Ship electricity experimental device,Crane hydraulic tr--ning device

I. Overview

The crane is a tire -type basic vehicle as the carrier with the work device and the manipulation of the crane equipment and the manipulation mechanism. Also known as a crane, a type of crane is lifted and handling machinery. The hydraulic crane is a self -consisting of tire -type basic vehicle with a carrier -loading equipment work device and operating mechanism. It is a widely used equipment in engineering machinery. Construction road construction, hydraulic engineering, national defense engineering and other industries. The hydraulic experimental table has the advantages of small size, light weight, convenient operation, and long -distance manipulation. The purpose is to guide students to carry out positive thinking, innovative design, and cultivate students' comprehensive design ability and practical hands -on ability.

2. Equipment composition

1. It is m--nly composed of components such as the crane tr--ning table, hydraulic pumping station, hydraulic element and various control devices, and programmable controllers (PLCs).

2. The tr--ning table and tr--ning desk are iron double -layer sub -light -densely spraying structures.

3. It can simulate various actions of the real -heavy machine working device. The hydraulic system uses an imported transparent machine glass hydraulic element and a transparent nylon hose. The structure and working principle of the hydraulic component, and the working principle of the hydraulic circuit at a glance. The entire tr--ning table has the advantages of image, intuitive, convenient, and reliable.

4. Equipped with a full -time hydraulic element: Each hydraulic element is equipped with a installed bottom plate, which can be placed on the aluminum alloy panel with convenient and randomly and at will (the aluminum alloy profile structure of the panel with the "T" groove formation). The oil circuit is overlapped with a fast conversion. It is convenient for disassembly and does not leak oil.
