How to ensure the safety of the leveling machine during construction?

Why use armoured joints at all? Construction joints are an essential part of creating a concrete floor. But left unprotected, they will quickly become damaged once the building is brought into use –leaving the building owner or operator with repair costs and expensive down-time. A damaged construction joint is more than just unsightly. Materials handling vehicles can suffer costly damage too on an uneven surface; and it can even present a health and safety issue for forklift drivers. The best solution is to armour joint arrises during construction, to build in protection from the start. It is easy and cost-effective, and reaps benefits for the lifetime of the building. Guidance on choosing the right joint Here are some of the factors to consider when choosing an armoured joint. Our helpful joint selector can also guide you in choosing the best product to armour joint arrises on your project. Building use. Consider whether the building will have one use in its lifetime, or if this may change. You can future-proof the floor by choosing a versatile joint, such as Permaban Signature or Wave. These allow vehicles to cross the floor freely in any direction, now and in future. Traffic. Consider the type of vehicle wheel being used, plus traffic frequency and speed ('duty'). Vehicle direction determines how much impact a joint endures. Straight joints such as AlphaJoint are Eclipse are fine where vehicles won't cross directly. Otherwise, choose Signature or Wave to prevent impact (see below). Service. If cleaning chemicals are regularly used, a stainless steel joint (AlphaJoint CSS) will withstand these and look good for longer. If a joint is likely to be regularly exposed to wet conditions, choose our galvanised Signature, Eclipse or Wave. Hazards. If the building handles substances which must not leach into the ground, or where the joint gap itself would pose a hazard to pedestrians, then cover the gap permanently with SignatureSlide, or fill with a joint sealant. Floor construction. 'Jointless' floors include armoured joints, but not saw-cut joints, so the gap sizes can be slightly larger. Take the likely gap size into account, and how it might be filled. SignatureSlide handles larger gaps and ensures no joint gapis exposed. What is impact? If a vehicle crosses a straight joint at 90° there is a risk of impact damage. This is because the wheels drop momentarily in the gap between the two straight sides of the joint. Repeated impact on a saw-cut joint, or even a straight armoured joint,causes damage to the surrounding concrete, leading to maintenance costs and downtime. A shaped joint arris (Signature or Wave) has no straight lines–hence the wheels cannot fall between the two sides, so no impact can occur. Shaped joints therefore make the ideal choice for directional traffic situations, or where a building owner wants to ensure flexibility for how a building may be used in the future. The value-engineered approach Traditional-style armoured joints only account for about 5% of the material cost of the floor slab. Joints are a small part of the overall cost –but can make an enormous difference to the floor's lifetime performance. By using a combination of Permaban armoured joints you can create an optimum specification without a significant cost increase. For example, using Signature and Eclipse together in a specification will provide superior joint protection, but with a less than 1% increase in material cost. Using Signature alone means only a 3% increase in material cost. But remember that any additional up-front costs will be more than recouped over the life of the building, due to reduced floor and vehicle maintenance costs. The building's versatility, and saleability, can also be improved. Download our quick comparison guide to find the best product to armour joint arrises on your project.

