Variable spring support hanger, is a household appliance. According to the installation form, this hanger can be divided into three types: the middle connecting suspension spring TH1, the upper and lower connecting suspension spring TH2, and the support spring TH3.
Constant force spring support hanger (hereinafter referred to as constant crane) is designed according to the principle of torque balance. The load moment and spring moment are always balanced with the allowable load displacement. For pipeline and equipment supported by constant crane, constant supporting force can be provided when displacement occurs, so no additional stress will be brought to pipeline equipment.
Design according to the principle of torque balance. The load moment and spring moment are always balanced within the specified range of load displacement. Therefore, the constant supporting force can be obtained when the pipeline and equipment with constant lifting support are displaced, which will not bring additional stress to the pipeline and equipment.
