The strain measurements and the calculations show that the dynamic load factor is not decreasing from the runway girder to the supporting structure, as it would be anticipated from DIN4132. From the analysis the maximum values of the dynamic load factors are obtained for lifting of the load ...
In additon,the mechanics model of the handstand mast lifting mechanism is established and analyzed ,and formulae of calculating dynamic load coefficient and friction between adjacent two guide posts are . 根据室内垂直升降作业的需求,结合国内外高空作业升降台的特点,分析了国内现有高空作业升降台的不足,...

firing of weapons, etc., as opposed to static loads. A dynamic load is equal to the apparent weight of the entire loaded aircraft. For example, an aircraft turning with 60° bank turn will experience a 2gforce, and the apparent weight of the aircraft, or its dynamic load, will be twice...
1. A method for dynamically measuring and indicating payload weight for a machine having at least one lift cylinder for elevating a payload carrier, including the steps of: lifting a load of known mass during a calibration operation; sensing a calibration lift cylinder velocity during said cali...
The shipyard is located on the Apuan coast in the Italian province of Massa-Carrara and the gantry crane has been a landmark there for decades. The gantry crane had a height of 46 metres and dismantling it involved lifting a load of over 1000 tonnes and a length over 105 metres and ...
2.A method according to claim 1 wherein the Stirling cooler is connected in a refrigeration apparatus having a storage chamber and configured for lifting heat from the storage chamber, the method further comprising detecting an operating frequency at which the electric motors consume a minimum electr...
The following fact has to be pointed out: it is less about the standardized size of dynamic factor and more about efforts to improve the dynamic process of cargo lifting, especially in the phase of unstationary movement. The purpose of this paper is pointing out the potential use of ...
A method for dynamically measuring and indicating payload weight for a machine having at least one lift cylinder for elevating a payload carrier is provided. The method includes the steps of lifting a load of known mass during calibrating and sensing a calibration lift cylinder velocity during calib...
DYNAMIC OPTIMIZATION OF A CRANE LOAD CURVE A method for controlling command of lifting a load suspended from a boom, carried by a mast of a crane, includes determining: depending on the mass of the suspended load, a specified load factor quantifying an acceptable exceedance with ... X Claeys...
