Description
Claims (3)
- リフト装置の細長で縦方向に伸長可能なマストに沿って可動で移動する少なくとも1つの積荷係合部材によって支持される積荷の重量の大きさを検知するのに適している油圧弁回路であって、
前記マストは流体動力リフトアクチュエータに動作可能に係合し、
前記流体動力リフトアクチュエータの流体圧力は、前記重量の大きさに可変的に依存するとともに前記マストの縦方向に伸長可能な異なる位置にも可変的に依存し、
前記油圧弁回路は、前記流体動力リフトアクチュエータに油圧により相互接続可能であるとともに前記流体圧力から前記重量の大きさを油圧により自動的に検知できる少なくとも1つの流体弁アセンブリを備え、当該検知された前記重量の大きさが前記マストの前記縦方向に伸長可能な異なる位置には依存しないようにした、油圧弁回路。 - 手動操作式の積荷クランプセレクタ弁に応答して積荷に対して可変の積荷重量応答把持力を自動的に与えることができる流体動力把持アクチュエータを有するとともに、さらにリフト装置の細長で縦方向に伸長可能なマストに沿って可動で移動する少なくとも1つの積荷係合部材を有する積荷把持装置を制御するのに適している油圧弁回路であって、
前記マストは流体動力リフトアクチュエータに動作可能に係合し、
前記流体動力リフトアクチュエータは、前記重量の大きさに可変的に依存するとともに前記マストの縦方向に伸長可能な異なる位置にも可変的に依存する当該リフトアクチュエータにおける流体圧力によって前記積荷を支持することができ、
前記油圧弁回路は、前記積荷把持装置に油圧により相互接続可能であるとともに前記流体動力リフトアクチュエータから前記流体動力把持アクチュエータへと流体を移送可能な少なくとも1つの流体弁アセンブリを備えることにより、前記積荷クランプセレクタ弁を同時に手動操作することなく、また前記積荷リフトセレクタ弁を同時に手動操作することなく、前記マストの前記縦方向に伸長可能な異なる位置に無関係に前記積荷に対する前記把持力を増大させるようにした、油圧弁回路。 - リフト装置の細長で縦方向に伸長可能なマストに沿って可動で移動する少なくとも1つの積荷係合部材によって支持される積荷の重量の大きさを検知するのに適している油圧弁回路であって、
前記マストは流体動力リフトアクチュエータに動作可能に係合し、
前記流体動力リフトアクチュエータの流体圧力は、前記重量の大きさに可変的に依存するとともに、前記マストの縦方向に伸長可能な異なる位置にも可変的に依存し、
