"The Donati range of jib cranes is second to none and we have no hesitation in recommending these products"
Paul Kildunne - Project Manager, DALE Lifting and Handling Specialists.
The Donati Jib crane range:
The manually rotated jib cranes in the GBA” column” series and the GBP “wall” series are designed for the handling of goods inside a plant, in a square or to serve operative positions.
The standard models are available for lifting capacities from 125 kg to 2000kg and jibs from 2m to 8m
The C-T-H versions are designed according to the three different versions of the arm.
“C” Channel version for lifting capacities from 63kg to 1000kg and jibs from 2m to 7m
The arm is made using a special section bar made of folded sheet metal, inside which the hoist-carrying trolley run.
The arm is fitted with one or two stay bolts that support the profile and connect it to the rotation tube.
This version is characterised by the extreme ease of handling due to the low inertia derived from its own reduced weight.
The arm is normally fitted with a special “channel” profile trolley, which allows it to be pushed with maximum fluidity.
“T” cantilever version, for lifting capacities from 63kg to 2000kg and jibs from 2 m to 5 m
The arm is made using a laminate T-beam form: the hoist-carrying trolley runs on the lower flange of the T-beam.
The girder is self- supporting and cantilevered, so it has no support stay bolts, and it is directly integrated with, via suitable reinforcements, the rotation tube.
This version allows the optimum use of the available space at a height due to the absence of stay bolts and allows the maximum use of the hook run. The arm allows the addition of electrical or mechanical push-trolleys.
“H” over braced version, for lifting capacities from 125kg to 2000kg and jibs from 4m to 8m
The arm is made using an H-beam section, the hoist-carrying trolley runs on the lower flange of the H-beam. The arm is fitted with one or two stay bolts to support the profile which connects it to the rotation tube.
This version allows the use of the jib crane for loads and jibs superior to those possible with the C and T versions. The arm allows the addition of electrical and mechanical push-trolleys.
electrical power supply
This is designed to power the hoist and/or electrical trolley, which runs along the jib of the crane. It uses a connection box for the connection between the line and the power festoon.
CBB: “column with articulated arm” series Maximum rotation field 360°
MBB: ”wall with articulated arm” series Maximum rotation field 360°
The manually rotated jib cranes with an articulated arm in the CBB ”column” series and the MBB ”wall” series, are designed for the handling of goods inside a plant or a building site where the presence of fixed obstacles would impede the free rotation in terms of the mobility of the arm when it is formed by one rigid element.
The cranes “with an articulated jib” are fitted with an arm made of two hinged “pantograph-shaped” segments which allow it to avoid fixed obstacles during rotation.
The standard models are available for lifting capacities from 125 kg to 500 kg and jibs from 2 m to 7 m. In the version designed for the application of manipulators, the maximum load is 125 kg.
Articulated jib
The jib cranes, both in the wall and column versions, are fitted with an “articulated arm”, which rotates on its own axis. The articulated arm is made using two cantilevered girders, which form the two hinged segments (semi-arms).
The semi-arm on the “tie” side is generally made in the boxed casing, while the “cantilever” side can be made using a T-beam or a tubular profile. cable, situated on the top of the column crane or near the bracket support in the wall version.
The column crane can be supplied, on request, with a main on/off line switch which can be padlocked. The distribution of energy takes place via a flat festoon cable which slides on a trolley along the arm.electrical power supply
This powers the hoist and for the connection between the line and the power cable has a Terminal box near the support bracket in the MBB wall version.
A main on/off line switch which can be padlocked is positioned on the column in the CBB version.The distribution of energy takes place via cable. Electrical line with the round multipolar flexible cable inserted in a channel welded under the flange of the jib. Push-button panel hanging from the hoist.
CBE: “column” series Maximum rotation field 300° (290° in the T version)
MBE: “wall” series Maximum rotation field 270° (250° in the T version)
The electrically rotated jib cranes with a motorised arm in the CBe” Column” version or the MBE “wall” version are designed for handling goods in areas that are difficult to reach, where the presence of fixed obstacles would impede the practicability of the working area.
