Pit, progressive safety gear, safety gear, accompanying cables, unlocking zone, hoistway, retaining terms that need to be specifically described and
definition.
--- EN81-2..1998 7.1 paragraph 2, replaced by the following in this standard. "For the hydraulic passenger lift, this transport
Moving space should not be greater than 6mm. For hydraulic lifts, this clearance must not exceed 8 mm. Due to wear, clearance values allow
Reach 10mm. If there is a recess, the above clearance is measured from the indentation. "
--- This standard EN81-2..1998 8.2.1 add the following. "For hydraulic passenger lift and hydraulic bed elevators, in order to
Allow changes in the design of the car, the rated capacity listed in Table 1 corresponds to the maximum allowable car maximum area of the car is allowed to increase not more than the table
The area of 5% of the column value. "To consider China's hydraulic elevator car design changes in the area.

0.3.5 The requirements of this standard for electrical safety devices are. The possibility of failure of an electrical safety device in full compliance with this standard is not
Will consider.
0.3.6 When a user uses a hydraulic lift as intended, the problems caused by his own negligence and unintentional carelessness should be
To protect.
0.3.7 In some cases, the user may make some kind of reckless move. This standard does not consider the simultaneous occurrence of two reckless moves
Possibility and/or violation of the instructions for hydraulic elevators.
0.3.8 If during maintenance, a safety device that the user is not normally accessible is intentionally deactivated, the hydraulic elevator
Of the safe operation of non-guaranteed, you should follow the maintenance procedures to take additional measures to ensure the safety of personnel. Suppose maintenance personnel have been trained
Training and maintenance work in accordance with the rules.
0.3.9 Horizontal force used.

b) breakage and relaxation of all connections of the auxiliary ropes, chains and belts;
c) Rupture in hydraulic system (excluding hydraulic cylinder);
d) Minor leaks in hydraulic system (including hydraulic cylinder).
0.3.11 If the car falls from the lowest landing, the device that allows anti-fall or anti-overspeed should not operate before impacting the buffer.
0.3.12 Under the condition of mechanical failure described in 0.3.10, the descending speed of the car carrying any load (up to the rated load)
Should not exceed 8% of the nominal downstream speed.
0.3.13 Building management services equipped with hydraulic elevators should be able to respond effectively to emergency calls without undue delay (see 0.2.5).
0.3.14 Facilities that are normally to be provided for upgrading bulky equipment are described in 0.2.5.
0.3.15 In order to ensure the normal operation of equipment in the equipment room, the heat of the equipment should be considered. The ambient temperature in the equipment room should be kept at 5 ℃ ~
40 ℃ between.
0.3.16 For hydraulic elevators equipped with throttles/one-way restrictors as a precautionary measure against overspeed, account should be taken of the fact that the car-to-bumper
Or the impact speed of the ratchet device is the downstream rated speed 狏 d + 0.3m/s.
0.3.17 For a hydraulic freight elevator, when the effective area of the car with respect to the rated load is greater than the value specified in Table 1,
