Auto-Rappel: This harness attaches to a rope. The mechanism allows the user to drop in free-fall, slowing near the ground. The effect is very similar to a parachute drop with a very low-opening chute release, so players should use the Parachuting or Athletics skill when employing this bit of gear. The harness can be released manually with a Simple Action, released via PAN with a Free Action, or programmed to drop o by itself on landing. The harness is capable of traveling back up the rope by itself, but not with a load.

So I was looking at the grapple gun tonight, and was thinking it'd be epic if it could pull you up instead of just providing a rope to climb. Anyone modify one to do this? I'm curious if it's been done before, and how you packaged and sold it to your GM.

Just keep in mind if you let them play Batman with the Grapple Gun, sooner or later one of the players is going to play Scorpion on someone.

Not saying you shouldn't, just something to be mindful of as it's the next step if you give the GG a motor capable of lifting that level of weight.

It can make for a fairly non-lethal (besides the initial 'hit' depending on how you design the grapple- we used variable heads- so one head for normal climbing and a wider grapple head you could switch out to grab a body) way of catching someone/ dragging back someone trying to flee.

So doesn't that mean if the fleeing individual weighs more than the guy firing the grapple gun, the guy firing the grapple gun will get towed?

The Grapnel Gun is the size of a heavy pistol and uses shotgun shells to launch a length of cable 20 meters long at a selected target. Once attached, the internal battery retracts the cable at high speed, either propelling the user to the target, or bringing the target to the user. Against an unfixed opponent, treat this as an opposed Knockdown Test. If the defender's Physical Limit is lower than the Strength + net hits of the Attacker, he is pulled off his feet and dragged to the attacker at the rate of retraction. Otherwise, the attacker must succeed in a Body + Strength test or have the grapnel yanked out of his hands. Even if he succeeds, he is instead pulled off his feet and dragged towards the defender. If the rate of retraction is fast enough to incur falling damage, this applies to both the defender and the attacker as the two collide. The Grapnel Gun holds 10 charges and regains 1 charge per ten seconds when plugged in. The Grapnel can be retracted at various speeds. Switching between these speeds requires a Change Device Mode Simple Action.

Steady: The Grapnel is retracted at a speed of 3 meters per combat turn, fast enough to clear a 1 story building quickly but safely. The Grapnel needs at least 1 charge to retract at this speed, but can be used indefinitely. This requires a minimum Strength of 2 to hold onto the gun. If the user lacks sufficient strength, they must make a Strength + Body test, with a threshold equal to the difference between their Strength Attribute and the requirement for the rate of retraction, or else have the gun pulled out of their hand.
Slow: The Grapnel is retracted at a speed of 5 meters per combat turn. This expends 1 charge, and requires a minimum Strength of 3 to hold onto the gun.
Fast: The Grapnel is retracted at a speed of 10 meters per combat turn. This expends 2 charges, and moves the target at high enough speed that they must resist falling damage as if they fell 5 meters. This requires a minimum Strength of 4 to hold onto the gun.
Turbo: The Grapnel instantly retracts the full length of its cable, moving at a speed of 20 meters per combat turn. This uses up 5 charges, and causes 10 meters worth of falling damage on impact due to the high speed of retraction. A minimum Strength of 6 is required to hold onto the gun..

Wireless: Laser range finders, ultrasound and weight sensors between the gun and the head of the cable are able to quickly calculate the exact distance being traversed and the full load being pulled, allowing the Grapnel to calibrate its retraction speed to slow to a safe stop. No falling damage is taken, no matter how fast the grapnel is retracted. In addition, changing retraction speeds requires only a Free Action, and it recharges through induction at a rate of 1 charge per hour.

Optional Heads:

Electromagnetic Head: This Grapnel head is designed to latch onto any ferrous metal, such as the bodies of vehicles or heavy girders. When activated, any metal target, or target that contains metal, receives a -4 penalty to its defense roll to avoid the Grapnel. When properly attached, the rope will break before the magnet fails. Turning the Magnet on or off requires a Change Device Mode Simple Action.
Wireless: The magnet can be activated and deactivated as a Free Action.

Gecko Head: This Grapnel Head has a large sphere of amorphous Gecko pad material the size of a softball. On impact, it flattens against the target, dramatically increasing its surface area and holding fast. The Gecko Head can stick to almost any surface and support the weight of a full grown Troll without slipping, but it becomes worthless when wet and can't stick to surfaces coated against adhesives. Once stuck, removing the Gecko Head requires a Complex Action to carefully peel it off its target, or a Simple Action if liquid can be poured over it.
Wireless: The adhesive in the Gecko Pad can be temporarily disabled with a Wireless Signal, allowing it to be removed as a Free Action.
Damage Modifier: -2S
AP Modifier: +1

Spike Head: This Grapnel Head is a hardened, diamond tipped spike, designed to pierce through a target before deploying barbs to hold it fast. The Spike can pierce any barrier up to Structure Rating 12 and deals 1 box of damage to the barrier. Against living targets, it becomes lodged in their armor if the damage is converted to stun, or gets embedded in their body if it deals Physical. Removing the spike once its lodged into a target requires a Complex Action and a Strength + Body (4) test. Pulling the spike out like this deals two boxes of damage to Structures, or base weapon damage to a living target that took Physical damage from the initial attack. Alternatively, it can be removed without additional damage using a First Aid + Logic (2) [Mental] test.
Wireless: The internal barbs can be retracted with a wireless signal, allowing the spike to easily slip out of whatever hole it made. If lodged into a living target, this still requires a Complex Action.

Since an Implanted Grapnel Gun cannot be yanked out of your hand, it instead deals 1 box of unresisted physical damage for every point of strength you're missing as the implant yanks on the meat its attached to, Which can be prevented by the Body + Strength test as usual.

How far can it pull you in a turn? Does it automatically reel you in during the firing action, or is it a separate action for that?

doesn't say sadly.
"this gun can shoot a grapling hook more than 50 meters(me:because the lines are actually 100m long, i'd change that accordingly). It comes equipped with an internal spool.If used as a weapon, it fires at heavy crossbow ranges and does 5m stun damage. The grapple line can easily hold 1000kg."
so, going by the thought that it can winch 1000kg(a ton), i'd say lower weights get dragged pretty damn fast.
if you go with only 50m, then you need to do some maths to get to a point where about 30 seconds(10 combat rounds) are used to move 1t of weight i'd guess.
That is probably straight up as well, so sideways would be different. And then go from there.

We CAN always just escalate things and have the Troll carry the vehicle weapon Harpoon Gun around . .

Shadowrun Technology is advanced enough for it.
And the weakest part in the equation will always be the person holding it anyway.

The catalyst stick is only for the stealth line, not for the normal one though.