They are used also when the frequency of maneuvers, the entity of the load and the push forces, could cause excessive wear and tear if carried out manually.
Available in standard versions for lifting capacities from 250 kg to 2000kg and jibs from 2m to 8m, in T and H models according to the different layouts of the arm.
“T” cantilever version, for loads from 500kg to 2000kg and jibs from 3m to 6m
Made using solid section T-beam: the hoist-carrying trolley runs on the lower flange of this. The girder is self-supporting and cantilevered, so without support stay bolts, and is directly integrated with, via suitable reinforcements, the rotation tube.
This version allows the optimal use of the available space at a height due to the absence of stay bolts and allows the maximum use of the hook run. The arm allows the addition of electrical or mechanical push-trolleys.
“H” over braced version, for lifting capacities from 250 kg to 2000kg and jibs from 4m to 8m
Made using an H-beam section girder, where the hoist-carrying trolley runs on the lower flange. The arm is fitted with one or two stay bolts to support the profile which connects it to the rising rotation tube.
This version allows the use of the jib crane for lifting capacities and ranges superior to those of the T version. The arm allows the addition of electrical or mechanical push-trolleys.
Rotating Arm
The arm, swiveling on its own axis on revolving bearings, is formed by a supporting girder for the run of the hoist- carrying trolley. the rotation mechanism formed by a motor reducer fixed vertically in the lower part of the support bracket, made with a reducer of epicycloidal type, with gears in a permanent oil and self- braking conical brake motor.
The drive sprocket of the motor reducer fits together with a toothed crown integral with the arm which it powers. The progressive starting up and braking is ensured by a variator of frequency (inverter) powered by alternate monophase power with 230V voltage.
Electrical power supply
To power the hoist and the trolley which run along the arm of the crane as well as the rotation motor reducer. The power supply includes two electrical control panels, one for the control of the lifting and travel unit of the hoist, while the rotation control equipment is integrated with the motor reducer.
Inside the panels, the contactors for the control of all the movements of the crane are positioned. The control circuits are low voltage (48V) obtained via a transformer protected by fuses. An easy-to-use connection terminal box, with numbered terminals, ensures simplicity and safety of the cabling of the cables related to all the external functions making any inspection easy to perform.
Power line to power the trolley-hoist formed by flexible flat multipolar cables festooned on the sliding trolleys on the lower flange of the beam.
Push-button control panel, suspended on the hoist, with a case in shockproof thermoplastic, supported by a self-supported round multipolar cable. When necessary it is fitted with a rapid socket with obliged polarity to make it easier to assemble and to replace.
On request, an independent, sliding, push-button panel can be installed along the jib of the crane, via cable-carrying sleds running inside a channel profile.
Acoustic alarm, when included, controlled by an “alarm” button serves the function of acoustic warning to indicate any dangerous situations during handling.
Electric safety limit switch on the rotation movements, installed as standard to delineate the rotation field of the arm of the crane.
Working on the auxiliary circuits at low voltage, two thresholds of intervention both in right rotation and left also carries out the emergency function in safety if there is any breakdown or malfunctioning of the first threshold of intervention.
For the connection to the line there is:
- on the jib crane a main on/off line switch which can be padlocked
- on the bracket crane a connector block. Powered by alternate electric power with three-phase voltage + neutral+earth (- 3+N+T).
Series GBR: 360° slew
The GBR series electrically rotated jib cranes are used to handle loads whose mass (high or bulky) does not allow manual handling. They are also used when fixed obstacles impede the practicability of
the working surface.
They are the ideal solution for handling:
- in outdoor squares or deposits
- on wharves, to load and unload materials for watercraft
- on wharves to haul boats
- on loading ramps, for handling materials for lorries
- for services of big operating units or assembling machines
