Trolley caster installation tips

The trolley is a common handling tool for our daily production and life. It is divided into a wheelbarrow, a two-wheeled trolley, a three-wheeled trolley and a four-wheeled trolley according to the number of casters. Among them, the four-wheel plastic flat trolley has a wide range of use and is relatively simple to operate.


How do we properly install the cart casters when installing or replacing such four-wheel plastic flat cart casters?


First, according to the approved load of the trolley, the load of the plastic flatbed trolley is less than 300 kg, so the single wheel load of the caster can be about 100 kg. It is recommended to use a 4 inch or more caster, because the larger the wheel, the easier it is to push.


Second, according to the use of the trolley, if it is a quiet place in the floor paint workshop, electronic workshop or hotel, it is recommended to use a caster with a mute effect such as TPR or polyurethane.


Third, in the case of satisfying the above two conditions, it is necessary to confirm whether the mounting hole distance of the caster is the same as the mounting hole distance on the plastic flatbed. Because the installation pitch of conventional medium-sized casters on the market is 74mm*45mm, the mounting pitch of such plastic flatbeds is generally 84mm*71mm. If the medium-sized casters do not find a suitable mounting hole, they can also be replaced directly with heavy-duty casters, because the mounting pitch of heavy-duty casters is the same as the mounting hole of this plastic flatbed, but the price of heavy-duty casters is more expensive than that of medium-sized casters. Some, but the quality is much better.


Fourth, when installing such a caster caster, it is recommended to use two directional wheels with two universal wheels, and the universal wheel should be installed on the side close to the handle. This method of installation is better at controlling the direction of the cart.
