1.8 Terms and abbreviations
The following terms and abbreviations are used in the assembly
manual.
Table 2: Terms and abbreviations
Term/abbreviation Meaning
Brake spring Cylindrical pressure spring that counteracts the hydraulic force. As a
result, only the force difference on the lifting rod is effective as the
actuating force.
CSA Canadian Standards Association
Damping spring R (DIN) Spring for gentle braking. This reduces the braking force by applying the
brake shoes continuously until the stop value is reached. When bleeding
the brake, the braking force reduces continuously from the highest value
to zero (releasing the brake shoes).
DIN devices Installation dimensions according to DIN 15430
Throttle valve D Valve to reduce the lifting and lowering speeds
EAC Eurasian Conformity mark
ED Duty cycle
ELHY® thruster Electro-hydraulic lifting thruster that converts electrical energy into
mechanical energy in a straight line movement by hydraulic means
Highest value for additional
load
Total of the forces that apply to the lifting rod head and that affect the
lifting movement and setting time, e.g. friction and mass of the connection
elements
Lifting valve H Valve to reduce the lifting speed
Lifting time Time from switching the motor on until the top piston limit position is
reached
Nominal operating point Operating point that is at 1/3 of the nominal lift
Nominal lift Maximum path that the extending lifting rod can take
Nominal reset force Minimum force at the nominal operating point for a machine with reset
spring c
Nominal actuating force Usable hydraulic force on the lifting rod head for a machine without reset
spring c
Regulation braking Braking to regulate three-phase motors to low speeds, virtually
independent of the load. A pump wheel with optimum adjustment
determines the hydraulic force with the nominal reset force. Thrusters for
regulation braking are equipped with reset spring c and damping spring d.
Regulating spring R (TGL) See damping spring
Reset spring c See brake spring
Lowering valve S Valve to reduce the lowering speed
Lowering time Time from switching the motor off until the bottom piston limit position is
reached.
