摘要： An apparatus for a crane comprises a large-cavity pressure sensor, a small-cavity pressure sensor, a controller, a telescopic oil cylinder, and a telescopic oil cylinder regulator. The large-cavity pressure sensor can measure the oil pressure in a large cavity of the telescopic oil cylinder. The small cavity pressure sensor can measure the oil pressure in a small cavity of the telescopic oil cylinder. The controller can control an output electrical signal according to a large-cavity oil pressure fed back by the large-cavity pressure sensor and a small-cavity oil pressure fed back by the small-cavity pressure sensor, and, by means of the electrical signal, control a change of the amount of hydraulic oil flowing into and out of the large cavity and the small cavity of the telescopic oil cylinder so as to regulate the oil pressures in the large cavity and the small cavity.
