Erecting machine commissioning steps
(1) Check the coupling parts are firmly linked.
(2) Check the electrical wiring is correct.
(3) Check whether the leakage each part of the hydraulic system.
(4) Check the mechanical and structural part has wiring.
(5) Check the rotating parts lubrication.
(6) Check the oil level in the tank meets the requirements, and test run the hydraulic system.
l injection of 32 hydraulic oil to the tank through the fuel tank filler neck on the (old as the 20th grade)
l Different grades of different varieties of hydraulic oil cannot be mixed with the hydraulic oil filter in the course of a year.
l Completely loosen the relief valve, power, turn the pump, empty running at no load. Observe the pump rotation is correct, of surveillance, such as the functioning of the pump without noise, air operation for 5-10 minutes;
l Rotation (or sliding) manual valve and relief valve properly tightened, so Jack started, then at full stretch 4-5 times reciprocating stroke cases. Exclude air as much as possible within the system;
l Manual valve in the manipulation of change cannot be too fast to when the action, too fast, forward movement should go back to stay in the middle position by moment, in order to avoid hydraulic shock phenomenon (and even more so when there is a load operation).
After the above inspection and adjustment, after confirming normal test run as follows:
A car near the two legs after lifting back to put away the front leg, measuring girder cantilever deflection, meets the requirements;
B if A satisfies the requirements, the front legs to fall in place, adjust the machinery to normal, you can do the heavy lifting test. Hoists must be within the specified range. It can also be used as a precast girder hoist. Allow lifting trolley hoists repeatedly walking 2-3 times. The method is the heavy lifting - stop - drop - stop, repeated several times, and then use the lifting beam vertical shift - Stop - Back - Stop, repeated several times, be sure to use the rear brake can be put into safe and reliable.
After the completion of the no-load and load test, check all mechanical, mechanism, hydraulic and electrical part has an exception, if normal, can be put to use.
