42、lifting device to an anchor point in accordance with the information supplied by the manufacturer. If the rescue lifting device is intended to be fitted to a tripod or similar anchor device, then test the whole unit. Withdraw the line by at least 1 000 mm from the rescue lifting device and attach te

43、st mass A to the end termination in the line. Where relevant, engage the rescue mechanism in accordance with the information supplied by the manufacturer. Hold the test mass by means of the controlling feature. Apply a force of a maximum of 250 N to the handle of the controlling feature in such a wa

44、y that it operates as intended. Check whether the force lifts the test mass. 5.5 Dynamic performance test for class B rescue lifting devices 5.5.1 Apparatus The test apparatus shall conform to EN 364:1992, 4.4, 4.5 and 4.6. 5.5.2 Procedure Attach the rescue lifting device in the intended position of

45、 the rescue lifting device to the anchor point of the test apparatus. If the rescue lifting device is intended to be fitted to a tripod or similar anchor device, then test the whole unit. Withdraw the line by ( )50 04000+mm from the rescue lifting device and attach test mass A to the end termination

46、 of the line, incorporating a force measurement instrument to measure the braking force. Raise the test mass by ( )500600+mm, with a maximum horizontal distance of 300 mm from the centre line (see Figure 1). Hold the test mass by the quick release device. In the case of rescue lifting devices with a

47、n automatic retraction function, prevent the line from retracting by a clamp. Where relevant, engage the rescue mechanism in accordance with the information supplied by the manufacturer. Release the test mass without initial velocity. Measure the braking force. Repeat the test for every intended ori

48、entation and/or position of the rescue lifting device. Where the manufacturer gives a range of orientations of use for the rescue lifting device, carry out a test at each extreme orientation and one centrally between the two, using an appropriate anchor point. A new test sample may be used for each

49、test.
