monitoring sensor. The drive is controlled by means of a remote control. The data information is transferred to the remote control via an interface. The invention also relates to a method for supporting a concrete pump. On the basis of the received data information, it can be determined, by means of the remote control, whether the movement of the supporting leg causes a hazard.
