• Details

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. Constant displacement of crane are commonly used to need to reduce stress, such as the steam power plant boiler body, power plants, water, smoke, air ducts and burner, such as suspension parts, and in petroleum, chemical industry, where such support. When the thermal displacement of a certain lifting point in the pipeline system is greater than 12mm, it is advisable to use constant lifting to support it, so as to avoid dangerous bending stress and adverse stress transfer in the pipeline system.

Technical characteristics

Rated load: 0.2 ~ 400kN displacement: 0 ~ 508mm

Allowable field load regulation: plus or minus 10%

Technical parameters

The load deviation (including friction) specified in the full stroke is less than or equal to 6% When locked, it can withstand twice the working load.

The working principle of

The spring constant force support hanger is designed according to the principle of torque balance. It relies on sophisticated geometric design, make the load torque and spring torque balance all the time, in the process of work to maintain a constant supporting force, can eliminate or reduce the additional stress of piping or equipment.

The main and auxiliary spring constant force support hanger is designed according to the principle of constant net force under the action of main spring force and auxiliary spring force.
