We began approaching hanger both wing walkers (Name and Name1) were in place; Crew Chief (Name3) was guiding us into the gate. As we got closer to our stoppage point; I saw Name and Name1 jump. At that point the driver (Name4) pressed on the brakes. Because of the weight of the aircraft it takes time for the Goldhofer [tug] to stop. This caused the accident in colliding with the forklift. I was in the passenger's seat. As I looked back I saw when the impact occur. The driver pressed on the brakes but it takes time to stop.The accident happen because of the wands failing and the brakes on the Goldhofer.The Crew Chief notified the Operations Manager and maintenance approach the aircraft right away to inspect the engine. They were waiting to work on the aircraft. [Suggest] getting better equipment.
Pulling the plane to the parking spot. I was the guide man. A piece of equipment was over the line that was touched.  Maintenance placed there.  Signaled the driver to slow down; then stopped him before the equipment. I guess the weight of the plane forced the tug to keep going for a little bit. The cowling touched the lift. I was the guide man; Name4 was the driver; Name1 was the left wing walker and Name was the right wing walker. My left wing walker did use the TTWS (Tow Team Warning System) but it did not work as it was supposed to; since half of them don't work and brought the plane in so that not to block another hangar; outside spots XX and X1 and as you see in the pictures the safety lines are faded and should be 10 feet from the edge of a plane but on XX it's not and Maintenance thinks that it's a storage area to put equipment.Maintenance parked their equipment over the line that we can't move we tried to park out of the way as close as we can so that to be out of the way of other planes. When this happened the manager was notified also production control. And Maintenance came over to move their equipment. [Suggest] Not to park inside the safety envelope.
Technicians reported a collision with a fork lift while towing the aircraft to the hangar. They also reported the TTWS (Tow Team Warning System) did not alert the crew as expected.
