Study on dynamic characteristics and compensation of wire rope tension based on oil pressure sensor

open access: yesAdvances in Mechanical Engineering, 2019
The oil pressure sensors are installed on the hydraulic connection device to monitor the tension of wire ropes. The change of acceleration during the operation process of hoist causes the tension change of each wire rope.

CALCULATION OF SPECIAL HOISTING WIRE DEVICES WITH ELASTIC-PLASTIC LOADING

open access: yesSAFETY OF TECHNOGENIC AND NATURAL SYSTEMS, 2017
The article describes the use of hoisting wire devices (HWD) — parallel bunches of wire turns bonded by twisted ends on the outside. The calculation results of the bearing capacity of these HWD, taking into account elastic-plastic loading and safety requirements for their use, in which HWD wires strength assessment was conducted on tensile and bend ...

Research on Dynamic Characteristics and Compensation of Wire Rope Tension and Load Measurement Based on Hydraulic Connection Device

open access: yesShock and Vibration, 2019
During the operation of hoist, the speed and acceleration of each wire rope are inconsistent and the inertia force is changed due to the wear of the friction pad on the drum, which makes an impact on the cylinder of the tension balance hydraulic ...
