Description

Super long arm unpowered crane

technical field

The utility model relates to a hoisting device, in particular to a super long-arm non-powered crane.

Background technique

Cranes are commonly used lifting equipment. Usually, the crane is powered by an electric motor, and the car-type crane is powered by the engine on the car, so there are certain limitations. In the absence of electricity, the motor cannot be used, and in areas with poor roads, it is difficult for a car crane to enter. In addition, the operating range of the crane is usually limited, generally within a dozen meters.

The utility model is aimed at the problems mentioned above, and the ultra-long-arm unpowered crane adopts manpower to work without other power. The boom is super long, the working range is large, the equipment is detachable, and it is easy to carry and transport.

Utility model content

The purpose of the utility model is to provide a super-long-arm unpowered crane, which adopts manpower to work without other power. The boom is super long, the working range is large, the equipment is detachable, and it is easy to carry and transport.

The purpose of this utility model is achieved in this way: the utility model includes a column, a beam, a beam lifting traction rope, a lifting traction rope, a hook, a beam lifting pulley block, a lifting pulley block, a beam lifting manual ratchet winch, and a lifting manual ratchet Winch, counterweight, base and bottom wheels. The column is installed on the base, bottom wheels are installed under the base, the base can rotate, and a counterweight is placed on the base. The upper end of the column is equipped with a pulley, the beam is installed on the upper part of the column, and is hinged with the column. The outer end of the beam can rotate around the hinge point, and pulleys are installed at both ends of the beam. A crossbeam lifting manual ratchet winch is installed on the base, and the crossbeam lifting traction rope is drawn from the crossbeam lifting manual ratchet winch, bypasses the pulley at the upper end of the column, and is connected with the outer end of the crossbeam. A crossbeam lifting pulley block is housed on the crossbeam lifting traction rope between the crossbeam lifting manual ratchet winch and the pulley at the upper end of the column. A lifting manual ratchet winch is also installed on the base, and the lifting traction rope is drawn from the lifting manual ratchet winch, bypasses the pulleys at both ends of the beam, hangs down from the outer end of the beam, and the outer end of the lifting traction rope is equipped with a hook. The hoisting movement pulley block is housed on the hoisting traction rope between the hoisting manual ratchet winch and the pulley at the inner end of the beam.

The utility model adopts manual operation, and is suitable for application in occasions without electricity. The beams and columns are simple in structure, can be disassembled, and are easy to install. The length of the beams can be adjusted on the construction site, and long-distance material lifting can be carried out.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The part numbers in Fig. 1 are: column 1, beam 2, beam lifting traction rope 3, lifting traction rope 4, hook 5, beam lifting moving pulley block 6, lifting moving pulley block 7, beam lifting manual ratchet winch 8, lifting Manual ratchet winch 9, counterweight 10, base 11, bottom wheel 12.

Detailed ways

See Fig. 1, the utility model comprises: column 1, crossbeam 2, crossbeam lifting traction rope 3, hoisting traction rope 4, hook 5, crossbeam lifting movable pulley block 6, hanging motion pulley block 7, crossbeam lifting manual ratchet capstan 8, hanging Transport manual ratchet winch 9, counterweight 10, base 11, bottom wheel 12. Column 1 is installed on the base 11, bottom wheel 12 is installed below the base 11, base 11 can rotate, and counterweight 10 is placed on the base 11. The upper end of the column 11 is equipped with a pulley, the crossbeam 2 is installed on the top of the column 1, and is hinged with the column 1, and the outer end of the crossbeam 2 can rotate around the hinge point. There are pulleys at both ends of the beam. The length of the beam 2 can be installed in different lengths according to the needs of the site, and can be 10 meters to 50 meters long. Crossbeam lifting manual ratchet capstan 8 is installed on the base 11, and crossbeam lifting traction rope 3 draws from crossbeam lifting manual ratchet capstan 8, walks around the pulley on column 1 upper end, is connected with the outer end of crossbeam 2. Crossbeam lifting moving pulley block 6 is housed on the crossbeam lifting pulley 3 between the pulley of crossbeam lifting manual ratchet winch 8 and the column 1 upper end, by crossbeam lifting moving pulley block 6 and crossbeam lifting traction rope 3, control crossbeam 2 lifting. Lifting manual ratchet capstan 9 is also installed on base 11, and lifting traction rope 4 is drawn from lifting manual ratchet capstan 9, walks around the pulley at two ends of beam 2, hangs down from the outer end of beam 2, and lifts the outer end of traction rope 4 Hanging hook 5 is housed.
