System benefits:

• This is the universal, basic configuration, with fixing eyebolts that allow the DRH hoist to be fixed on a frame as a double girder trolley or in a suspended execution.
• Made with modular components.
• The basic components (motor, reducer, rope drum) are assembled in a coaxial line useing 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 be inspected and has self-locking safety nuts.
• FEM service group 1Am, 2m and 3m: capacity from 800 to 20.000 kg. with hoists 2 and 4 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 4 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-50 Hz. (Voltage and frequency different 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 "L" is supplied as standard.
• Electromechanical overload device supplied as standard.

System benefits:

• Hoist with the same features as per fixed execution
• Maximum capacity is up to 20.000 Kg,  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 also available as articulated version to run on curves
• The trolley has supporting bars with circular cross-sections which support the hoist by a hinge-pin type suspension.
• The trolley is composed of an idler wheel assembly and a drive wheel assembly, both have 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 trolley motor is conical self-braking type, progressive start up and can be supplied :
  • 1 travel speed of 8 m/min or 10 m/min or16 m/min or 20 m/min
  • 2 travel speed of 16/4 m/min or 20/5 m/min
• The reducer is made with gears with helicoidally teeth which are permanently lubricated in an oil bath.

System benefits:

• Hoist with the same features as per fixed execution
• Maximum capacity is up to 20.000 Kg,  rope falls 2 and 4
• The hoist is set-down on the trolley that runs on the lower flange of the beam .
• Supporting bars with circular cross sections which support the hoist in a set-down position.
• Counterbalance on the supporting bar in order to balance the eccentric weight of the hoist. 
• The trolley is composed of an idler wheel assembly and a drive wheel assembly, both have 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 start up and can be supplied :
  • 1 travel speed of 8 m/min or 10 m/min or16 m/min or 20 m/min
  • 2 travel speed of 16/4 m/min or 20/5 m/min
• The reducer is made with gears with helicoidally teeth which are permanently lubricated in an oil bath.

System benefits:

• Hoist itself has the same features as per fixed execution
• Maximum capacity 20.000 Kg for hoists 2 or 4 rope falls with double girder trolley span 1000 mm or 1200 mm
• Maximum capacity 50.000 Kg for hoists 6 (32 t.) or 8 (40 t.) rope falls with double girder trolley span 1400 mm or  2240 mm or 2800 mm
• Electric double girder trolleys travel on top of rails fitted on the crane beams,  this allows the maximum hook path.
• The hoist can be fitted on the top of the trolley or suspended it can also be fitted in transversal position respect to the crane's 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 start up and can be supplied :
  • 1 travel speed of 8 m/min or 10 m/min or16 m/min or 20 m/min
  • 2 travel speed of 16/4 m/min or 20/5 m/min
• The reducer is made with gears with helicoidally teeth.
• Electric travel limit switches are available on request.
