手动液压叉车设计

摘  要

 
叉车装卸搬运物品，是物流中最常用的工具（图下）。本设计从国内外市场范围内，介绍叉车的发展变化及叉车的结构造型，了解手动液压叉车设计的重要数据：根据液压叉车的工作环境和自身特点，设计叉车的车身长度及跨距，并保证工作时的起重量，工作时保证上升时从最低位置到最高位置的高度达到工作要求。手动液压叉车设计是根据客户的生产需要提供的参数及工作环境审设计。同时具体数字还应根据国家规定的标准或制造商标准来确定，同时要考虑要求设计制造的厂商自身技术水平。所以，现实工作中应当充分调查，权衡双方细致协商和慎重决定。
关键词：叉车，机构原理，重量。
 
 

ABSTRACT

The forklift truck loading/unloading goods, is the most commonly used tools in logistics (figure below). This design from domestic and international market scope, introduces thedevelopment and change of the forklift truck and the structure of the forklift truck modelling, understand manual hydraulic forklift truck design according to the important data: hydraulic forklifts working environment and its own features and design of the body and the span length of the forklift truck and ensure that work, to guarantee the weight up from the lowest to the highest position the height of the position to work requirements. Manual hydraulic forklift truck design according to the customer's production is the need to provide the design parameters and working   environment. At the same time the detailed Numbers also should according to the standards set by the state or manufacturer standard to determine, at the same time to consider to ask design and manufacture of manufacturer's skills. So, the reality of the work shall be fully survey, of both parties through consultations and careful meticulous decision.
Keywords: forklift, the organization principle, weight.
