When it comes to wet disc brakes in forklifts the qualities are often debated. It has been said that the larger the forklift, the more rational it is to add the wet disc brake option. Nevertheless, this is often based on misconception. Below we have a simple outline of the pros and cons of using wet disc brakes on your forklifts. The price:
  • It is likely that there will be a price premium for wet disc brakes on your new forklift.
The performance:
  • Normally, the performance is considered better on your wet disc brakes.
  • Your regular brakes are much easier to inspect visually, indicating wear easily.
  • Both your wet and drum brakes can last for up to 20,000 hours or more.
The servicing:
  • In general, with wet disc brakes, preventative servicing must be performed more often, at intervals of 500 – 1000 hours.
  • Where an oil change does not occur regularly, the wet disc mechanism will wear out, this may result in significant mechanical and financial risks.
  • With wet disc brakes, a full service should be performed every 8,000 – 15,000 hours.
  • The application will affect the oil temperatures in your wet disc brakes.
  • If you travel at fast speeds, this can also affect oil distribution and can lead to more frequent servicing due to possible contamination from friction material or damaged seals and heat degradation.
  • The services become more expensive on your wet disc brakes due to the assembly being so complex and because there are more moving parts. Using oil coolers can help control these potential service costs.
  • Driver training can most definitely protect you against excess costs. For example, if your foot rests on the inching pedal, this can wear your discs.
You might have to pay a premium for wet disc brakes, but they will require servicing less regularly and they will last longer. However, the services will cost much more than your standard dry brakes. Contact Brakecore to discuss how you can be sure to get the most out of your wet disc brakes, and to minimise the operating costs.
Some vehicles make use of brake systems comprised partially of drum brakes. They’re called this because they use friction applied to metal drums which are attached to the wheels to slow or stop a car. While disc brakes offer better ranking performance and have also become more and more common on modern cars, drum brakes are still used in certain applications. Drum brakes are often found on the rear wheels of entry level cars to save costs, and also in classic cars. Parts that make up a drum brake system: Backing plate – It provides a solid base for the other components in the drum brake. It is attached to the axle sleeve. Brake drum – It is bolted to the wheel hub and it pins with the wheel. It is often made of cast iron, resistant to heat and wear. This is what you will see when looking at an assembled drum brake, it is the component that braking force is applied to in order to stop or slow the car down. Wheel Cylinder – The wheel cylinder contains two pistons, one at each end of the cylinder, operating the brake shoes. This cylinder applies pressure to the pistons, which then pushes the brake shoes to the drum, stopping or slowing down the car.  Each wheel needs one cylinder. Brake Shoe – This shoe pushes into the drum in order to create the friction needed to stop or slow down the car. It is secured to the backing, but still able to slide when pressure from the wheel cylinder is applied. IIt has a lining attached to it which is made up of organic or metallic compounds. The lining is what actually comes into contact with the drum and wears away with use. Each brake has two shoes. The primary shoe is closer to the front of your vehicle, and the secondary shoe is closer to the rear. It depends on the type and brand, these brake shoes might be interchangeable. Automatic adjuster – It keeps the brake shoes at a consistent distance away from the drum, even when the lining is wearing away. Return springs – The return springs pull the brake shoes back away from the drum while the driver lets off the brake pedal.

A heavy vehicle maintenance technician maintains and repairs large machines and industrial equipment, both towed and self-propelled, used in mining, forestry, agriculture, landscaping, material handling, transportation, and more. The technician needs be able to take preventative maintenance measures and regularly repair the inner combustion engines and components, as well as on-highway and off-highway vehicles, both motorised and towed; tracked and rubber-tired equipment; ground-engaging equipment; and earth-moving equipment. Maintenance and repair can involve individual components or entire systems, requiring the technician to have skill with engines, hydraulics, electronics, braking systems, and much more. The technician must utilise specific tools to diagnose functions, make alterations, repair or replace faulty components or systems, examine repairs for adequate performance, understand instructions in technical manuals, compile service reports, and certify that the work meets the manufacturers’ specifications and the requirements of legislation. The technician is frequently the link between the employer, the customer, and the manufacturer. This experience can allow the technician to advance to senior roles such as trainer, supervisor, or manager. Although technicians typically specialises in certain machines or equipment, either by choice or due to employment, the diversity of heavy equipment, along with swift changes in technology, require extensive knowledge and adaptability. Technicians should also be able to work alone or as part of a team, at a variety of hours, and in an employer’s shop, a customer’s building, or outdoors in urban or rural locations, regardless of weather. Machines often require quick intervention to enable interrupted activity to resume. Preventive maintenance is a vital part of facilities management. The aim of a successful preventive maintenance program is to institute consistent practices designed to enhance the performance and safety of the equipment on your property. Furthermore, the planned maintenance of equipment will aid in improving equipment lifespan and prevent any unplanned maintenance activity.  A successful preventive maintenance program is dependent on the cooperation of all the parties involved.  Engineering managers must rely on the knowledge, experience, and contributions of all the maintenance personnel at the property. Regrettably, the employment of a preventive maintenance program may be time consuming and costly.  This raises constant debate as to whether a preventive maintenance program is worth installing.  Will all the man hours and money spent in the program overshadow emergency repairs? From our years of experience, we believe that when the program is properly operated the benefits exceed the costs. Here are a few important benefits of a properly functioning preventive maintenance program:
  • Equipment downtime is decreased and the number of major repairs are reduced
  • Better conservation of assets and increased life expectancy of assets, thus eliminating untimely replacement of machinery and equipment
  • Reduced overtime costs and more economical use of maintenance workers due to working on a scheduled basis instead of a crash basis to repair breakdowns
  • Timely, routine repairs prevent fewer large-scale repairs
  • Improved safety and quality conditions for everyone
The work is most rewarding for those who enjoy working with their hands and are logical, curious and interested in problem solving. The technician also needs good vision, hearing, and sense of smell to diagnose problems. The occupation requires strength and stamina. Proper safety standards must be maintained at all times to avoid risk of injury involved in working on heavy equipment and with power tools.   Since Brakecore’s inception in 1983, the company has developed into one of South Africa’s premier suppliers to the agriculture, transport, industrial, marine, underground mining, and opencast mining, and earth-moving and OEM sectors as well.

