Energy Consumption Structure and Its Improvement of Low-Lifting Capacity Scissor Lift

Abstract

The article presents the experimental investigation of low-lifting capacity hydraulic scissor lift energy consumption. The analysis is based on experimental tests of two individual drives of the scissor lift: the conventional one and the variable-speed electro-hydraulic one. The investigation focuses on the study of the total energy consumption for lifting and lowering the scissor lift with different masses of transported cargo and also power consumptions of each element supplying these systems. Particular attention was paid to the significant impact of power supply on each control component as the main factor of reduction in the energetic efficiency of the low-lifting capacity scissor lift. A comparison of both drives indicated that the mass of transported cargo has a significant influence on the choice of the drive used. Results of the research show that significant energetic savings are obtained, as the modernized propulsion system consumes 67% energy of the standard one. A decrease in the percentage of energy losses with the increase in the mass handled led to the conclusion that the enhancement of propulsion systems in scissor lifts should be especially considered in machines carrying big loads.

Type Synthesis Based on Modular Combination with Virtual Rotation Center and Application

“…Scholars have studied a series of devices for aerial working. The established aerial working platforms are divided into scissors lifting type [29,30], mast type [31], telescopic arm type [32][33][34], and mechanical arm type [35][36][37]. The mechanical arm type among them has attracted more and more attention due to its wide workspace and strong operability.…”

“…Experimental Verification of Performance. In order to verify the performance of the designed aerial work platform based on the modular combination type synthesis with VRC, the time of designed platform taken from one height to another was compared with that of the scissor-type [30] and mast-type [41] aerial working platforms. The results are shown in Table 1.…”

Energy Efficiency and Limitations of the Methods of Controlling the Hydraulic Cylinder Piston Rod under Various Load Conditions

“…Stawi ński et al [46], authors compare the energy consumption of a scissor lift with two individual propulsions. One is a typical hydraulic system with a throttle valve and the second one is the variable-speed electro-hydraulic system with a fixed displacement pump connected to a motor fed by a frequency inverter.…”

Conceptual Design And Prototype Production Of Innovative Hydraulic Walking Power Steering Controlled Scissor Lift Platform

“…For example, especially in the rail system vehicle sector, these mobile scissor platforms provide convenient transportation and assembly of various equipment during the wagon production stage. These mobile scissor lifts are also designed with multiple models, including manual, electric, and hydraulically driven [12][13][14]. Due to the light load, the steering control used in these models can be done manually.…”
