制动器是用于机构或机器减速或使其停止的装置,也可用作调节或限制机构或机器的运行速度。它是保证机构或机器正常安全工作的重要部件。履带式起重机(以下简称起重机)的制动器应满足以下要求:有足够的制动转矩;制动平稳;上闸、松闸动作迅速;受力构件有足够的强度和刚度;检查、维修、调整方便;磨损小、寿命长、工作可靠;外形尺寸小、质量轻。起重机提升用制动器的作用是防止悬吊的物品或吊臂下落。履带式起重机提升用制动器主要有带式和盘式2种型式。本文就其作用、功能、寿命和使用性能等方面作简单的比较。
Brakes are devices used to slow down or stop a mechanism or machine and also to regulate or limit the speed at which a mechanism or machine operates. It is to ensure the normal safety of institutions or machines an important part. Brakes for crawler cranes (hereinafter referred to as cranes) shall meet the following requirements: adequate braking torque; smooth braking; rapid braking on the gate and loose brake; adequate strength and rigidity of the stressed components; inspection, maintenance and adjustment Convenient; small wear, long life, reliable work; small size, light weight. The function of the crane lifting brake is to prevent the hanging items or jibs from falling. Crawler crane lifting brake with band and disc are two types. This article on its role, function, life expectancy and performance and other aspects for a simple comparison.
