Intelligent castor what are the accessories. Steering lock by the spring bolt lock bearing ( Four or two locking) Lock for fixed castor castor, can put the activity. Anti-wind cover to avoid winding shaft and the wheel and other materials with stents clearance, to rotate the wheels are free. Single wheel brake switch on the wheel axle sleeve or tire surface, with the hand or foot operated brake switch device. Seal to avoid turning bearing or bearing of single wheel into the dust, and maintain its lubricity, easy to rotate. Racks installed below the transport, can make its fixed in one position. The brake switch can lock steering device can be fixed wheel brake switch again. Other use castor production of caster and its environmental conditions usually use environment is set up under the state of the indoor environment, so try to avoid used under special circumstances, such as: high temperature, low temperature, temperature, acidity, alkalinity and salinity, chemical solvent, oil, or water and liquid direct contact with castor, that will reduce the castor efficacy. Shall not use, want to all sorts of different situations, respectively equipped with other reliable measures, such as the material of metal ware, the materials of the castor oil material and so on comprehensive balance, and want to consider some of the material can cause fouling on the ground. Appropriate bearing load product introduction may be bearing load refers to the use manual operation in a flat on the ground is easy to move in the general bearing, at the same time is able to work for a long time in the state of security for such handling general load, prior to calculate the total weight of carrying objects, and then press allowed by the weight to choose the appropriate castor. Usually occurs in only three of the four casters only force, so the total weight of the weight should be * 0 in theory. 8 for this ( Don't be too full meter calculate) 。 With four casters, the limits of the total weight = each ( 1 only) Castor allow bearing load * 4 * 0. 8, a mixture of different sizes of castor, please at the lowest bearing load that a castor as a benchmark, to calculate maximum bearing weight as a whole. Including steering arm, leverage, rubber fenders, locking pad, and other parts with a specific purpose.
