This system works with cable and chain slings, traditional hoist rings, textile slings and even with big bags.

Q - How can the system not drop loads even if the operator tries to release it?

A - The reason the hook cannot drop suspended loads is because the electric motor on the hook cannot lift more then 4 kgs due to it not having enough torque to lift more than that. Secondly the electric circuit is constantly sensing any load above 2 kg and monitors it when approaching the 4 kg threshold cut the signal. Thirdly it has the safe mode of double clicking the remote if required.

Q - What type of frequency does your remote run on and has it been approved for sale in the US?

A - The frequency is 868 for Europe, but does have the range to swap from 864 to 869. It has been approved for sale in the US but under a different frequency, 915MHz.

Q - Are there any problems with the remote control interfering with each other in separate operations?

A - There is no problem with running multiple hooks in close proximity, it runs on an encrypted message with 65,000 possibilities that follows a specific protocol. It will not cause conflict with other hooks.
