In what order should I evaluate the criteria when choosing a crane remote control?
Evaluate the following seven headings in order: channel requirement, the receiver's mounting location and protection requirement, the actual working distance, receiver supply voltage, load type and contactor requirement, remote control power preference (Li-Po rechargeable or 3xAAA batteries), ambient conditions and the maintenance plan. This order eliminates the risk of having to change the receiver later.
Make the selection in the following order; each step narrows down the next.
- Channels: every bidirectional movement uses two channels. Decide between the 2, 4 and 6 channel options bearing in mind the movements to be added later as well.
- Receiver mounting: if there is a protected panel, the panel-mount type; if the receiver will stay outdoors, an IP67 outdoor enclosure.
- Distance: measure the actual diagonal distance. Open-area values are approximately 100 m on the SF series and approximately 150 m on the ST series; leave a margin on top.
- Supply: the LF100R receiver can be supplied with 12/24V DC or 220V AC; for the SF200's LT200R receiver, 12/24V DC is stated. Check which voltage is available in your panel.
- Load: will the relay contact drive the motor directly, or a contactor coil? Plan for derating and a snubber with an inductive load.
- Remote control power: the Li-Po rechargeable LT200 or the 3xAAA battery LF200; will you be able to establish charging discipline in the field?
- Environment and maintenance: dust, water, temperature, seal and gland checks, the need for a spare remote control.
