The BL4 is a 4-part lifting column specially designed for hospital and care beds; the
BL4 can of course be used for other applications where a compact lifting column with
a long stroke length is needed.
The lifting column is based on the BB3 actuator, which is practically noiseless. The
specifications comply with the demands to the lifting functions in beds as to load,
speed and stroke length.
Reed-switch:
Reed-switch gives a number of pulses for each rotation of the motor. These pulses
are used to calculate the piston rod’s position as well as to control several actuators
running in parallel.
Your nearest LINAK dealer can inform the number of pulses per stroke length.
Regarding Reed-switch connection, see Figure 6.10.
• There are mounting holes in the endplates and motor housing
• The columns must be securely mounted before operation, no rotation must be possible
• The motor housing must be mounted uppermost
• The mounting bracket tension must be adjusted correctly
Warnings
• Do only use the column within specified working limits.
• The BL4 is heavy (8.2 kg) To avoid personal injury, DO NOT DROP!
• Do not adjust anything during movement, can cause personal injury!
• The BL4 is designed for use in push applications, dynamic “Pull forces” can result in damage to the column and cause collapse of the application.
• Do not loosen any screws on the BL4, this can cause collapse of the column!
• IPX6 washable versions must not be dismantled and then rebuilt again without the motor housing being changed in order to ensure the washability.
• There must be at least 4 hours between each washing cycle to allow the BL4 to resume normal temperature.
Recommendations
• Max. storage temperatures: +50 °C.
• BL4 is for use in push applications only and only mounted with the motor housing uppermost.
• Actuators using “buffer” end-stop principle are not compatible with BL4 and CB9 systems.
• If the column is driven in end-position (end-stop switches in the actuator will be activated ) and if the hand control is kept activated you will in
some cases, depending on the column load, see that the actuator starts and stops as long as the hand control is activated.
Recommendations with washable versions:
• IPX6 Washable versions must not be dismantled and then be rebuilt again without the motor housing being changed in order to ensure the washability.
• There must be at least 4 hours between each washing cycle to allow the BL4 to resume normal temperature.
