How to measure the HHXG Chain electric hoist

How to measure the HHXG Chain electric hoist

1, inner / outer chain sheet deformation, cracks, corrosion.

2, the pin is not deformed or rotated, corrosion.

3, roller whether cracks, damage, excessive wear.

4, the joint is loose and deformation.

5, if there is no noise or abnormal vibration, HHXG Chain electric hoist lubrication condition is good or not.

Chain length precision measurement method:

A, HHXG Chain electric hoist before the measurement after cleaning.

B, HHXG Chain electric hoist will be tested around two wheels, the measured HHXG Chain electric hoist on both sides should get support.

C, HHXG Chain electric hoist before the measurement should remain in applying the three 1min 1 of the minimum ultimate tensile load condition.

D, measurement, measurement of load applied rules in HHXG Chain electric hoist, the HHXG Chain electric hoist, the upper and the lower sides of tension. HHXG Chain electric hoist on the sprocket should ensure the normal tooth.

E, the two sprocket center distance measurement.

Measurement of HHXG Chain electric hoist extension:

1, as the removal of the entire HHXG Chain electric hoist clearance, to pull the tension applied to some extent in the HHXG Chain electric hoist measurement.

2, measurement, in order to minimize the error, in section 6-10 (link) of the local measurement.

The medial and lateral L2 L1 size between the roller 3, measuring the pitch number, in order to judge the size of L= (L1+L2) /2.

4, to calculate the elongation length HHXG Chain electric hoist, use this value and the limit of HHXG Chain electric hoist elongation value contrast.

Elongation of HHXG Chain electric hoist = judgment dimension benchmark length / standard length *100%.

The reference length =HHXG Chain electric hoist pitch * section number.
