Casters are an accessory device that is widely used in many devices and applications where movement is required. However, most casters available on the market are not equipped with hand brakes and may present some potential safety risks. The following are several disadvantages of casters not having a handbrake mounted.
Safety risk: after the hand brake is not installed on the truckle, the movement of equipment can be difficult to control, and the equipment movement speed is too high or too low, the untimely scheduling problem of brake is caused. Once the equipment is out of control, a potential security threat is posed to the operator and the surrounding environment. Particularly in hazardous environments, such as high-altitude or water operations, equipment runaway can have serious consequences.
Equipment damage: the casters lack of hand brakes during long-term operation, and may be constantly rubbed when the equipment is parked, accelerating equipment wear. Thus, without manual brake protection, the wheels of the device may be constantly rubbed for prolonged use, resulting in wear and damage, which may significantly reduce the service life of the device.
Maintenance cost increases: conventional maintenance of the equipment also adds cost if the casters do not mount handbrake. Because the equipment is difficult to control and to maintain stationary over a wide variety of terrain over a long period of time, the wheels and drives require more frequent maintenance and replacement, which increases the cost of equipment maintenance and replacement.
The labor intensity of personnel is increased: if the casters are not provided with handbrake, manual operation is needed when the equipment is stopped and started, which increases the labor intensity of operators, and discomfort or diseases of lumbar vertebra, cervical vertebra and the like can be caused, which affects the body health and the working efficiency of the operators.
