constant support hanger

Detailed introduction

Constant force spring hanger (hereinafter referred to as the constant crane) is designed according to the principle of torque balance.The load torque and spring torque are always in balance with the allowable load displacement.For the pipe and equipment supported by constant crane, a constant supporting force can be provided when displacement occurs, so additional stress will not be brought to the pipe equipment.

Technical features

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

Allowable field load regulation quantity :±10%

Ii. Main technical parameters:

Specified load deviation (including friction) within full travel :≤6% average load deviation within full travel and design load deviation :≤2%

When locked, can withstand 2 times the maximum working load.

Structure composition and working principle

The spring type constant force support hanger is mainly composed of cylindrical spiral spring and lever mechanism.Because its spring and component manufacturing technology is simple, mature, the product performance is stable, the economy is good, has been used for a long time in the domestic, therefore is the most widely used type;The performance of constant force hanger with butterfly spring is relatively difficult to control, while the main and auxiliary spring constant force hanger requires high precision of spring, so it is difficult to manufacture, so it has not been widely used

Application

Constant hangers are used for piping and related components where higher levels of vertical travel occur. Their job is to transfer the working load over the whole travel area while keeping it constant, i.e. without any considerable deviations. The functional precision of the constant hangers is decisive for favourable long term behaviour of the components involved.
