A tower crane accident, a ‘normal’ accident?, an investigation of the Dutch Safety Board
Tower cranes are complex and impressive installations. The increased technical quality of the cranes is the main reason why scenarios such as ‘crane instability', 'jib instability’ and ‘hoisting equipment instability’ contribute little to accidents. Nowadays ‘load instability’ is still the most dominant accident scenario in crane accidents. Tower cranes are therefore a critical component in a series of elements that make construction sites inherently dangerous.
