Abstract

Bir serbest kaldırma direğine sahip bir yük kaldırma sistemine ait yük sıkıştırma elemanlarının ağırlığa duyarlı otomatik kontrolünü gerçekleştirecek biçimde uyarlanmış hidrolik valf devresi. Yük kaldırma sistemi genel olarak bir yüke bir kavrama kuvvetinin uygulanmasına yönelik bir veya daha fazla akışkan güçlü hareket vericiyi, bir serbest kaldırma hareket aralığına ve en az bir ana kaldırma hareket aralığına sahip en az bir uzun, boylamasına uzayabilen akışkan güçlü kaldırma cihazını ve manüel olarak çalıştırılan yük sıkıştırma ve yük kaldırma seçici valflarını içermektedir. Hidrolik valf devresi bağımsız bir biçimde, bir yük kaldırılırken yük sıkıştırma elemanları üzerinde ağırlığa duyarlı kontrol olanağını, yük sıkıştırma veya yük kaldırma seçici valflarının eş zamanlı manüel olarak etkinleştirilmesi söz konusu olmaksızın yük sıkıştırma elemanları üzerinde tam zamanlı otomatik ağırlığa duyarlı kuvvet kontrolü olanağını ve algılanmış yük ağırlığının, söz konusu algılanmış yük ağırlığı kaldırma cihazının boylamasına uzayabilen konumundan büyük ölçüde bağımsız olacak biçimde dengelenmesini sağlamaktadır.Hydraulic valve circuit adapted to realize weight sensitive automatic control of the load compression elements of a lifting system with a free lift mast. The load lifting system generally includes one or more fluid power actuators for applying a gripping force to a load, at least one long, longitudinally extensible fluid powered lifting device with a free lift range of motion and at least one main lift range of motion, and manually operated Includes load compression and lift load selector valves. The hydraulic valve circuit independently includes the possibility of weight sensitive control on the load squeezing members while a load is being lifted, the possibility of full-time automatic weight-sensing force control on the load squeezing members without simultaneous manual activation of the load squeeze or load-lifting selector valves and the perceived load weight. The perceived load weight ensures that the lifting device is balanced substantially independent of its longitudinally extensible position.
