Rubber timing belt height limit device: After the hook is lifted to the specified height, it touches the limit weight and turns on the travel switch. The “over-winding” indicator light is on at the same time, the hook is lifted off, the boom is extended, The boom is controlled to wait for the operation to ensure safety. After the production of the endless flat belt is completed, due to the use of the environment or conditions, when the endless belt must be used, the flat belt will be restrained by vulcanized joints, and the operation will return to normal.
In special occasions, if you still need a small amount of over-winding operation, you can press the release button on the meter box, and the limit function will be released at this time, but the operation at this time must be very careful to prevent accidents. Outrigger locking device: When an unexpected accident occurs and the high-pressure hose or tubing leading to the vertical cylinder of the outrigger breaks or is cut, the two-way hydraulic lock in the hydraulic system can close out the pressure oil in the two chambers of the outrigger and the outrigger.
Retract or throw out to ensure the safety of lifting operations. The pattern rubber conveyor belt from https://www.sjbelt.com/ is an oblique conveyor belt composed of a covering rubber with a working surface and a covering rubber with a flat non-working surface and a belt core. There are "herringbone" patterns on the belt surface that are higher than the belt body. The patterns can be open or closed. Each pattern can be divided into three types: high, medium and low. Rubber timing belt lifting indicator: The lifting indicator is set on the side of the basic arm (that is, the right side of the control room). The rubber conveyor operator can clearly observe when sitting in the control room, and can correctly indicate Elevation angle of out boom and rated lifting weight promised by the crane under corresponding working conditions.
After the production of the endless flat belt is completed, due to the use of the environment or conditions, when the endless belt must be used, the flat belt is vulcanized (also known as hot-stick) to make it become an endless belt. Lifting characteristic table: It is set on the lower wall panel in the front side of the control room. This table lists the rated lifting weight and lifting height under various arm lengths and various working ranges for easy reference during operation. When lifting, do not exceed the value specified in the table.
