Narrow Space Telescopic Spider Crane with Folding Boom

A spider crane is a lightweight tracked mini crane that gets its name from its distinctive appearance. It has a long boom, a compact body, and multiple outriggers that allow it to maneuver around obstacles. Its retractable outriggers provide the crane with additional ballast and stability. This also means the crane can be parked on slightly uneven ground and can be lifted at an angle.

The spider crane rolls onto its tracks to a narrow construction area, and the rigger will then pop out its 3-4 outriggers and place them on the ground, adjusting the distance and height on the X and Y axes to ensure the crane is in contact with as much stable ground as possible. As mentioned earlier, the outriggers can be used to create more stability when operating on uneven or sloping ground, but the safest way to operate a spider crane is on level ground.

Typically, the weight of the load and the height of the lift will dictate how the outriggers should be extended to ensure the rigger has enough ballast. Many outriggers are operated by hydraulic systems, which also provide additional power to the lifting process.

Once safely in position, the rigger will do a safety check and complete the lifting safety paperwork before securing the load to the boom and lifting it. The 3 ton spider crane will then proceed to lift the load to its maximum capacity and height for the specific load.

You will see spider cranes being used extensively in the later stages of large high-rise construction. They can skillfully lift construction materials to higher floors of multiple floors during the construction of a building.

The main component of a tracked mini crane is the boom, which is usually made of steel. The boom is connected to the crane base via a series of pulleys and cables. There is a hook at the end of the boom that is used to attach the load to the crane.

The hook is operated by a hydraulic system that allows it to be raised and lowered. The 3 ton spider crane’s legs are also hydraulic, which allows the crane to get around obstacles and into tight spaces. Each leg has its own wheel, which helps the spider crane move over uneven terrain.
