The gear installation of 8 ton gantry crane
First, use feeler to measure side mesh clearance of gear, the minimum value should meet related standards. If take pressure lead method, lead galvanized iron wire along the outer gear, the cloth length is not less than five pitch. Rotate the gear, after the gear presses galvanized iron wire flat, then take out the iron wire, use the micrometer to measure the thickness of flatten iron wire, the minimum value should meet related requirement.
Second, take red staining method to check and measure the meshing condition of gears. The specific steps are as followings, daub the red color on both sides of the small gear surface thinly and evenly, rotate the high-speed shaft and make big gear rotate towards positive and negative directions, then check the contact trace, calculate the contacting percent, the value should conform to relevant standards.
Third, open-gear has the same installation way, the contacting precision can low 1 level to 2 level.
Never make cable stayed or lift sliding
The operator can’t make cable stayed or lift sliding, namely wire rope must be through the center of lifting material and straight. Cable-stayed or lift sliding is very dangerous, it may lead overload, produce inertia force and harm the operator. Even the wire rope may be broken. Operator must obey the rules and operate in correct way, this can protect operator’s safety and prolong the service term of crane.
