The invention discloses a crane, in particular to a crawler crane with a bolt fixing type hoisting mechanism.
本发明公开了一种起重机，特别是一种具有螺栓固定式卷扬机构的履带起重机。When the sandstorm and blowing sand weather happened, the strong wind blows massive sand dust into air and causes serious air pollution.
当沙尘天气发生时，强风将大量沙粒卷扬到空中并造成严重的空气污染。During hoisting, when the goods leave the ground, firstly stop the machine and check the safety before we start the hoisting machine again.
在提升重物过程中，当重物离开地面时，制动卷扬一次，并在再提升重物之前检查安全情况。The lifting support applies the operation mode of combining the hoisting and builtin oil cylinder, being stable, safe, reliable.
起架采用卷扬与内藏式油缸联合作业的装置，平稳、安全、可靠；Hoisting the hook pulley to an appropriate degree to keep the Hoisting cable slightly tensed.
提升吊钩滑轮至足够的程度，使卷扬钢丝绳保持稍微拉紧的状况。Special winch can keeps the stability of the rig.
特殊的卷扬机构，有效保持施工的稳定性。It is prohibited that person stands within 5m to portal or bottom of decline, when winch is operating.
卷扬运行时，井口和井底5米内严禁站人。the winch reel releases the rope when a second oil inlet of the bidirectional variable pump feeds liquid;
该双向变量马达的第二进油口进液时，卷扬卷筒放绳；Frequency Change Speed Adjustment Commissioning Technology of the Main Lifter in An'gang's No. 1 Furnace
