Cranes are large machines that are commonly used to lift and move heavy objects on construction sites. Dogs are much smaller animals that sometimes wander onto construction sites. This raises the question – can a crane hurt or injure a dog? The short answer is yes, a crane can definitely hurt or injure a dog in several ways if proper precautions are not taken.
How can a crane hurt a dog?
Here are some of the main ways a crane could potentially hurt or injure a dog:
Being struck by the crane or load
The most direct way a crane could hurt a dog is by physically striking it with part of the crane or the load being moved. Cranes have large, heavy components like the boom, cab, counterweights and the load itself. If a dog wanders into the path of a moving crane or load, it is at risk of being hit and injured or even killed. This could occur if the crane operator does not see the dog and unintentionally swings the boom or load into it.
Falling objects
Cranes lift heavy loads high up in the air. If proper precautions are not taken to secure the load, objects could potentially fall off and strike anything below – including an unsuspecting dog. Loose items dropping from the load itself, or even parts of the crane breaking off could fall and injure a dog if it is in the drop zone.
Equipment entanglement
Cranes have cables, ropes, straps and other rigging gear used to attach to loads. A curious dog could potentially wander into the equipment and become entangled or trapped. Cables under tension pose a particular entanglement hazard. If a dog became snared in crane rigging gear, it could suffer injuries in its attempts to break free or while suspended.
Electrocution
Cranes are complex, industrial machines powered by electricity. Faulty electrical equipment or exposed wires on a crane could electrify the crane and injure or kill a dog that touches it. A dog may chew on electrical cords out of curiosity, resulting in electrocution. Stray voltage from poorly grounded equipment is also a risk.
Falls from height
Some types of cranes like tower and gantry styles have long, open vertical structures. If a dog managed to climb into a tower crane cab or onto scaffolding on a structure, it could potentially fall a great distance if it lost its footing or tried to jump. Falls from height can result in devastating injuries.
Getting trapped
There are some areas on cranes and construction sites where a dog could potentially get trapped, such as in confined spaces around equipment or in holes and trenches. If a dog got stuck, it may suffer injuries like dehydration, starvation, or crushing injuries trying to escape.
What injuries can a dog receive from a crane?
Here are some examples of the types of injuries a dog could receive if struck by or caught up in operating crane equipment:
Blunt force trauma
Being struck by any part of a heavy crane or load could easily result in devastating blunt force trauma injuries. This could involve broken bones, organ damage, internal bleeding, head trauma, and abdominal injuries. Blunt force from a crane could easily be fatal for a dog.
Penetrating wounds
Sharp portions of the crane, shear points, and protruding edges on loads like exposed rebar could potentially impale or penetrate a dog if it moves into the equipment. This could cause severe lacerations, puncture wounds, and excessive blood loss.
Crushing injuries
Part of the dog’s body could become crushed if trapped beneath heavy objects like an overturned load or between swinging crane elements. This can cause serious musculoskeletal damage and compartment syndrome.
Spinal cord trauma
Forces involved in crane impacts or falls could potentially damage the delicate spinal cord. This could lead to partial or total paralysis of the dog’s hind legs or full body paralysis if the neck is affected.
Amputation or degloving
Entrapment accidents may result in parts of the dog’s body becoming severed or degloved – where skin/tissue is stripped off. This includes risks like tail amputation from getting trapped in rigging or cables. Degloving injuries are very serious.
Burns
Direct contact with hot elements of cranes or electrical burns could result in painful burn injuries, which can be more serious for animals with fur coats. Burns create a major risk of infection.
Dental trauma
Being struck in the mouth by parts of the crane could result in serious dental injuries like broken teeth, dislocated jaws, and damage to the tongue and gums.
Are some types of dogs at higher risk?
Certain types of dogs may be at increased risk of crane-related injuries compared to others:
Small breed dogs
Very small dogs like Chihuahuas are at high risk of being seriously injured if struck by heavy equipment or falling objects due to their petite size and light weight. The impacts could easily be fatal.
Puppies
Puppies are very curious and less cautious around equipment. Their small, underdeveloped bodies are vulnerable to major trauma.
Large/Giant breed dogs
While their size gives them some advantage, bigger dogs like Great Danes still risk breaking bones and organ damage if struck. Their long limbs are also prone to amputation and entanglement injuries.
Brachycephalic dogs
Short-nosed breeds like Bulldogs and Pugs are prone to respiratory issues. Dust inhalation at construction sites could trigger breathing difficulties. They also overheat easily, raising heat stroke risks around hot equipment.
Long-coated dogs
Dogs with long fur coats like Collies, Golden Retrievers, and Sheepdogs are more prone to becoming entangled in cables or rigging. Their fur poses higher burn risks around electrical hazards as well.
Senior dogs
Elderly dogs with arthritis have limited mobility to get out of the way quickly. Their fragile bones are also more prone to fracture.
How can crane accidents be prevented?
Here are some ways crane operators and contractors can help improve safety and prevent crane accidents involving dogs:
Perimeter fencing
Fenced work zones using temporary chainlink fencing helps keep dogs and other animals out of the active construction area and away from operating cranes. Gates should be closed when not in use.
Warning signs
Posting warning signs forbidding unauthorized entry, along with images of dogs crossed out, can deter dogs and dog owners from approaching cranes.
Blind spot cameras
Having cameras on cranes to cover blind spots can help operators see if any dogs get close to the crane. Reference: One study found that adding cameras reduced construction vehicle collisions by 92%.
Proximity sensors
Equipping cranes with proximity sensors that trigger audible alerts when objects like dogs get close can help. This allows operators to take quick precautions.
Traffic control
Using personnel with high-visibility vests to directing vehicle/pedestrian flow and prevent access near operating cranes is important. This is especially true in busy urban job sites.
Planning load paths
Crane operators should carefully plan load paths to avoid swinging over areas occupied by dogs. Planning proper landing areas also minimizes risks if items fall.
Communication
The crew should maintain awareness of any dogs present and radio communications to warn if dogs approach live equipment danger zones.
Breed | Key Risks |
---|---|
Chihuahua | Trauma due to small size |
Great Dane | Entanglement of long limbs |
Bulldog | Respiratory issues, overheating |
Dog injury case studies
Looking at real world examples of dogs injured by cranes helps illustrate the hazards:
Case 1: Struck by crane load
A woman was walking her small Shih Tzu dog past a construction site. The crane operator did not see them and accidentally swung a steel beam into the dog’s path. The 4 lb dog was hit by the load and thrown 10 feet, resulting in massive blunt force trauma. The dog did not survive.
Case 2: Electrocution
A stray dog climbed onto a docked harbor crane during overnight hours. It chewed through insulation on electrical cables powering the crane. The dog was electrocuted immediately when its teeth exposed energized conductors. Its body was found hanging in the machinery when workers returned in the morning.
Case 3: Entrapment amputation
A Labrador Retriever wandered into the area beneath a tower crane. It became curious about a wheel assembly and stuck its snout too far into the mechanism. When the crane rotated it crushed the dog’s snout and severed its lower jaw entirely. The mangled portion had to be completely amputated at a veterinary hospital to save the dog’s life.
Conclusion
In summary, cranes pose major risks to dogs that wander onto construction sites. The heavy equipment can easily inflict grave crush injuries, blunt force trauma, amputations, and even death. Certain types of dogs are especially vulnerable. However, following safety protocols like perimeter fencing, proximity sensors, and traffic control can help mitigate these hazards. Being proactive helps prevent tragic accidents and keeps both cranes and dogs safely separated.
