How to Install a Winch? Winch Installation and Winch Testing

Electric Winch

The electric winch is used in operations such as lifting and towing heavy objects, erecting equipment, driving piles, and cold pulling reinforcing steel bars in industries such as construction, metallurgy, mining and weight lifting. The working environment that the electric winch can be applied to is: temperature -10°C ~ +40°C (when the ambient temperature is less than 00°C, before starting operation, the lubricating oil should be heated), humidity ≥85%, height is less From 1000 meters, there is no fire accident, explosion etc. 

Trailer Winch


The working grades of the lever used are M4 or M5; as each working degree increases, its rated drag should decrease by 20%. After purchasing an electric winch, there is a big problem, which is how to install the electric winch and test the electric winch. Don't worry, now I will teach you how to install an electric winch.

A Guide on How to Install the Winch

When installing, disassembling and moving the electric winch, it is necessary to keep it stable and not tilt excessively without any collision and severe vibration.

Installing the Electric Winch and Inspecting the Winch

The electric winch must be installed by specialists. The floor intended for installing the winch must be level and very solid. The relationship between the winch and the base should be reliable.

·         When mobile use, install the crane on wooden beams, and connect the wooden block and structure reliably and securely to the ground anchor with steel wire rope. Pay attention to avoid any loosening.

·         Concrete measurements for installation should refer to conditions such as soil quality, soil specific gravity and ground bearing strength, and are determined by standard images of ground stabilizers suitable for local use.

·         When using in a fixed place, make concrete foundations, find the horizontal lines with the stepper, and pre-leave a square pit with a section of 20 x 20 (cm²). The number of pits is determined by the foundation. Winch screw (see Figure 2). First, install the foundation nail, then inject concrete into the holes; after bonding, tighten the nuts evenly. If there are rooms between the frame and the lower fascia, add an adjustment mat to prevent the frame from being partially deformed. The foundation pit depth should be determined according to the local geological condition and the type of electric hoist.

 

·         The electric hoist operating in the air must be protected by a rainproof canopy, which cannot obstruct the operators' vision and the operators must be able to see the leaders and pull objects.

·         The metal casings and electrical appliances of the electric winch must be evenly connected to the ground. The resistance to contact with ground should not be more than 4 ohms. The selection and installation of grounding devices must comply with the requirements of GB/T 232.

·         When used to lift heavy objects, the electric winch should be installed with an ascending switch above the travel limit.

·         The use of a toothed pulley is prohibited when selecting a guide pulley.

·         The number of safety circles for the steel wire rope on the winding drum should not be less than 3 circles. The end of the steel wire rope must be securely fixed. In order to ensure safety, the distance from the outer layer of the steel wire rope to the outer edge of the side plate of the winding drum must be no less than the diameter of the steel wire rope.

·         The connection area between the brake block and the brake wheel must not be less than 80% of the total area. When loosening the brake, the brake block should be completely separated from the brake and maintain a certain clearance. The clearance value is 1～2.5mm between the brake belt and the brake wheel, 0.25～1mm between the brake block and the brake wheel.

How to Repair your Marine Toilet

Most problems with marine toilets stem from a lack of basic maintenance, or attempting to flush bulky foreign materials through the system. Keeping an eye on the common problems listed below will help keep the system running reliably. Water Leak Leaks next to the pump handle on popular Jabsco and Raritan models are common in a unit that has not been maintained for some time.  The good news is that the water leaking here is seawater used for cleaning - so you don't have to worry about it posing a serious health risk. It's also usually easy to fix - the problem is almost always a worn or worn seal around the rod to which the pump handle is attached. Simply loosen the large plastic nut on the top of the pump to reveal the old seal – it usually takes 10 minutes to replace. Calcification One of the most difficult problems to diagnose is the outlet tubes becoming gradually clogged with calcium deposits. Because this problem emerges slowly, it is very easy to fail to detect ear
