The Hoisting gear Low technical content, low added value and low labor productivity. The output growth rate and profit growth rate of an enterprise are equivalent to the profit growth rate. Problems in product type, technology and service lead to the actual contribution rate of mining winch industry to domestic mining operation.
There are many forms of hoisting winch. The large winch indicator is shaped a bit like a clock face. The height is indicated by the rotation of the pointer. It is usually repaired by the manufacturer. Small and medium-sized crane indicator is relatively simple, usually through the crane. The gear driver drives the indicator to indicate the height. If the indicator is damaged, check the gears of the transmission components, replace the damaged components or add oil.
Failure protection of depth indicator: when the indicator fails, the power will be cut off automatically and the safety brake will be implemented.
The main function of the lift depth indicator is to indicate the position of the lifting container in the wellbore. If the depth indicator fails and the winch operator is unable to determine the position of the lift container, an additional lift depth indicator fail safe will be reached after the depth indicator fails. When the crane is cut off and the brake stops, the accident of full speed exceeding rolling and falling may occur.
1. Working temperature: - 20 ~ 50 ℃ humidity:
Weight: 1 kg
3. Size: 300 mm × 200 mm × 110 mm (length, width and height)
4. Power supply voltage: AC 220 V 10% 50 Hz 5%
1. After setting the parameters, the host has the power saving function. It doesn't need to be set up repeatedly and is easy to maintain.
2. It has four protection functions: deep fault protection, over speed protection, speed limit protection and over protection.
Speed or depth display.
4. When the deviation between the pulse signal received on the depth indicator and the pulse signal on the motor shaft is 15%, the alarm will stop automatically after 6 seconds.
