Suitable for construction, mining lifting factory civil construction engineering, and small equipment installation.

Product advantage

1. Thickened drum, the whole shell grade is IP55 (can be customized according to customer needs), allowing use in the external environment.

2. The motor insulation grade is F, and the protection grade is IP54 or higher.

3. The service life of a sufficient solid copper motor can reach 1 million times. The high level of protection supports two-speed operation and provides powerful power.

4. An electric fast winch has a variety of uses and can be lifted vertically, horizontally, or inclined to pull heavy objects.

5. Four-axis hole three-speed gearbox rotation, with safety protection device, high safety, high precision.

How it works:

When the motor is started, the power is decelerated by the coupling through the reducer and drives the drum to rotate. When the motor stops, the electromagnetic brake also brakes synchronously to stop the drum. The positive and negative rotation of the drum should also follow the rotation direction of the motor, so the object should also rely on the motor to rotate, and cannot be reduced by its own weight, affecting the speed of decline.

Due to the use of a closed speed reducer and electromagnetic brake, the operation only needs hand-held button switch control, low labor intensity, stable and reliable work, and is very widely used in building construction models.

Use requirements

1. Rope capacity check: The nameplate of each hoist is marked with the rope capacity of a certain diameter wire rope, which must be paid attention to when selecting: If the diameter of the wire rope actually used is different from the diameter indicated on the nameplate, the rope capacity must be checked.

2. Before installing the hoist, determine the installation position according to the specific working conditions. According to the traction force and installation position of the hoist, add heavy objects or bury ground anchors at the rear of the frame to avoid heavy objects dragging the hoist during work.

3. Before the electric lifting winch is used, it is necessary to carefully check whether the components and bolts are fastened, whether the steel wire rope is firmly connected, the lubrication of each part, and set and connect the ground wire. Then carry out no-load test, positive and negative running test, each shall not be less than 15 minutes, pay attention to check whether each transmission component has impact vibration phenomenon; Whether the brake is sensitive and reliable, the slide of the wire rope during braking shall not exceed 300mm, such as the slide is too large, should be adjusted in time. After confirming that the machine is in normal condition, it can be put into formal operation.

4. In the use of the winch, at least three rings should be retained on the drum when the wire rope is released to prevent pulling off the rope head pressure plate, the traction direction of the wire rope should be at a right angle to the axial direction of the drum, and cannot be tilted, otherwise, it is easy to make the wire rope around and slip.

5. When the machine is running, it cannot be cleaned and refueled, and it is strictly prohibited to run under a fixed load. When the machine is found to be abnormal, especially if the brake is not working, it should be stopped for maintenance or adjustment. Remove hidden dangers and faults to ensure safety.

6. When the heavy object is lifted to the required height, two parallel bumpers should be inserted under the lifting plate to make the lifting plate fall smoothly on the bumper.

7. It is strictly prohibited to step on the brake to prevent the brake wheel from breaking off the brake and causing a major accident.