– Check the overall appearance of the trowel to see if there is any damage, cracks or deformation on the body. Focus on checking the trowel disc, trowel and connecting parts to ensure their integrity and firmness. – Check whether the tire pressure is normal and whether there is any damage or bulge on the tire surface. Generally, the tire pressure of a ride-on trowel should be maintained at around 2-3 atmospheres. At the same time, check the steering system to ensure that the steering is flexible and the connections are not loose. – Check the engine (if it is a fuel engine) or the motor (if it is an electric trowel). Check whether the fuel level of the fuel engine is sufficient, whether the engine oil is at the normal level, and whether the air filter is clean. For electric trowels, check whether the battery is fully charged, whether the wire connection is firm, and whether the plug is damaged. – Check the transmission parts, such as the tension of the transmission chain or belt. The chain or belt should not be too loose or too tight. Too loose will result in insufficient power transmission, and too tight may damage the transmission parts. Also check for signs of wear and tear. – Check the sprinkler (if any). Check whether there is water in the water tank, whether the water pipe is tightly connected, and whether the nozzle is blocked. Make sure that the sprinkler can work properly to avoid quality problems on the concrete surface due to lack of water during the troweling process.   – Remove debris, large stones, steel bars and other objects in the work site that may damage the trowel or affect the troweling effect. – If the operation is performed on the surface of newly poured concrete, make sure that the slump of the concrete meets the requirements and that the concrete has been initially vibrated and leveled before the trowel is operated. Generally, the slump of concrete is more suitable between 30 and 50 mm. – Place the trowel on a flat, solid ground and put the gear lever in the neutral position. – Turn on the fuel switch and pull the choke to the appropriate position (if it is a cold start, the choke can be closed more appropriately; if it is a hot start, the choke can be closed less or not closed). – Hold the starter rope handle and pull the starter rope firmly and steadily to start the engine. After the engine starts, gradually open the choke to the appropriate position according to the engine's operating conditions.   – Confirm that the power plug is connected correctly and the surrounding environment is safe (no water, flammable and explosive items, etc.). – Press the start button to start the motor. During the startup process, pay attention to the operation of the motor, such as abnormal noise, vibration, etc. – The operator sits in the driver's seat, keeps his body balanced, and holds the steering wheel or joystick with both hands. The feet can be placed naturally on the pedals to facilitate the forward, backward and steering control of the machine. – During driving, the speed of the trowel should be reasonably controlled according to the size, shape and state of the work site. Generally speaking, the speed can be controlled at 0.5-1m/s in the initial troweling stage; in the fine troweling stage, the speed can be appropriately increased to 1-1.5m/s. At the same time, it is necessary to flexibly control the driving direction of the trowel through the steering system to ensure that the trowel area is fully covered without omission.   – When the trowel reaches the concrete surface, put down the trowel disc and trowel to make it contact with the concrete surface. During the contact process, pay attention to observe the working condition of the trowel to ensure that the trowel can act evenly on the concrete surface. – According to the degree of solidification of the concrete and the requirements of troweling, reasonably adjust the working parameters of the trowel. For example, for concrete in the initial setting stage, the speed of the trowel can be appropriately lowered to avoid excessive disturbance of the concrete surface; for concrete in the final setting stage, the speed can be appropriately increased to obtain a better troweling effect. – During the troweling process, it is necessary to keep the driving route of the trowel neat to avoid crossing, excessive overlap or omission. Generally, the troweling operation can be carried out by straight driving, circular driving or partition operation. – After the troweling work is completed, first raise the trowel disc and trowel to leave the concrete surface. – For fuel engines, gradually reduce the engine speed, then turn off the fuel switch and let the engine shut down naturally. For electric trowels, press the stop button to turn off the motor. – Put the gear lever in the neutral position and pull the handbrake (if any).   – During operation, if the trowel is found to have abnormal conditions, such as engine smoke, abnormal noise, or trowel out of control, an emergency stop should be performed immediately. For fuel engines, the fuel switch can be turned off directly; for electric trowels, press the emergency stop button (if any). After the emergency stop, the machine should be inspected and the fault can be eliminated before restarting. – Clean the dust, concrete residue and other debris on the trowel body. Use a damp cloth to wipe the surface of the body, focusing on cleaning the trowel plate, trowel, tires, transmission parts and other parts. – Clean the water tank (if any) and drain the remaining water in the water tank to prevent the water from breeding bacteria or corroding the water tank.   – Check the various parts of the trowel, such as the wear of the trowel, the tension of the transmission parts, the air pressure of the tires, etc. Deal with or record the problems found in a timely manner for subsequent repairs or maintenance. – Place the trowel in a dry and ventilated place to avoid direct sunlight and rain erosion. If it is not used for a long time, it is also necessary to maintain the machine according to the maintenance requirements for long-term storage.

  Laser leveling machine is an indispensable equipment in the construction industry. It is indispensable in the construction of large highways. In order to ensure the smooth progress of construction and the smoothness of the road surface, it is necessary to master the correct use of laser leveling machine. Secondly, you should read the instruction manual of the equipment before use, because this will make you familiar with the internal structure of the equipment as soon as possible, so as to achieve correct operation. The following laser leveling machine manufacturer will show you the correct use of laser leveling machine. 1. Laser leveling machine manufacturers explain from a professional perspective that it is important not to work under a load that exceeds the load that the machine can bear. The laser leveling machine should be used to the best of one's ability. As a laser leveling machine manager, when designating an operator, the laser leveling machine random data and operation manual should be handed over to the operator so that he can master the mechanical performance and operating procedures normally, and the relevant data should not be withheld at will. 2. Laser leveling machine manufacturers explain from a professional perspective that it is necessary to try to ensure the uniform addition and subtraction of the load of the laser leveling machine, so that the machine is in a relatively gentle load change. Specifically, it is necessary to add and subtract the throttle more evenly to prevent the ups and downs of the engine and working device. 3. Laser leveling machine manufacturers explain the scientific use of lubricants from a professional perspective. According to statistics, more than half of the leveling machine failures are caused by poor lubrication. Due to the precision of the various parts of the laser leveling machine, good lubrication can keep it in a normal working gap and a suitable working temperature, thereby reducing the degree of wear of the parts and reducing mechanical failures. Normal and reasonable lubrication is one of the effective measures to reduce mechanical failures. To this end, first, it is necessary to reasonably select lubricants. During use, neither low-grade lubricants nor other types of lubricants can be used as substitutes, let alone inferior products. Second, the quantity and quality of lubricants should be checked frequently. 4. Laser leveling machines should be maintained and repaired in a timely manner. Laser leveling machines will inevitably have various failures during use. Among these failures, some failures may have a very small impact on mechanical equipment, while some are more serious and may even cause major accidents of machine destruction and death.
