Is the construction company liable for the injuries though the child was clearly on the property without permission?

The Jameson family have three young children, ages 8, 6 & 2. They live in a home in an urban area adjacent to a local construction company. The construction company owns multiple construction vehicles, including several back hoes. The property is gated and fenced and there are “NO TRESPASSING” signs posted throughout the property. One day, the Jameson’s 8 year old daughter managed to climb through a hole in the company’s fence to play on the property. While there, she climbed up onto a back hoe and cut herself severely on a loose bolt. As a result of the cut, the Jameson’s daughter required 28 stitches and will need surgery to repair tendon damage. Is the construction company liable for the injuries though the child was clearly on the property without permission. Explain your answer thoroughly.
