How to Fix Winch at Construction Site without Pre-embedded Foundation

Construction sites often encounter situations where site conditions are limited, making it impossible to dig pits for foundations or pre-embedded components, or where foundations are undesirable. In such cases, how should a winch be secured to prevent slippage, displacement, or overturning?

For winches without pre-embedded foundations, securing them requires utilizing pre-drilled holes in the base or using wire rope coiled around the base and anchored to the ground. A weight should be placed at the rear of the base. Simultaneously, the wire rope end should be pulled out from the bottom, and the center of the drum should be perpendicular to the centerline of the front guide pulley. Open pulleys should not be used for the front guide pulley; they should be fixed to ground anchors and not tied to vertical transport frames.

The pulley should be at least 8 meters away from the winch; for hoists with a lifting capacity of 3 tons or more, this distance should be at least 15 meters. The angle of inclination of the wire rope wound around both ends of the drum should not exceed 1.5 to 2 degrees.

For safety, when the lifting position is very low, the wire rope should not be completely released from the drum. In addition to the turns secured on the pressure plate, there should be at least three safety loops.

When installing a winch, choose a location that is slightly elevated, has a good view, and a solid foundation. Outdoor winches should be protected from rain and falling objects. Generally, a simple shed should be set up, and after installation, the winch should allow the operator to see the lifting and positioning of the suspended object.
