SP & MP Compatible. Full replacement for in-game sling loading.

Completely optional, but if you want to give back for any of my addons, I would greatly appreciate Donations[]!

Want more? Check out my latest mods!

Also check out my Advanced Towing and Advanced Rappelling
addons for more rope features!


- Ropes can no longer attach automatically! You need to either get out of your helicopter or have someone on the ground pick up your cargo ropes and attach them to an object.
- Helicopters support up to 3 sets of cargo ropes, depending on the size of the heli.
- Once cargo ropes are deployed, any player can go to the end of the rope and pick it up.
- Once the ropes are picked up by a player, they can be attached to pretty much every object in the game.
- Players can drop ropes if they're carrying them
- Players on the ground can detached ropes from an object
- Helicopters can lift heavy vehicles


1. Subscrive via steam or dowload latest release from
2. If installing this on a server, add the addon to the -serverMod command line option

Default Sling Loading Rules:

- Helicopters can sling load all objects
- You can't sling load locked vehicles (see settings below)
- You can't sling load in an exile safe zone (see settings below)

Notes for Mission Makers:

You can customize which classes of objects can "deploy" cargo ropes by overriding the ASL_SUPPORTED_VEHICLES_OVERRIDE variable in an init.sqf file.


This will only allow objects of class Air deploy cargo ropes.

You can customize what can and can't be sling loaded by defining the ASL_SLING_RULES_OVERRIDE variable in the init.sqf file.

[ ["Air", "CAN_SLING", "Ship"],
["Air", "CANT_SLING", "Air"]

In this example, all objects of class Air can sling load Ships but not Air.

You can allow sling loading of locked vehicles by defining ASL_LOCKED_VEHICLES_ENABLED in your init.sqf file. It defaults to false.


You can allow sling loading in an Exile safe zone by defining ASL_EXILE_SAFEZONE_ENABLED in your init.sqf file. It default to false.


**Not working on your server?**

Make sure you have the mod listed in the -mod or -serverMod command line option. Only -serverMod is required for this addon. If still not working, check your server log to make sure the addon is found.


This addon is only required on the server - is it going to slow down my server?

No - while this addon is server-side only, it installs itself on all clients without them downloading the addon. Most of the time, the towing code actually runs client-side, even though you installed the addon only on the server. Magic!

Battleye kicks me when I try to do xyz. What do I do?

You need to configure Battleye rules on your server. Below are the files you need to configure:


Add the following exclusions to the end of all lines starting with 4, 5, 6, or 7 if they contain "" (meaning applies to all values):

!="ASL_Ropes" !="ASL_Ropes_Vehicle" !="ASL_Ropes_Pick_Up_Helper" !="ASL_Cargo"


If you have any lines starting with 4, 5, 6, or 7 and they contain "" (meaning applies to all values) it's not going to work. Either remove the line or explicitly define the values you want to kick. Since the values of the variables above can vary, I don't know of a good way to define an exclusion rule.

Also, it's possible there are other battleye filter files that can cause issues. If you check your battleye logs you can figure out which file is causing a problem.

The sling actions appear when looking at a vehicle, but do nothing when I select them. How do I fix that?

Most likely your server is setup with a white list for remote executions. In order to fix this, you need to modify your mission's description.ext file, adding the following CfgRemoteExec rules. If using InfiStar you should edit your cfgremoteexec.hpp instead of the description.ext file. See for more details on CfgRemoteExec.

class CfgRemoteExec
class Functions
class ASL_Pickup_Ropes { allowedTargets=0; };
class ASL_Deploy_Ropes_Index { allowedTargets=0; };
class ASL_Rope_Set_Mass { allowedTargets=0; };
class ASL_Extend_Ropes { allowedTargets=0; };
class ASL_Shorten_Ropes { allowedTargets=0; };
class ASL_Release_Cargo { allowedTargets=0; };
class ASL_Retract_Ropes { allowedTargets=0; };
class ASL_Deploy_Ropes { allowedTargets=0; };
class ASL_Attach_Ropes { allowedTargets=0; };
class ASL_Drop_Ropes { allowedTargets=0; };
class ASL_Hint { allowedTargets=1; };
class ASL_Hide_Object_Global { allowedTargets=2; };

@duda - Thank you for this and your other mods. Very nicely done! :)

I had a question about this one, how can I re-enable the 'automatic rope attaching'? I have not looked at the code and I could modify it if you 'pointed me in the right direction' if still in the code.

Personally, I would rather have a 'switch' (config/init) which enables/disables this function, for some would want it and others would not.

Let me know!

Does this work with RHS

Would you be open to compiling your 4 ropes mods into one mod?

Thanks - Just installed it. So far working like a charm :)

ok, iv been trying for a while now to get the AI to deploy the ropes once they get to a trigger and to delete them once they get to another one but i have no idea how

problem of invisible menu items was due to ACE3. The setting "Group Bar" by Ace3 UserUI Section is adjusted to be false. If you set it to true then the issue is solved by this mod. It took me so long to find out what was breaking this mod so I guess @duda it will be nice if you put this hint to your FAQ section :)

ok I see that I have a weird situation. When I chose the action "Deploy Cargo Ropes" in my dedicated server, nothing is happening because the selection of how many ropes I want to deploy is invisible... If I randomly scrol down and press again it drops the ropes.
Does anybody know why the action menu becomes invisible after the deploy rope action?

@leungkaho_p54 You technically can if you also have this mod:

Just have someone lay on the stretcher and then sling load it. Great for medevac from areas where you can't land.

Hi there. This mod, along with the other 3 advanced rope mods, is absolutely brilliant. Just one thing. I play with a mod, which adds a 250 ton heavy tank to the game. For the sake of realism, this beast should not be able to be lifted by anything but spaceship Galactica. But heavier helis lift it like any other tank.
Question: What variable do I have to change, to add a maximum weight for liftable cargos?
Found out myself. Thank you.

When a player respawns with cargo ropes deployed, they are not able to deploy new cargo ropes in there next vehicle. What variables do I need to set to nil in the onPlayerRespawn for players to be able to deploy cargo ropes after respawning?
