Rectifying faults in lifts
Overview
This standard identifies the competences you need to rectify faults on traction and hydraulic lifts, in accordance with approved procedures. This will involve rectifying faults in cases of breakdowns, and will include faults in landing doors, lift doors, safety equipment, machine equipment, controller equipment, hydraulic equipment and ancillary equipment. Components to be replaced will include motors, pumps, switches, sensors, control boards, valves, brakes and `lifed' items, such as bulbs, grease and lubricants. You will also be expected to check the repaired lift and to confirm its correct function. You will be required to select the appropriate tools and equipment to use, based upon the operations to be performed, the equipment, and the faults to be rectified.
Your responsibilities will require you to comply with organisational policy and procedures for the fault rectification activities undertaken, and to report any problems with the repair activities, tools or equipment used that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You must ensure that all tools, equipment, and materials used in the fault rectifying activities are removed from the work area on completion of the activities, and that all necessary job/task documentation is completed accurately and legibly. You will be expected to work with minimal supervision, taking personal responsibility for your own actions, and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying repair and rectification procedures on lift equipment. You will understand the operation of the lift equipment, and its application, and will know about the repair and rectification procedures, in adequate depth to provide a sound basis for carrying out the activities, correcting faults and ensuring that the repaired lift operates safely and correctly, to the required specification, and remains compliant with all standards and regulations.
You will understand the safety precautions required when carrying out the repair activities, especially those for isolating the equipment. You will be required to demonstrate safe working practices throughout, and will understand your responsibility for taking the necessary safeguards to protect yourself and others in the workplace.
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety legislation and other relevant regulations, directives and guidelines
- follow the relevant maintenance schedules to carry out the required work
- carry out the maintenance activities within the limits of your personal authority
- rectify faults in the specified sequence and in an agreed timescale
- report any instances where the maintenance activities cannot be fully met or where there are identified defects outside the planned schedule
- complete and store all relevant maintenance documentation in accordance with organisational requirements
- dispose of waste materials in accordance with safe working practices and approved procedures and leave the work area in a safe condition
Knowledge and Understanding
You need to know and understand:
- the health and safety requirements of the area in which you are carrying out the fault rectification activities
- the specific safety precautions to be taken when carrying out the fault rectification on lift equipment
- the safe working practices for lifts (as described in BS7255)
- the isolation and lock-off procedures or permit-to-work procedure that applies
- the importance of wearing protective clothing and other appropriate safety equipment (PPE) during the fault rectification process; the type of equipment to be used, and where to obtain it
- hazards associated with carrying out fault rectification work on lifts (such as handling oils/greases, stored pressure/force, electrical contact, process controller interface, using faulty or damaged tools and equipment, using practices/procedures that do not follow laid-down procedures), and how to minimise them and reduce any risks
- what constitutes a hazardous voltage and how to recognise victims of electric shock
- how to reduce the risks of a phase to earth shock (such as insulated tools, rubber matting and isolating transformers)
- the correct procedures for the emergency release of passengers
- where to obtain, and how to interpret, drawings, circuit diagrams, specifications, manufacturers' manuals and other documents needed in the fault rectification process
- the principles of operation of the equipment being repaired
- the procedures for replacing or adjusting faulty equipment
- how to evaluate the various types of information available for fault diagnosis (such as user reports, monitoring equipment, sensory inputs, machinery history records, and operation of the lift)
- how to evaluate sensory information (sight, sound, smell, touch)
- the types of tools and equipment that can be used in fault rectification (such as mechanical measuring instruments, electrical measuring instruments)
- how to check that tools and equipment (such as mechanical measuring instruments, electrical measuring instruments) are calibrated or configured correctly for the intended use, and that they are free from damage and defects
- the correct and safe procedure to be adopted for the disposal of waste of all types of material
- how to relate previous reports/records of similar fault conditions
how to prepare a report which complies with the organisational policy on fault rectification
the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
Scope/range
Carry out all of the following during the fault rectifying activity:
- verify that the fault exists

- ensure the safe isolation of equipment (such as mechanical, electricity, fluids)
- provide and maintain safe access and working arrangements for the area
- follow the approved maintenance schedule for rectifying faults in lifts
- carry out the activities using appropriate techniques and procedures
- return the lift to service on completion of the repair activities
- ensure that any potential defects are identified and reported for future action
- dispose of waste materials in accordance with safe working practices and approved procedures and leave the work area in a safe condition
