What Type of Gear Oil Does a Demag Crane Need

Donati DRH Rope Hoist

The DRH rope hoist from Donati combined with a trolley, which runs on i or two beams also allows horizontal movements.

The DRH rope hoist from Donati available in FOUR configuration:

Electric Wire Rope Hoist in Fixed Configuration

This is the universal, basic configuration, with fixing eyebolts that permit the DRH hoist to exist fixed on a frame as a double girder trolley or in a suspended execution.
Fabricated with modular components.
The basic components (motor, reducer, rope drum) are assembled in a coaxial line using high strength bolted connections in order to guarantee maximum use of the hook run and minimum overall dimensions of the hoist body.
Every connection can exist inspected and has self-locking safe nuts.
FEM service grouping 1Am, 2m and 3m: capacity from 800 to twenty.000 kg. with hoists 2 and four rope falls.
FEM service group FEM 1Bm, 1Am, 2m: capacity from 25.000 to 50.000 kg. with hoists 6 and 8 rope falls.
Lifting height from four m to 58 m.
Coaxial reducer with three stages of reduction and conical self-braking motor, enclosure IP55, insulation class F, complete with thermal probe as standard.
Standard supply voltage three-phase 400 V-l Hz. (Voltage and frequency unlike from the standard are available on request)
Noise level less than 85 dB (A).
Plastic protective roof above the hoist's drum type "C", "N" and "Fifty" is supplied as standard.
Electromechanical overload device supplied as standard.

Electric Wire Rope Hoist in Configuration with Normal Headroom or Articulated Monorial Trollet DST/Northward/S

Hoist with the same features as per fixed execution
Maximum capacity is up to 20 t, rope falls 2 and 4
The hoist is suspended and assembled to the trolley that runs on the lower flange of the beam
The trolley is as well available every bit articulated version to run on curves
The trolley has supporting bars with circular cross-sections which back up the hoist by a hinge-pivot type break.
The trolley is equanimous of an idler wheel assembly and a drive wheel associates, both take two wheels made of machined pressed steel and mounted on spherical bearings which are permanently lubricated.
The wheels of the drive wheel assembly are opposing and have a crown gear wheel and are connected by a manual bar.
The trolley motor is conical self-braking type, progressive start up and tin can be supplied:

The reducer is made with gears with helicoidally teeth which are permanently lubricated in an oil bath.

Electrical Wire Rope Hoist in Configuration with Depression Headroom Monorail Trolley DST/R

Hoist with the aforementioned features as per fixed execution
Maximum capacity is upwardly to 20 t, rope falls 2 and four
The hoist is gear up-down on the trolley that runs on the lower flange of the axle.
Supporting confined with circular cross sections which support the hoist in a prepare-down position.
Counterbalance on the supporting bar in club to balance the eccentric weight of the hoist.
The trolley is equanimous of an idler wheel assembly and a drive cycle assembly, both accept two wheels made of machined pressed steel and mounted on spherical bearings which are permanently lubricated.
The wheels of the drive wheel assembly are opposing and have a crown gear wheel and are connected by a transmission bar.
The steel supporting plates are adjustable along the bar and have anti derailment device.
The trolley motor is conical self-braking type, progressive outset upward and can be supplied:

The reducer is made with gears with helicoidally teeth which are permanently lubricated in an oil bath.

Electric Wire rope Hoist in Configuration with Double Girder Trolley DRT

Hoist itself has the same features equally per stock-still execution
Maximum capacity twenty t for hoists 2 or 4 rope falls with double girder trolley span 1000 mm or 1200 mm
Maximum capacity fifty t for hoists half-dozen (32 t) or eight (xl t) rope falls with double girder trolley span 1400 mm or 2240 mm or 2800 mm
Electric double girder trolleys travel on acme of rail fitted on the crane beams, this allows the maximum hook path.
The hoist tin be fitted on the top of the trolley or suspended it can likewise be fitted in transversal position respect to the crane'south beams
The trolley's frame is made in steel and the wheels are two driven and two idler.
The wheels, pressed from carbon steel, rotate on permanently lubricated bearings.
The trolley has an ant derailment device.
The trolley motor is conical self-braking type, progressive showtime up and can be supplied:
