Description

MULTI-PURPOSE LOADER "

The present invention relates to a multi-purpose loader which is easy to attach and detach from a winch of the present invention. More particularly, the loader has an advantage of saving manpower. Especially, when a winch is connected and the object is transported up and down in a narrow place, The present invention relates to a winch type multi-purpose loader which can be conveniently operated and can be efficiently operated.

Skid steer loaders are small, high maneuvering vehicles that are generally used for various purposes. In particular, the maneuverability of the skid steer loader is improved by suitably adjusting the weight ratio on the front and rear axles in the loading and unloading situations. In order to maximize the control efficiency of the weight ratio, it is desirable to make the vehicle structure small, if possible. Therefore, in the conventional skid steer loader (referred to as a loader) shown in Fig. 8, the engine room is located at the rear portion of the vehicle, which is the rear position of the cockpit. When the bucket at the front of the vehicle is empty, the weight of the rear axle portion is about 70% of the total weight of the vehicle.

A durable, high-performance engine cooling system is needed to cope with the work environment and the bad conditions that will be encountered in the skid steer loader. Skid steer loaders are often used in places with significant foreign matter, dust, and other contaminants.

Therefore, it has excellent performance to perform work in a weak work environment, so it can perform various work in a small workplace.

Generally, the crane shown in Fig. 9 is a mechanism for moving an object, such as a tower crane, a crane having a derrick fixed on the ground, and a mobile crane installed on a frame of the vehicle. The vehicle crane includes a rotating block 101 that is rotated by the power of the engine, a boom mechanism 140 that is rotatably supported on the upper end of the rotating block 101, And a winch mechanism 130 for moving the hook mechanism 150 up and down. The hook mechanism 150 includes a derrick cylinder 160, a boom mechanism 140, and a hook mechanism 150. The auxiliary winch mechanism 120 is additionally mounted on an existing crane as an option and installed on one side of the main boom 141 to increase the height of the crane, thereby deteriorating the stability of the crane.

As mentioned above, there is a need for a device that can be easily used by being mounted on a loader having good maneuverability by utilizing the fact that it is difficult to work in a narrow place although the crane is advantageous.

Also. In the case of lifting or lowering objects inside the building, it is necessary to use an elevator or a separate facility, and a device that can be used without being installed in a narrow place.
