ANALYSIS OF LIFTING MECHANISM OPERATION OF HOISTING MACHNIES

Vestnik of Kazan State Agrarian University, 2015
The lifting mechanism of hoisting machines is presented as a compound-chain mechanism, parts of which perform different movements. In the study this mechanism is replaced by a two-tier mechanism, equivalent to the action with the real scheme. Based on the principles of theoretical mechanics, theory mechanisms and Dalamber principle, we received a model

A hoisting mechanism of clamshell cranes with a planetary gear train

Machines, Technologies, Materials, 2021
Clamshell cranes are hoisting machines (machines with cyclic action) designed for handling bulk materials. The name of these cranes comes from the load gripping device – clamshell grab. In addition to the clamshell (two-jaw) grab for bulk materials, there are grabs designed for long-size and single loads. In the case of high-productivity bulk materials

Multi-Objective Optimization Design for Body Hoist Mechanism of Mining Dump Truck

Advanced Materials Research, 2012
The rear multi-stage cylinder direct-acting hydraulic body hoist mechanism is widely used in mining dump truck. The working principle of the body hoist mechanism is introduced. The dumping process is simplified through the introduction of “dumping line” and the variation of ore mass and hoist torque are analyzed. The optimization design of the position
