Definitions

  • the load carrier locking arrangement may further comprise a sensor arrangement for detecting whether a portion of a load carrier is received between the first and second gripping portions.
  • the sensor arrangement may be connected to the actuator such that the locking element may be moved into engagement with the gripping device when the sensor arrangement detects the presence of a portion of a load carrier in a predetermined position between the first and the second gripping portions of the first and second gripping claws.
  • the sensor arrangement and the actuator may be connected to the control system of the lift-truck to allow control of functions of the lift-truck in dependency of the position of the portion of the load carrier and the state of the actuator.
  • the load carrier locking arrangement according to the present disclosure will now be described more fully hereinafter.
  • the load carrier locking arrangement according to the present disclosure may however be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those persons skilled in the art. Same reference numbers refer to same elements throughout the description. The embodiments may be combined.
  • the load carrier locking arrangement 100 will now be described in detail.
  • the load carrier locking arrangement 100 comprises a base 101, typically a steel plate, and a gripping device 200 and an actuator 400 with a movable locking element 402.
  • the end portion 403 of the locking element may be brought into engagement with merely one of the first and the second grip claws 201, 202.
  • connection link discussed under figure 4 and having a protrusion 207 extending from one of the grip claws 201 and a receiving recess 208 for receiving the protrusion 207 in the other grip claw. 202.
  • the connection link synchronizes the pivotal movement of the two grip claws 201, 202 so that they are forced to pivot in unison, i.e. simultaneous.
  • the other grip claw can also not move and the gripping portions of the grip claws cannot move away from each other.
  • two actuators 400 (not shown), wherein one actuator is arranged to engage one grip claw and the other is arranged to engage to other grip claw.
  • the controller of the lift-truck may thereby be configured to activate the actuator 400 to move the locking element 402 into engagement with the gripping device 200 when the detection sensor 502 is activated and the operator push the lock/unlock button.
  • the probe 501 may be designed such that the sensor arrangement 500 detects the presence of a portion 15 of a load carrier in a predetermined position between the first and the second gripping portions 201.1, 202.1 of the first and second gripping claws 201, 202. For example such that the detection sensor 503 is activated when the portion of the load carrier is received in the gripping opening 204.
