8.1 Operation terminal protection device
Allowable deviation mm
Freight price
JB/T9018-1999
In order to ensure that the stacker can automatically cut off the power supply of the operating mechanism and stop the movement when it moves horizontally to the limit position, the following terminal protection devices must be installed.
8.1.1 Operation terminal speed limiter
When the stacker approaches the end of the lane, the device can force the high and medium speeds in that direction to be cut off. 8.1.2 Operation terminal limiter
When the stacker runs beyond the limit and collides with the vehicle block, the limiter can cut off the power supply of the operating mechanism and brake. 8.1.3 Stopper
The collision load when calculating the strength of the stopper shall comply with the provisions of GB/T3811. In addition, in order to prevent the stacker from tipping over, the stopper and the stacker shall also have buffering performance. If necessary, a buffer or other device shall be installed on the top of the terminal.
8.2 Lifting limiter
In order to prevent the over-lifting and over-dropping of goods, the stacker must be equipped with: upper limit limiter, no less than 2:
lower limit limiter, no less than 1.
8.3 Cargo position detector
In order to ensure the normal operation of entering and leaving the warehouse, the automatically controlled stacker must be equipped with a cargo position detector that can automatically determine whether there are goods at the delivery address.
8.4 Rope breaking protection device
Stackers without cab lifting should be equipped with rope breaking protection devices to prevent the cargo platform from falling due to the breaking of the lifting wire rope or chain. 8.5 Speed-limiting anti-falling device
Stackers with cab lifting must be equipped with speed-limiting anti-falling devices. When the cargo platform descends at a speed exceeding 1.15 times the rated speed due to brake failure or damage to the load-bearing parts, the descending movement of the cargo platform should be stopped and the control circuit should be cut off at the same time. 8.6 Wire rope loosening and overload protection device
To prevent the wire rope tension from being too large or too small and affecting the normal operation of the stacker, wire rope loosening and overload protection devices must be installed. 8.7 Interlock protection
Stackers must be equipped with electrical interlocks to ensure that the horizontal operating mechanism of the stacker and the lifting (or lowering) high-speed part of the lifting mechanism are powered off when the forks are extended (not reset to zero).
8.8 Safety ladder
Stackers should have safety ladders that enable operators to safely evacuate the cargo platform (driver's cab) in the event of an accident. 9 Related dimensions between building structure, shelves and stackers 9.1 At the horizontal operation terminal of the stacker (when the stacker and the vehicle stop are in a compressed state), the minimum distance between the outermost part of the stacker below 1800mm above the ground and the building must be greater than 400mm (see Figure 5). 8
JB/T9018-1999
