An príomhról atá ag bíseanna iarnróid in iompar ualach trom
Agus an t-éileamh domhanda atá ag dul i méid ar iompar mór-earraí amhail mianraí agus fuinneamh, tá iarnróid ualach trom ina threo tábhachtach chun tógáil iarnróid a fhorbairt . Tá riachtanais mharthanachta an-ard ag línte iarnróid trom-ualach don chóras rianta mar gheall ar mheáchan trom agus oibriú go minic na dtraenacha .}
As an important component connecting rails and sleepers, the performance of spikes directly affects the fatigue resistance of the track system. On heavy-load lines, it is recommended to use high-strength spiral spikes or special reinforced threaded spikes, which have greater anchoring force and stronger impact resistance, and can effectively resist the lateral and longitudinal load impact caused by frequent train pasáiste .
Ina theannta sin, chun feabhas a chur ar a chaitheamh agus a fhriotaíocht creimthe, is minic a dhéantar spící speisialta ualach trom as cruach chóimhiotail, agus úsáideann an chóireáil dromchla sciath chosanta ilchisealach chun a chinntiú go bhfuil siad fós iontaofa i dtimpeallachtaí crua amhail deannach ard agus báisteach aigéadach .
In daily operation and maintenance, the inspection cycle of heavy-load line spikes is also shortened accordingly, and it is usually required to conduct a comprehensive status inspection every quarter and replace them when necessary. It can be said that the quality level of spikes directly determines the operational safety and maintenance cost of heavy-load railway lines.
