ISO 11662-2:2014介绍了移动式起重机在静载荷下的结构能力试验方法。
本试验方法旨在提供一个系统的、无损的程序,通过使用电阻式电子应变计,确定在规定静载荷条件下起重机结构中产生的应力,并为规定的载荷条件规定适当的验收标准。
ISO 11662-2:2014适用于移动式建筑起重机
a) 钢丝绳支撑、格构吊臂附件或格构吊臂以及吊臂附件,
b) 绳索支撑、桅杆附件和桅杆安装的吊杆,以及吊杆附件,或
c) 伸缩臂附件或伸缩臂和飞臂附件。
移动式起重机制造商可使用ISO 11662-2:2014验证其附录E中所示移动式起重机类型的设计。
ISO 11662-2:2014 presents a test method for the structural competence under static loading of mobile cranes.
This test method is to provide a systematic, non-destructive procedure for determining the stresses induced in crane structures under specified conditions of static loading through the use of resistance-type electric strain gauges, and to specify appropriate acceptance criteria for specified loading conditions.
ISO 11662-2:2014 applies to mobile construction-type lifting cranes utilizing
a) rope-supported, lattice boom attachment or lattice boom, and fly jib attachment,
b) rope-supported, mast attachment and mast-mounted boom, and fly jib attachment, or
c) telescoping boom attachment or telescopic boom and fly jib attachment.
Mobile crane manufacturers can use ISO 11662-2:2014 to verify their design for the mobile crane types illustrated in its Annex E.
