A safety system for a load carrying machine including: a controller, a location sensing arrangement in electronic communication with the processor, the location sensing arrangement configured to determine a location parameter of a load, a monitoring arrangement, the controller configured to receive the location parameter and determine a projected area of the load and control the monitoring arrangement to focus on the projected area to monitor the projected area.

A crane for lifting and transporting loads includes a handling element, for supporting and handling the loads, and a chassis for transferring the loads of the crane onto a support surface by a contact arranged in contact with the surface, such as wheels. A drive transmission, such as a drive wheel, moves the crane on the support surface. The drive transmission is capable of translating relative to the chassis to adjust the force exerted by the drive transmission upon the support surface. The crane includes a sensor for detecting the force exerted by the drive transmission upon the support surface; and a control unit configured for adjusting the position of the drive transmission relative to the chassis, based on the detection of the sensor.

Provided is a crane (1) including: a boom (7); a wire rope (8); a winch (9); and a hook (10). The crane further includes: a spooling operation instrument (24) for enabling commanding an operation state of the winch (9); and switches (switch (41) or switch (42)) for enabling commanding a switch of a control mode with regard to the operation of the spooling operation instrument (24). When the boom (7) is in a flat travel orientation with the hook (10) loaded on a prescribed site (hook platform (12)), the switches ((41), (42)) being in an on state and the spooling operation instrument (24) being operated toward one side thereof cause the boom (7) to be raised to a work orientation while the wire rope (8) is unwound such that the hook (10) is not lifted.

An apparatus for managing a construction site comprises a memory storing sensor data received from a plurality of capture devices associated with the construction site. The memory stores one or more rules or thresholds. A processor is configured to process the sensor data by evaluating at least one of the rules, or by comparing a prediction computed from the sensor data with at least one of the thresholds. The processor is configured, in response to evaluation of a rule, or in response to comparison of a prediction with a threshold, to trigger an alert.

A crane includes a crane main body, a boom, a jib, a boom driving unit, a jib driving unit, a manipulation unit, a drive control unit, a suspension device, a determination unit, and an operation regulating unit. The determination unit determines whether a jib boom angle condition is established or not. The operation regulating unit allows the crane to change a posture between a fall posture and a work posture according to a determination result of the determination unit.
