A Truck Escape from the Ship

They went through the railings as a 50ft steel truss was being lowered into position during routine maintenance.
No one was hurt and pier bosses are trying to establish how the accident happened.
They are also waiting for the sea and weather conditions to improve to recover the forklifts.
Pier chief Anne Ackord said: “There was an incident today which resulted in two forklifts trucks falling through the perimeter railings.
Throughout the year we have a continuous programme of steelwork replacement and the forklifts are used in this process.
This morning the forklifts were assisting in the positioning of a new 15-metre truss which is lowered in the first instance over the side of the pier.
This is a process that has been carried out hundreds of times but we are looking into how this incident has occurred.
Crucially, no one was injured or in any danger of being injured and the recovery plan for the forklifts is already in place.
A transfer dump is a standard dump truck pulling a separate trailer with a movable cargo container, which can also be loaded with construction aggregate, gravel, sand, asphalt, klinkers, snow, wood chips, triple mix, etc.

The second aggregate container on the trailer ("B" box), is powered by an electric motor, a pneumatic motor or a hydraulic line. It rolls on small wheels, riding on rails from the trailer's frame into the empty main dump container ("A" box). This maximizes payload capacity without sacrificing the maneuverability of the standard dump truck. Transfer dump trucks are typically seen in the western United States due to the peculiar weight restrictions on highways there.

Another configuration is called a triple transfer train, consisting of a "B" and "C" box. These are common on Nevada and Utah Highways, but not in California. Depending on the axle arrangement, a triple transfer can haul up to 129,000 kilograms (284,000 pounds) with a special permit in certain American states. A triple transfer costs a contractor about $105 an hour, while a A/B configuration costs about $85 per hour.
Transfer dump trucks typically haul between 26 and 27 short tons (23.6 and 24.5 t; 23.2 and 24.1 long tons) of aggregate per load, each truck is capable of 3-5 loads per day, generally speaking.
A dumper is a vehicle designed for carrying bulk material, often on building sites. Dumpers are distinguished from dump trucks by configuration: a dumper is usually an open 4-wheeled vehicle with the load skip in front of the driver, while a dump truck has its cab in front of the load. The skip can tip to dump the load; this is where the name "dumper" comes from. They are normally diesel
