Try using a longer cable, or you can edit some things to avoid cut the cable, look here:
[Sling.0]
hoist_extend_rate = 5 //Feet per second
hoist_retract_rate = -5 //Feet per second
position = 0, 0, 0 //Feet from datum
max_stretch = 2.0 //Max stretch distance at ultimate load
damping_ratio = 0.6 //0 for no damping to 1.0 for critically damped.
rated_load = 2000 //Characteristics tension of cable in pounds
ultimate_load = 4000 //Breaking force in pounds
tolerance_angle=70 //Angle, in degrees, used to determine lateral breaking force limit
auto_pickup_range = 10 //Max Range, in feet, for auto-pickup
auto_pickup_max_speed = 10 //Maximum speed (feet per second) for auto-pickup
hoist_payload_station = 3 //Payload station in which the hoist will load in and out of. 1 is first station.
hoist_door=1 //Door associated with hoist. Must be open for use.
