Description of the Crane

General Aspects
All of the working motions can be regulated infinitely from zero to max. speed: all operations can take place simultaneously. With a nominal load on the hook, an electric capacity governor reduces the control current to the pump adjustment of the lifting, turning and luffing gear, depending on the power input to the electric motor. These speeds are reduced and the power input to the electric motor is kept at the same level.
2.4 Pump unit
A pump unit is installed in the crane housing. It comprises an electric motor, a pump distribution gear and three hydraulic pumps. The pumps are driven by the electric motor through the distribution gear. The pump unit provides the lifting gear, turning gear and luffing gear with pressure oil. The hydraulic pumps are variable, reversible high-pressure, axial piston pumps which are connected to the hydraulic motors by high-pressure hoses.
2.5 Lifting gear
The lifting gear is mounted in the crane casing, consisting of the winch drum, the winch gear and an hydraulic motor. The winch gear is installed in the winch drum, the hydraulic motor being flanged onto the latter. The hydraulic motor is a axial piston-bent axis motor. The motors start at a maximum displacement volume and therefore at a maximum starting moment
2.6 Luffing gear
The setup of the luffing gear is the same as that of the lifting gear.
2.7 Turning gear
The turning gear consists of three turning gears which are mounted on the floor of the crane. Each turning gear engages via a gear wheel into a gear rim of the spherical turning connection, hereby transmitting the turning motion to the crane. A constant bent axis motor is fitted to each of the turning gears.
2.8 Gear oil cooler
The gear oil cooler is an oil-air cooler which cools the gear oil in the pump distribution gear (see Subcontractor documentation, Page 105). This starts at an oil temperature of 20 °C. The gear oil cooler has an oil filter which must be replaced at regular maintenance intervals (see Maintenance Intervals, Page 42).
2.9 Hydraulic oil cooler
The hydraulic oil coolers are oil-air cooler which are mounted in the return line of the hydraulic system. The spring-loaded vent flap [2.7] is automatically hydraulically opened when the pump unit is started. The oil-air cooler is switched on at an oil temperature of 40 °C. The heated air is fed-off through the opened vent flap. All functions are switched off when the oil temperature exceeds 85 °C. The pump unit and the oil-air coolers continue to run.
2.10 Heating
Electrical heating elements are installed in the hydraulic oil tank and the crane housing. The ambient temperature is controlled by a room thermostat. The oil temperature in the oil tank is controlled by a thermo sensor. The tank heating is continuously switched in at an oil temperature under 20 °C. At ca. 22 °C the tank heating is switched off.
2.11 Slake rope switch
As soon as the rope of the lifting gear within the crane column tends to slacken so that the rope threatens to jump out of the grooves, the inductive proximity switch is actuated by the rocker. This immediately switches the lifting gear off in „lowering“
mode. However, a lifting operation is possible. The correct positioning of the rope must be checked (see Chapter 6.5, Maintenance, service and discard criteria for wire rope, Page 59).
2.12 Gear limit switch
A gear limit switch is fitted to each of the winch gears. The limit switches are provided with a variable number of cams which are actuated as required by the various crane-operating conditions. (see Subcontractor documentation, Page 105).
