INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 driving bar commands. The sling maker is responsible for the proper location of the safety gear on the sling, as well as the adjustment checking and synchronized working of the driving bar. The pin of the roller, in its rest position, must be at the lower position of the protection plate.
INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 3 USE AND MAINTENANCE. The non-fulfilment of the following prescriptions may produce deceleration values and breaking distances which could not be in accordance with the Standard. 3.1 GUIDE RAILS: a) The used guide rails must be cold-drawn oiled for ASG-100, ASG-100 UD, ASG-65 and ASG-65 UD.
INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 The speed governor rope tension must be enough to warrant, during the governor performance, a traction of at least 300 N at the connection point of the safety gear driving bar. 3.3 RANGE OF USE: The standard P+Q table is shown bellow.
Anyway, after a real free fall performance of the safety gear, it is recommended to replace the friction parts. In that case, you can contact Dynatech requesting the manual exchange of friction parts or your nearest distributor, in order to know the procedure to be followed.
INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 4 ON-SITE ADJUSTMENT On-site adjustment is an option for the ASG series safety gear models. It is used where the distance between the safety gear and the guide rail must be adjusted during installation.

INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 Figure 2. Movement of the bolt when the safety gear operates Also check the head of the bolt can be accessed using the correct tool for adjustment. The block must always be fitted at the distance recommended by the manufacturer. The part of the block where the shoe is located must be 2 mm from the edge of the guide rail.

INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 Figure 3. Fitting method It is factory-adjusted to the corresponding type of guide rail and, therefore, this system will solve any installation defect. Where the shoe is to be moved away from the guide rail, the DIN 912 M6x8 lock bolts (3) should be loosened to allow the block to move freely.
INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 Figure 5. Bending the safety washer Make sure the flap on the washer is bent after fitting the safety gear. Make sure that one of the flat sides of the bolt head is parallel to the washer flap to ensure it prevents the bolt from turning.
INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 5.2 Calculating safety gear stopping distances The input data are the P, Q and q values for the installation. P is the sum of the mass of the empty car and the components supported (kg) Q is the lift's rated load (kg) q is the balance factor.

INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 To obtain the total stopping distance for the UCM system, the governor distance must be added to other distances due to the different delay times of the UCM system components. ASCENT As with the descent, a calculation for the natural acceleration of the system must be done.
Page 31
INSTRUCTION: ASG-Serial 1 Date: 05-12-2013 Revision: 07 DYN32.07 DECELERATION Deceleration must be calculated over the whole load range, ie from Q=0 to Q maximum, by taking a ratio λ from q to 1 in descent and from 0 to q in ascent, then checking the deceleration is valid throughout the range.

EXAMPLE An installation with a P of 600kg, a Q of 550kg and a balance factor of q = 0.4 requires a counterweight mass of 820kg.
