PREVENTIVE MAINTENANCE, COLLAPSED BEARING AT 12M HIGH
August 23, 2017
Door maintenance, collapsed bearing at 12m high.
Routine door maintenance prolongs the operational life of the installation and ensures that the installation is kept in good working order.
It ensures that the door is working in a safe and efficient condition – helping to prevent accidents and damage which in turn results in down time, effecting work flow, productivity and resulting in loss of revenue.
Under current regulations, it is an Employers duty to protect it’s employees from injury by ensuring that all equipment (doors and shutters) are fit for purpose in good repair and subject to a monitored maintenance Program. Failure to keep doors properly maintained could invalidate warranties and could result in prosecution under the Health and Safety at Work Act 1974 Regulation 18 (2) (B).
Reducing the risk of serious injury means setting boundaries for anyone operating your industrial overhead door and ensuring all areas are properly marked.
Tridoor has been producing high speed doors for industrial businesses for 20+ years. Our high speed doors provide both ease of access and high security.
In simple terms yes. Roller shutter doors are manufactured using individual components that make up the full door system. The main components of a roller shutter door is the barrel assembly and the door curtain, these too are made up of individual items and can be replaced but the extent of this damage or wear to these two vital parts can sometimes make replacement a more cost effective option. The roller shutter door barrel: The barrel assembly or axle is often a steel tube, the size and thickness is determined to prevent deflection of the tube under the weight of the door curtain (industry standard is 1:400). The barrel may contain shafts, bushes, springs, motor and brakes. Depending upon the age of the door, all the items are readily available and replaceable. The roller barrel assembly is a classed as a suspension element and carries the weight of the roller shutter curtain, It is recommended that any repairs to the barrel assembly is carried out by a specialist door contractor who has the expertise to identify the parts, faults and can carry out the repairs safely. Replacement of motors and safety brakes should only be carried out by a specialist door contractor
Roller shutter maintenance depends. Legal rights say industrial doors need maintenance every year but a domestic door can last longer due to lack of use.
In the design, manufacture and maintenance of industrial doors, demands of site, users and the environment are all taken into consideration. A suitable and sufficient risk assessment should be carried out for compliance and even where state-of-the-art requirements have been achieved, residual hazards are still present. Where recital 14 of the machinery directive is concerned, state-of-the-art is not cutting edge safety but the minimum level of safety required. Automatic doors can be opened by various means ranging from a simple push button, remote control, radar or induction floor loops, which activate the door and the door will raise to its upper most position. Once the door has reached its fully open position, for a fully automatic door, usually a timer is activated and the door will count down for a pre-determined time and the door will commence to close. An automatic door can also be where the door will remain at its fully open position indefinitely and requires a signal to close. Upon receipt of this signal, the door will begin to close automatically. For a door to work automatically in the closed position, safety features need to be present to prevent the door closing onto an obstruction or person. This can be in the form of a safety edge in conjunction with a low-level safety beam where either breaking the beam or contact of the safety edge will stop and return the door to the open position. Where a light barrier is installed, this is a full light curtain grid across the door opening and in the path of the closing door to a height of approximately 2500mm; crossing this beam at any point will stop and return the closing the door. As mentioned previously, recital 14 of the Machinery Directive relates to the minimum requirements for safety therefore residual hazards can still be present. When an automatic closing door is installed or maintained, the specialist door contractor should carry out a force test of the closing door. The force of the closing door should not exceed 400n, should reduce back to 150n in 0.75s to allow the door to stop and return so no overrun is present and should reduce further to 25n within 5s. The test is carried out at specific locations beneath the door and at heights where the door reaches full speed. A special force test meter is required to measure these forces on both doors and gates and should be calibrated on an annual basis. The test is recorded and a certificate is issued in order for the door to be compliant.
Industrial doors have lots of benefits to your business beyond keeping the breeze out! Installing a door properly and keeping it maintained can be a big boost for your company's image.

Shutter Safety brakes, anti fall back devices for vertically acting door fall back protection STANDARDS: Construction Products Regulation (CPR) (EU) 305/2011 EN 13241: 2003+A2:2016, Industrial, commercial and garage doors and gates, Product Standard, Performance Characteristics. EN12604: Supporting structures, fixings, suspension elements and door leaves should be designed to withstand 2 x the total foreseeable load without permanent deformity. Supporting structures, fixings, suspension elements, fixings, door leaves and travel stops should be designed to withstand 3.5 x their total foreseeable load without ultimate structural failure Rolling shutter curtain attachments should be secured against normal loads, shock loads i.e. safety brake engagements. EN 12604 suggests at least 50% of barrel is covered at fully closed position. Vertically acting door static balance Vertically moving door leaves should achieve static balance such that: they remain static in the fully open and fully closed position Any slight out of balance movement when the door is stopped in any other position should not exert a static weight of more than 15kg Vertically acting door fall-back protection Vertically moving doors should be protected against failure of vulnerable balancing system components. Some structures within the suspension system can be considered to be resistant to failure provided they achieve the design strength of EN 12604 Other more vulnerable elements such as springs, cables, drive chains, gears, functional brakes (used to stop doors in normal use), should be provided with a back up system. The protection should be effective that in the event of failure of any one single vulnerable balancing component The door leaf must not exert a static weight of more than 20kg The door leaf must not travl more than 300mm within 2500mm of the ground or any other permanently available access level.

Give and Gain Day 2019 saw Tridoor at Lixwm Primary School, Holywell. This years task was to help convert an un-loved out building into an outside classroom, decking and stage. We had the pleasure of installing a pair of patio doors, an electric awning and a decking stage area with handrails.
Barnsley Council has approved plans which will see £1 million spent on improving the look of district town centres.
