Faced with the impossibility of operating the devices at temperatures lower than 35 ºC, the need is established to provide high temperature warnings in the operation and maintenance instructions, and on the devices themselves, accompanied by a legend (the client will mark it if they deem it appropriate).
  • Page 9 NDT-NFT-NAT ELECTROHYDRAULIC BRAKES Instructions for assembly, adjustment and maintenance  To avoid the falling of materials during manipulation, adequate information will be provided to staff on the correct manipulation of loads. Tools with a comfortable grip must be used and they must be kept clean and in good condition. CE marked safety footwear will also be used to minimise injuries in the event of materials falling on lower extremities.

  • Page 14: Brake Operation

    NDT-NFT-NAT ELECTROHYDRAULIC BRAKES Instructions for assembly, adjustment and maintenance 2. BRAKE OPERATION. The electrohydraulic drum brakes brake using the force exercised by a spring. The mounted compressed spring tends to extend itself, this extension force (Fx) is conveyed to the arms creating a force (Fa) that is equal but in the opposite direction in each arm. Due to the relationship of the distances (A and B) that there is in arm with respect to the rotation axis (O) a force (Fp) is created that is equal in both brake shoes in the opposite direction that makes the brake operate.
  • Page 15 NDT-NFT-NAT ELECTROHYDRAULIC BRAKES Instructions for assembly, adjustment and maintenance The electrohydraulic drum brakes release the brake or open when the thrustor brake lifter is electrically connected. The thrustor brake lifter assembly, adjustment and maintenance instruction is 01.165I. When the thrustor is connected it generates a force (F) capable of overcoming the force Fx1, the force generated by the spring when the brake is open, bear in mind that Fx1>Fx where Fx is the force of the spring when the brake is closed.

    3. BRAKE ASSEMBLY. To assemble an electrohydraulic brake onto the related drum, proceed as follows: 3.1. The first thing an operator must do when he is going to assemble an Antec brake is unpack it. When the brakes leave the factory, they are always packaged to ensure maximum safety during transportation.
  • Page 17 Therefore, possible drum and brake bracket machining defects have in no event been taken into account. ANTEC thinks it is worth mentioning that possible flaws NOTE regarding parallelism and flatness in the brake's disc and securing bracket could reduce the contact surface area between the lining and disc.

  • Page 30 NDT-NFT-NAT ELECTROHYDRAULIC BRAKES Instructions for assembly, adjustment and maintenance 5.5. All articulations of Antec brakes are mounted on self-lubricating bearings. In the event that a client were to order a brake without these self-lubricating bearings, we recommend that the brake’s articulations should be lightly greased, avoiding oil spilling onto the linings or the pulley.

Loosen thenut to open the brake.
  • Page 32 NDT-NFT-NAT ELECTROHYDRAULIC BRAKES Instructions for assembly, adjustment and maintenance 6.4.- For both brake shoes the disassembly process is the same for which the axle of the brake shoe must be dismantled with all its components and after this the shoe must be rotated around the drum, up until the position shown in the following diagram, so that it can be removed.
  • Page 33 NDT-NFT-NAT ELECTROHYDRAULIC BRAKES Instructions for assembly, adjustment and maintenance 7. BRAKE OPTIONS. 7.1. AUTOMATIC RECOVERY (RA). For any explanation on automatic recovery, we shall base this on the following diagram with its related markings. T.D.S.: BC.TDS.00015I Rev.01: January 2012. www.antecsa.com Page.
  • Page 34 NDT-NFT-NAT ELECTROHYDRAULIC BRAKES Instructions for assembly, adjustment and maintenance 7.1.1. AUTOMATIC RECOVERY OPERATION DESCRIPTION. The electrohydraulic brake system without automatic recovery is based on the fact that a short part of the TURBEL brake lifting path is allocated to the reserve for lining wear, the remaining part of the path being used for opening the brake shoes.
  • Page 35 Remember to fit the pin (12) into its place after mounting the arm in its position. 7.1.3.- ADJUSTMENT AND SETTING OF A BRAKE WITH AUTOMATIC RECOVERY All brakes leave Antec adjusted so that the client does not need to adjust them, but we do deem advisable that the latter should know NOTE how to perform possible future adjustments and settings.

  • Page 41 Instructions for assembly, adjustment and maintenance 7.3. BRAKE SHOE LINING WEAR DETECTOR (DD). Antec brakes have an option for mounting the shoe lining wear detector by inserting two cables into the lining as shown in the following diagram. The cables are connected to a connection terminal that is prepared so that the client can make the required connections to his electrical power equipment.
  • Page 42 Instructions for assembly, adjustment and maintenance 7.4. BRAKE MANUAL UNLOCK (DM). The manual unlocking function in Antec brakes is intended to replace the activation of the opening of the brake by means of the TURBEL brake lifter, by manually activating the opening of the brake by means of a lever.
  • Page 43 Instructions for assembly, adjustment and maintenance 7.5. DESCENT VALVE IN TURBEL BRAKE LIFTER (VD). Antec brakes activated by the TURBEL brake lifter may be fitted with the option of a descent valve (VD) for TURBEL brake lifters. The function of mounting a TURBEL brake lifter fitted with a descent valve (VD) is to control the closing time of these brakes by means of this valve, an option that may benefit the operation of these brakes under certain working conditions.
  • Page 44 NDT-NFT-NAT ELECTROHYDRAULIC BRAKES Instructions for assembly, adjustment and maintenance The oil flow is fully open and the movement of the shank is at the maximum (it moves as if there was no valve) when the marking on the descent valve is as indicated in the following diagram.

When for whatever reason it is desired that a brake should provide a braking torque that is lower than that set as the minimum in accordance with the application tables shown in point 1.4 of the instructions, it will be necessary to fit the brake with a “reduced torque"...
  • Page 46 NOTE department. For any clarification regarding brake spare parts, please contact the ANTEC After Sales Service, specifying the brake model and serial number. - On performing the previous operation the nuts (1) will have been separated from the bushing (2) by measure "B". This distance is the reserve for brake lining wear. Take care of this distance and before the bushing (2) touches the nuts (1) the brake will have to be adjusted once again.
