Tower crane

Tower crane is a modern form of balance crane that consist of the same basic parts. Fixed to the ground on a concrete slab, tower cranes often give the best combination of height and lifting capacity and are used in the construction of tall Buildings. The base is then attached to the mast which gives the crane its height. Further the mast is attached to the slewing unit that allows the crane to rotate. On top of the slewing unit there are three main parts which are: the long horizontal jib,

The truck-mounted telescoping boom, with its load capacity and working radius up to 24 ft, or so, is useful to handle stacks of bundled materials or small trusses transported by the truck and to be delivered to upper levels of a Building. These materials could be loaded on the truck bed with the boom. Then the boom is retracted and stowed on the truck for travel to the place where the material would be unloaded for the construction. A truck crane is designed for a more permanently

  • Guy Derrick

    • winch is left at base level as the derrick jumps; the winch operator works blind, receiving all instructions by signal or voice communication. A guy derrick must be supported at the mast base, and anchorage points are required for the guys. On a Building, a steel grillage is usually placed under the mast to transfer the loads to the host structure. The guys are then anchored to the building frame. Inasmuch as steelwork first proceeds with only partial bolting at the connections, analyses

  • Mobile Cranes

    • or worse, traditional American mobile cranes put the operator in full control. The European approach, established first with tower cranes but now applied at large, is to take that discretion away from the operator by modulating power and Building in automated limits to the crane controls. In the European Union itself, the attitude is codified in the Machinery Directive, a broad-based safety standard-applied to cranes among a wide variety of machines-that demands manufacturers eliminate

  • Tower-mounted crane

Tower cranes are the lifting machines of choice worldwide for most mid- and high-rise Building construction. They are used also on expansive sites where the broad hook sweep and the relative ease of coordinating multiple tower cranes is an advantage. There are niche markets for these as well; cable stay and suspension bridges, offshore

  • Mobile Crane Clearances

    • styles of boom heads such as the hammerhead tip or offset tip are configured to lessen the possibility of fouling. The head sheaves of telescopic booms are often similarly offset, too. The suspended load or the boom tip fouls a nearby Building or other obstruction. In tight quarters, the boom might not be capable of being raised high enough to swing past the obstruction. Urban and industrial sites can be places of heightened exposure to this peril. The boom head is obstructed

  • Mobile Crane Clearance In Tight Quarters

    • overcome this inadequacy. The tail-swing radius may encroach over an active traffic lane or face interference from an obstruction. A large crane can have a rear projecting gantry, strut, backstays, or a live mast capable of fouling trees, Buildings, or electric power lines. Placement of the crane is often close to the face of a building that prevents the tail end from swinging through a full circle. Tail-swing of a live mast or guy struts varies with the boom angle; the full working

  • Mobile Crane Ground Support Capacity
