balancing tower crane
1), only after the disengagement foot tower slewing ring tail plate, can be balanced.
2) Push the joystick to the pump station "jacking up" direction, lifting up until the slewing ring just left foot until fishplates.
3) Check the tower crane is balanced, you can trim the tractors were necessary.
4), whether in a vertical line can be found by checking the exact location of the car pulling slewing bearing legs and fishplates. Jacking is also shown by the pressure gauge on the pump station the minimum pressure required to be verified.
5), you can pull the car boom boom equilibrium position in the abdominal oblique tie rod cloth as a marker, but note that the marker distance depends on the length of the boom, boom and therefore different lengths, mark distance should also be different.
<2>, lifting Canada Day
(1) Notes
a) Check the standard section cited beam is solid, the car is safe and flexible.
b) Check the hydraulic original station is installed, the oil tank is charged, and then turn to debug and test.
c) Check whether lifting beams under riding stable.
before d) observation tower machine after balance before lifting.
e) In the lifting process, the absolute prohibition of rotary movement of the tower crane, luffing trolley for luffing movement and hoisting winch mechanism for lifting or lowering operation.
f) tower crane lifting, in addition to its own to install the required lifting, but not allowed to carry out other lifting job.
g) tower crane lifting should be done when the wind is less than four.
(2), lifting Canada Day
1), part of the tower from the top of the tower with a pawl support in the last section of a standard lifting ear seat, piston rod is almost fully extended throughout the trip, the guide wheel sets of shelves can not exceed the tower the fixed part.
2), the standard section to the tower. Introducing sets rack.
3), the hydraulic system lever into "lift" position, the pawl from jacking ear seat. Steering lever pawl from the tower.
4) The hydraulic system lever into "down" position, so that the standard section insert fish plates, with a pivot pins, safety pins and cotter pin locking standard section. Lift the hinged ladder supreme fixed end of the connector into the lower escalator escalator ends following a standard section.
5) Loosen the four bolts to introduce the car in the standard section and sets its launch aircraft.
6) The second criterion Festival hanging on the rail, in the meantime, you must be from the top of the tower crane department from being associated with the lower section of the tower.
7) To this end, the hydraulic system lever into "down" position until the slewing ring foot (1) is connected to the last section of a standard fishplates.
8) mounted above the four safety pins to replace the pin. If necessary, trim the weight down, the tower crane standard section hook rack to hang onto the hook pulley block, will install another standard section channels linked to the introduction of a small car, up to the rail. If necessary, trim back lifting weights, trim the tower, out of the pin. The next section of the program plus you can start, repeatedly lifting plus festival, until it reaches the desired height.
Note: Install the last one before the holiday standard, to be installed on the slewing ring channel platform, the last section of a standard must be connected to the lower part of the tower, the upper legs and slewing ring connection.
