Order Download Introduction During the excavator design, we need to consider several key factors, such as the special demand of the market, noise and emissions regulations, reducing costs while improving performance. In a mini excavator, for example, the powertrain consists of a diesel engine which is hooked up to a set of hydraulic pumps. Together, they generate the critical gallons per minute (gpm) of hydraulic fluid that energize the undercarriage, cab swing, bucket curl, attachment operation and everything in between.
Research on the control strategy of power train systems for hybrid
The electric excavator's powertrain system — provided by Danfoss Editron, a subsidiary of Danfoss Power Solutions — eliminates the noisy, dirty diesel engine in the 323F and replaces it with a battery pack and electric motor to power the excavator's hydraulic system. To enhance the energy saving efficiency, this paper proposes an innovative electric hybrid hydraulic excavator, as shown in Fig. 1. The engine, electric motor/generator, invertor, battery, hydraulic pump, and planetary gear are installed in the powertrain of the excavator. The hydraulic motor and generator are installed in the return line of. The new 16-ton wheeled excavator and 30-ton crawler excavator feature an electric powertrain in place of the diesel engines typically used to power these machines. Included in the electric powertrain are several Danfoss components, including a permanent magnet motor from Danfoss' Editron division. A Danfoss controller is used to for control. The powertrain solutions that integrates the engine, hydraulic parts, controller, to provide customers with system solutions. Dual-pump design and Integral valve design, make the excavator structure compact, performance excellence. LSC hydraulic system, distribute according to demand, manoeuvrability better handling. Nr.

This paper systematically analyzed the performance of the powertrain hybridization of hydraulic excavator and compared the main performance among the parallel, the series and the conventional configurations based on a 5-ton excavator. The data of the conventional excavator used for analysis were gathered from the real working process, while. The main factor for low efficiency and high emissions of the traditional excavator is the low efficiency of the power train system. 1 Currently, the main method of improving the efficiency of the power train system is hybrid power train systems (HPTSs). 2 - 4 The HPTSs adopt two or more power sources to drive the load 5 - 7 and to make full use. This article reviews the state-of-art for the hybrid wheel loader and excavator, which focuses on powertrain configuration, energy storage devices, and energy management strategies. The basis of classification and characteristic of each powertrain configuration are described. Advantages and disadvantages of batteries, supercapacitors, hydraulic. Currently, there are several energy saving methods for HE and they mainly concentrate on the following three aspects: (1) improving the performance of working components; (2) reforming the hydraulic system; (3) ameliorating the situation of power matching between the diesel engine, the hydraulic system and the load.

Turner Powertrain Systems is a leading provider of quality ready-to-run products, engines and components offering initial affordability, reliability, simplicity of use and maintenance, as well as responsive support. Skilled engineers collaborate with OEMs to create transmissions specifically designed for machines to deliver optimum performance. To reduce the energy consumption and emission, an innovative powertrain and the energy management strategy are proposed for hydraulic excavator in this paper. The novel powertrain consists of the engine, motor/generator, planetary gear, gearbox, and variable hydraulic pump. The energy regeneration system is also applied on the system to regenerate the potential energy and charge the battery.
When you need to cycle through large loads, the PC8000 has you covered. It was designed with input from mining operations around the globe to maximize productivity with 240-400 st trucks. Customizable for your operation. Rigorously engineered for durability. Sustainable, efficient Tier 4 Final engine. In the series-parallel hybrid powertrain configura-tion of an excavator, the engine drives the generator directly. The hydraulic pumps are driven by generator in series, and the swing electric motor is driven by gen-erator and battery or supercapacitor in parallel.31 Although the fuel consumption of series-parallel hybrid

This paper presents an innovative powertrain design and an energy regeneration system for hybrid hydraulic excavators to reduce energy consumption and emissions. The proposed system is designed to maximize engine efficiency and make full use of the energy gained from boom and arm retraction. The powertrain features an innovative design that incorporates a continuously variable transmission. Electric power train system is one of the energy saving technologies of excavator [3], [4], [5]. However, because of cost and reliability of batteries, the development of electric excavators is restricted.
