Abstract
The paper presents the hydraulic system for the operation of a lifting platform in two constructive variants. One of the drive schemes is with energy recovery. A hydraulic, energy and economic analysis is performed for the two proposed drive schemes using the numerical simulation technique. The conclusions are useful in design and exploitation. The platform can be used for various applications in agricultural farms or construction.
Highlights
Lifting of loads in industry and agriculture is possible with different machinery, some of which are commonly called nacelles or lifting platforms
These fixed or mobile platforms are designed for specific works such as dressing trees cutting vineyards, harvesting fruit on orchards, etc. or handling large loads view of them storage or distribution
The pump no longer supplies flow, and due to the weight of the platform, the oil in the lifting cylinder piston chamber passes to the tank through the proportional distributor (5) and through the throttle (8) to adjust the speed to the descent
Summary
Lifting of loads in industry and agriculture is possible with different machinery, some of which are commonly called nacelles or lifting platforms. In agriculture, these fixed or mobile platforms are designed for specific works such as dressing trees cutting vineyards, harvesting fruit on orchards, etc. Handling large loads (bales of fodder, bags of cereals or fertilizers etc.) view of them storage or distribution. They can be used by people with reduced mobility, for easy access to different institutions. It is recommended that the primary energy source be made up of a set of electric batteries at the expense of the polluting thermal engine; In this case, reducing consumption leads to extending the operating time between 2 battery charging and reducing the power consumption of the batteries
