(1) Before using the new medium concrete mixer, the system and components shall be inspected one by one and the necessary commissioning shall be carried out in accordance with the requirements of the concrete mixer operation instructions. When the truck runs empty, check the rotating direction of the mixing drum or blade, the operation and braking of each working device, and confirm that it is normal, it can be operated.
(2) Fixed concrete mixer should be installed on a solid pedestal. When used for a long time, the anchor bolts should be embedded; if used for a short time, the sleepers can be laid under the machine seat and leveled.
(3) For mobile concrete mixers, they should be mounted on flat and hard floors, firmly supported by square timber or brackets, and keep the horizontal tires free from force. If the service time is more than three months, the tire should be unloaded and properly stored at the end of the axle should be cleaned and rust-proof.
(4) For some mixers that need to dig hopper pits, the pit mouth should be compacted to prevent surface water from entering the pit. The bottom supporting surface of the feeding track frame should be compacted or bricked, and the back of the frame should also be supported by wood to prevent track deformation during operation.