In South Africa, there are many factors such as human error, environmental elements as well as vehicle and road hazards which are unsafe and ultimately lead to high fatalities. During the year of 2016, the number of deaths in South Africa related to road accidents was at an alarming 14071, this happened to be the highest total since 2007. AA had said that this is a cause of great worry and had encouraged all parties involved in South African road safety to find a way to decrease the number of deaths and increase the education of road safety in our country.   A large number of these road fatalities occur because of the lack of vehicle maintenance. Drivers fail to up keep the running of their cars and this can obviously not only put them in danger put also the lives of other road users.

Heat transfer equipment is extremely useful in a wide range of industries. The Heat exchanger design and structure of these equipment vary a lot depending on the application, where they are used as well as the heat transfer medium involved. Below are some fundamental parameters governing the efficiency of heat transfer –  
  • Nature of fluid– Property of fluid such as conductivity, viscosity and density, play a critical role in heat transfer efficiency and determination of heat transfer efficiency.
 
  • Turbulence– A high turbulence means simpler heat transfer through convection in a fluid. As heat transfer convection is a more efficient way of heat transfer than conduction, turbulence can be used to enhance the heat transfer efficiency.
 
  • Type of flow– Usually, the medium involved in heat transfer are in continuous flow. These flows can either be parallel to each other (this is known as a co-current flow), in opposite directions to each other (this is known as a counter-current flow) or approximately perpendicular to each other (this is known as a cross flow). The temperature difference between the two media varies with location along the length of the flow. Counter current flows are the most efficient because it ensures high overall temperature difference.
 
  • Temperature difference – A high temperature difference between the involved transfer equipment ensures efficient heat transfer by increasing the heat flux.
 
  • Surface area– A high surface area available for transfer of heat energy means more efficient transfer of heat energy for the same heat flux. An enhancement in the heat transfer area could be achieved by using fins on the heat transfer surface.
  There are many different factors as well, which are not related to heat transfer but still govern the design of heat exchangers. They are capital costs, operating costs, materials used to build the heat transfer machinery, as well as the fluid phase the heat exchanger is used for.

A brake is a mechanical device that stops or slows down motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion. This is accomplished by using friction. There are different types of brakes. They are as follows:
  • Electromagnetic – These brakes are often used where an electric motor is already part of the machinery. Many hybrid gasoline or electric vehicles use the electric motor as a generator to charge the car’s electric battery and also as a regenerative brake. Electromagnetic brakes slow down objects through electromagnetic induction. Electromagnetic induction creates resistance and in turn either heat or electricity. Friction brakes apply pressure on two separate objects to slow the vehicle down in a controlled manner. Related types of such a brake are eddy current brakes, and electro-mechanical brakes. These are actually magnetically driven friction brakes, but recently referred to as electromagnetic brakes as well.
  • Frictional – These brakes are commonly divided into two categories – shoe and pad brakes. It uses an explicit wear surface as well as hydrodynamic brakes, which use friction in a working fluid and do not explicitly wear out. Friction brakes are often rotating devices with a stationary pad and a rotating wear surface. There are common configurations and specifications which include shoes that contract to rub on the outside of a rotating drum, such as a band brake. The rotating drum with shoes that expand to rub the inside of a drum are commonly called a drum brake, even though other drum configurations are available as well as pads that pinch a rotating disc. These are commonly called disc brakes. A drum brake is a vehicle brake. Friction of a drum brake is caused by a set of brake shoes that press against the inner surface of a rotating drum. The drum is connected to the rotating road wheel hub. They are generally found on older cars and trucks.
  • Pumping – These brakes are often used where a pump is already part of the machinery. Some engines use a valve override, which is called a Jake brake, to greatly increase pumping losses. These pumping brakes can dump energy as heat, or can be regenerative brakes that recharge a pressure reservoir which is also known as a hydraulic accumulator.
