Abstract

The invention discloses a control protector for electric forklift truck attachments. The control protector comprises a gantry and a fork arranged on the gantry, proximity sensors are arranged at two ends of the gantry and the fork, a stroke switch is arranged on the fork, and the proximity sensors and the stroke switch are electrically connected with a controller. The control protector is simple in structure and convenient to use, can ensure that the electric forklift attachments difficultly collide with check blocks in a movement process, the service life is prolonged and the self stability of the attachments is enhanced.

Description

[0001] technical field [0002] The invention relates to the field of electric forklift attachments, in particular to a control and protection device for electric forklift attachments. Background technique [0003] The electric three-way stacker truck works in a straight and narrow passage. During the operation, the fork must continuously move left and right and rotate 180°. The movement of the fork is controlled by the controller to control the oil pump motor, the motor drives the gear pump to rotate, and transmits the hydraulic oil to the hydraulic motor, and the hydraulic motor drives the gear to realize the movement of the attachment. There are the following two disadvantages when the attachment is moving: ① When the fork moves to the leftmost or rightmost end, it will have a mechanical impact with the stopper, which not only consumes energy and makes a lot of noise, but also causes the cargo in the air to be unstable due to the mechanical impact. (Most electric three-w...
