    摘要： A lifting load and tipping moment detecting device for a mobile crane for detecting a lifting load and a tipping moment with high accuracy, thereby making it possible to use an excessive load prevention system effectively while ensuring safety. For this reason, sensors (50, 48, 46) are provided for detecting the boom length, boom angle and shaft weight of a boom hoisting cylinder (26) on the side of a second boom (28), respectively, and a controller (38) is also provided for operating a lifting load (Wa) suspended from the second boom (28) based on signals from those sensors. In addition, a boom length sensor (44) and a boom angle sensor (42) on the side of a first boom (24) are provided for operating a tipping moment.

    摘要： The invention provides a cooling fan driving device and the a fan rotational speed control method using the device capable of reducing uneconomical waste of flow volume of pressurized oil discharged from a hydraulic pump when the rotational speed of a cooling fan is increased to the target rotational speed. The target rotational speed of the cooling fan is set at a target rotational speed setting portion 22 of a controller 7 based on temperature of refrigerant and hydraulic oil and the rotational speed of an engine. An acceleration pattern for increasing the rotational speed of the cooling fan to the target rotational speed is set at an acceleration pattern setting portion 23 based on the rotational speed of the cooling fan, the target rotational speed set at the target rotational speed setting portion 22, and magnitude of force due to inertia of the cooling fan and the hydraulic motor which drives the cooling fan. The rotational speed command value calculation portion 24 performs control so that pressurized oil is supplied to the hydraulic motor at a flow rate required when the hydraulic motor is controlled to be accelerated based on the acceleration pattern. Thus, it is possible to reduce relief flow volume to be wasted without being consumed for the acceleration control of the hydraulic motor.
