Definitions

  • the present invention relates to a machine for lifting and handling loads, in particular containers.
  • the dock cranes are moved into position in order to prepare for the actual loading or unloading. These cranes are positioned on the dock in front of the ship with their jibs up.
  • the jibs are then lowered and positioned over the hold of the ship to be unloaded in order to start handling the containers both to be unloaded and loaded.
  • the cranes are each equipped with their own spreaders.
  • “twin-lift” spreader models have been utilized. These are able to handle one 40 foot container or two 20 foot ones per cycle, and unload up to 35/40 forty-foot containers or about 60/70 twenty-foot containers per hour.
  • the port is activated for all the successive sorting and distribution activities of the containers from the inbound dock to the yard or vice versa
  • the unloading of containers is done: - directly by the dock crane onto trailers (towed by a prime-mover, or tractor) for their transfer to the storage yards, where they are then placed under yard cranes in the yard for further stacking; or
  • the port is equipped with self-loading and self- unloading equipment such as fork-lift trucks, reach-stackers or straddle carriers that can transfer the unloaded containers to the yard where they are then stacked.
  • self-loading and self- unloading equipment such as fork-lift trucks, reach-stackers or straddle carriers that can transfer the unloaded containers to the yard where they are then stacked.
  • the dock cranes are able to increase their productivity. The reason for this is because by placing the container directly on the ground rather than having to place it on a trailer they can work more quickly and securely.
  • Once the containers reach the yard they are stacked one on top of the other by a series of yard cranes of the so-called RTG (rubber tired gantry) or RJVIG (rail mounted gantry) type.
  • the main object of the machine according to the invention is to handle a greater number of containers with respect to the more commonly used machines in the same amount of time and with the same comparable dimensions.
  • This and other objects have been achieved by the present machine for lifting and handling loads, in particular containers, comprising at least a first and a second vertical structures sliding on the ground, at least one scaffold frame mounted substantially horizontally on said vertical structures, and lifting means associated with said scaffold frame and suitable for lifting/lowering at least one load, characterized in that it comprises a plurality of wheels for making said vertical structures slide on the ground in a sliding direction, said wheels being mounted on wheelboxes associated with said vertical structures by interposition of at least one hydraulic cylinder connected to at least one hydraulic circuit controlled by at least a control unit suitable for regulating the hydraulic pressure in said hydraulic cylinder and evenly distributing the weight of the whole structure onto said wheels.
  • figure 1 is a perspective view of a possible form of embodiment of the machine according to the invention
  • figure 2 is a partial and front view, on an enlarged scale, of the machine's wheelboxes according to the invention
  • figure 3 is a partial and front, further simplified, view of one of the wheelboxes of figure 2
  • figure 4 is a side, schematic and partial view of the wheelbox of figure 3
  • figure 5 is a plan, schematic and partial view, of the wheelbox of figure 3.
  • a machine for lifting and handling loads, in particular containers has been globally indicated by 1.
  • the machine 1 consists of a dock crane for loading/unloading a plurality of containers 2 on/off a ship 3; this does not exclude, however, alternative forms of embodiment in which the machine 1 is of the yard crane type, e.g. a RTG or a RMG, or consists of means of transport for the containers 2 from dock to yard, and vice versa, e.g. a straddle carrier type or the like.
  • the crane 1 as shown in Figure 1 comprises a first vertical bearing structure 4a, 4b and a second vertical bearing structure 5a, 5b to support a scaffold frame 6a, 6b, substantially horizontal and connected to them. From the scaffold frame 6a, 6b two jibs 7a, 7b extend overhanging substantially horizontal on each of which lifting means 8 for lifting the containers 2 are mounted; this does not exclude, however, alternative forms of embodiment in which the crane 1 is equipped with a single jib, or three or more.
  • the first vertical structure 4a, 4b is composed of a plurality of vertical legs 4a mounted on a carrier beam 4b which connects the legs 4a and which extends in an orthogonal direction with respect to the jibs 7a, 7b.
  • the first vertical structure 4a, 4b is positioned at the median portion of the jibs 7a, 7b.
  • the second vertical structure 5a, 5b is composed of two or more vertical legs 5a mounted on a carrier beam 5b which connects the legs 5a and which extends in an orthogonal direction with respect to the jibs 7a, 7b.
  • the second vertical structure 5a, 5b is positioned at the median portion of the space defined between the first vertical structure 4a, 4b and one end of the jibs 7a, 7b.
  • the first vertical structure 4a, 4b is located near the edge of the dock 9 for loading/unloading the containers 2 on/off the ship 3 with the jibs 7a, 7b that extend to completely cover the hold of the ship 3 in order to carry out the lifting and placing of the containers 2 off and on said hold.
