Among the main surprises is that technology is allowing manufactures to make units which utilize less energy overall, reduce carbon footprints, cost less to operate and provide as much power as compared to their internal combustion or IC counterparts. These new designs are creating an obvious shift within the forklift market. Lots of manufacturers have since been prompted to invest more into the development and research of these emerging machinery.
Practically 60 percent of forklift market today is with electric units, that is up from about 45 percent about 20 years ago. Increasingly more corporations and businesses are enjoying less operating costs by choosing electric. For example, the cost efficiency alone in regards to the costs of fuel and maintenance save companies thousands of dollars. The electric models provide a longer life to the fleet, compared to internal combustion units and the reduced emissions within the facility enable individuals working inside a much better air quality.
Reduced Emissions: By not emitting any carbons or carcinogens, there is a better overall improved operating condition, resulting in better health for your employees.
Less Costs: Less operating expenses have resulted from fewer moving parts and the reduction in heat being produced.
Less Fuel Expenses: When properly maintained and taken care of, batteries and chargers cost considerably less compared to Liquid Propane units and the electric units offer better costs and more stability.
Improved Operator Ergonomics: Internal Combustion or IC engines not only produce emissions but also give off much vibration and heat. Both of these situations could really result in operator exhaustion.
The term "City Crane" refers to a small 2-axle mobile crane which is made to be used specially in compact areas where standard cranes could not venture. These city cranes are great choices to be used within buildings or through gated areas.
City cranes were originally developed in the 1990s as a response to the increasing urban density within Japan. There are continually new construction projects cramming their ways into the cities in Japan, making it necessary for a crane to have the ability to navigate the nooks and crannies of Japanese roads.
Essentially, city cranes are small rough terrain cranes which are made to be road legal. These cranes are characterized by having a 2-axle design with independent steering on each axle, a single cab, a short chassis and a slanted retractable boom. The slanted retractable boom design takes up less space than a comparable horizontal boom would. Combined with the short chassis and the independent steering, the city crane is capable of turning in compact spots which will be otherwise unaccessible by other crane designs.
Conventional Truck Crane
Traditional truck cranes are mobile cranes with lattice booms. This boom is a lot lighter boom than is found with a hydraulic truck crane boom. The many sections on a lattice boom are able to be added so that the crane could reach over and up an obstacle. Traditional truck cranes do not raise and lower their loads with any hydraulic power and need separate power in order to move up and down.
Manitowoc built the first ever Speedcrane. It proved to be a successful machine although lots of adjustments had to be added later on. Manitowoc hired Roy Moore as a crane designer to help streamline the design. He understood the industry was moving towards internal combustion engines from original steam powered methods and designed his crane to change with the times. The Speedcrane was redesigned for a gasoline engine.
