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[]!

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", "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; };

Players on my Epoch server are unable to attach sling unless they are the pilot and then land chopper to attach.
They are unable to have man on ground attach while chopper hovers over.
How do I enable that option?

Hi may i add this to my mod pack with credits to you in the file

Hey there! Is there, or could you integrate, an option to bind keys for quick-releasing cargo and shortening/extending ropes? I'm part of a ~50 person unit and we regularly make use of your mod, and everyone unanimously agrees that having a way to quickly release cargo -- that doesn't involve going through a series of context menus -- would make your mod even better and applicable in more contexts. Right now we find a use for it in almost every situation, but any of those that involve active combatants tend to make it particularly risky to try at all, even if it'd be suuuper cool. Just a suggestion, but I can almost promise that the convenience would get this mod much more attention ^^

I sent a friend request to try to get in contact to help solve an issue for my vehicle. I am wanting to change the number of ropes it can deploy and lower them so it doesn't destroy the tail rotor. Recently I am having this issue where the copilot is the only one to deploy ropes.

Anyone ever found out how to enable automatic rope attaching,i dont play with many people,and it is annoying to exit the helicopter just to unsling or sling something,even if realistic

How do you make it so helicopters can sling more weight? is it a mod option or sadly a Heli-stat