  • the scaffold frame 6a, 6b is mounted at the top of vertical legs 4a, 5a.
  • This consists of a perimeter structure formed by cross beams 6a, which are parallel to the carrier beams 4b, 5b, and by longitudinal beams 6b, which connect the cross beams 6a and which are parallel to the jibs 7a, 7b.
  • the cross beams 6a are associated with the jibs 7a, 7b, which are parallel to each other, of equal length and side-by-side to each other.
  • Each jib 7a, 7b is formed by a moving front section oriented towards the sea which can be raised and, when lowered, can protrude completely over the hold of the ship 3, and by a rear section oriented towards the land, which is fixed and integral with the cross beams 6a, which in turn are connected to the vertical legs
  • the length of the rear sections is almost equal to that of the front sections of the jibs 7a, 7b. This allows the containers 2 to be unloaded also from the rear part of the crane 1 as well as from the part between the vertical bearing structures 4a, 4b and 5a, 5b, in order to distribute the containers 2 rationally and efficiently with an optimization of space that permits their rapid sorting in the yard by appropriate means of transport A.
  • the lifting means 8 e.g., consist of two sliding trolleys 10 on each jib 7a, 7b and of a series of lifting units connected to the trolleys 10 which are suitable for working contemporarily to lift and/or lower a plurality of individual containers
  • each jib 7a, 7b normally has two sliding trolleys 10 that move along the jib and an engine room 11 with two lifting units (hoisting winches), one for each trolley
  • the lifting units are not described in detail in the figures.
  • Each trolley 10 supports at least two "twin-lift” type spreaders 12 and since the crane 1 is equipped with two jibs 7a, 7b with four trolleys 10, there is a total number of eight spreaders 12 that can be handled simultaneously and independently, in order to load or unload eight 40 foot containers or sixteen 20 foot container.
  • the machine 1 as shown in the figures therefore, is intended to move and handle a decisively much higher number of containers 2 with respect to the traditional cranes and consequently must be capable of supporting a substantially higher overall weight.
  • the weight of the crane 1 is transferred to the ground through a series of wheels 13, 14 associated with the carrier beams 4b, 5b in a sliding way on respective tracks (rails) 15 to move the crane 1 in an orthogonal sliding direction with respect to the jibs 7a, 7b, and parallel to the edge of the dock 9.
  • the wheels 13, 14 are made of steel and are mounted in double pairs on appropriate supports or wheelboxes 16.
  • the wheelboxes 16 are anchored along the whole length of the carrier beams 4b, 5b and are associated with them through an equalizer 17, 18.
  • Each equalizer 17, 18 is composed of two levers 17 positioned opposite to each other and associated by means of a series of connecting brackets 18.
  • the equalizers 17, 18 have a substantially median portion hinged to the wheelboxes 16 by means of a first joining pin 19, an end hinged to the carrier beams 4b, 5b by means of a second joining pin 20 and the opposite end associated with the carrier beams 4b, 5b by interposition of a hydraulic cylinder 21.
  • Each hydraulic cylinder 21 is associated with an equalizer 17, 18 and has one end hinged to the respective equalizer 17, 18 with a third joining pin 22 and the opposite end hinged to one of the carrier beams 4b, 5b by means of a fourth joining pin 23.
  • the cylinders (hydraulic jacks) 21 are connected together by a hydraulic circuit 24 which allows the transfer of the same level of oil and pressure between one cylinder and another and which is controlled by a control unit that constantly maintains the preset pressure depending on the load in any movement.
  • the wheels 13, 14 are associated with handling means 25 suitable for making the entire crane 1 mobile.
  • the handling means 25 are composed, e.g., of motorized gearboxes mounted in a number to meet the necessary power requirement for handling the crane 1 on its tracks 15.
  • a motorized gearbox 25 is provided mounted on every wheelbox 16 and arranged substantially coaxial to one of the two wheels 13, 14 associated with the wheelbox.
  • the motorized gearboxes 25 are made integral to each other in pairs in a single device 26 arranged astride of two consecutive wheelboxes 16; in this way, one motor gearbox 25 of the device 26 drives the rear wheel 13, 14 of a wheelbox 16 while the other motorized gearbox 25 drives the front wheel
  • the particular innovation of the invention is to provide a series of wheelboxes mounted on a system of hydraulic suspensions according to the invention to allow for a reduction and perfectly even distribution of the weight of the structure on both the wheels and rails, and therefore also on the dock.
  • the present invention allows to make one crane with two jibs which can be positioned perfectly centred over the two container holds of the ship to be loaded or unloaded, allowing them to work simultaneously with four trolleys and eight spreaders and up to 36 wheels per side, all contained within a maximum overall dimensions of 40 meters.
