Lift in the garage. Personal transport

When I bought a used car and began to repair it, my first assistant in the garage was ... a lift that I built under the ceiling. Without him, I would hardly have succeeded, for example, in such a difficult operation alone as replacing an engine.

Figure 1 shows the location of the lift in the garage - just above the hood of the car. With a boom length of just over a meter, my crane has a working area of about 5 m2. This is quite enough to remove heavy components and assemblies from it and return to its place during maintenance or repair of the car.

Rice. 1. Lift in the garage: 1 - ceiling, 2 - M16 bolts (4 pcs.), 3 - boom, 4 - cargo winch

I made a crane according to the scheme of an inverted jib (Fig. 2): an L-shaped boom-console with a cargo winch is planted on a vertical shaft.

Rice. 2. Crane design (click to enlarge): 1 - shaft, 2 - shaped nut, 3 - cotter pin, 4 - washer, 5 - glass, 6 - plain bearings, 7 - base, 8 - brace, 9 - corners 50x50 mm, 10 - spacer, 11 - thrust bushings, 12 - limiter bolt

The shaft was machined from a steel billet Ø 80 mm, welded into the base - a steel sheet measuring 400x400x25 mm and attached to the ceiling with four M16 through bolts. The floor slabs in my garage are slanted towards the entrance, so to keep the base horizontal, I put a few washers under the long bolts.

The arrow was welded from a meter-long brace, two corners 50x50 mm and a glass. In the latter, I pressed two bronze bushings, which serve as plain bearings. On the shaft, the entire structure is held by a splinted shaped nut M42x2,0.

As a cargo winch, it would be possible to use a manual hoist or a factory-made chain hoist. However, I made myself a winch myself (Fig. 3) - from a mechanism designed to adjust the air brakes of trucks (with a ratchet).

Rice. 3. Cargo winch with trolley (click to enlarge): 1 - wheel (4 pcs.), 2 - trolley cheek, 3 - roller, 4 - bearing No. 204, 5 - retaining rings, 6 - M12 bolts, 7 - drive handle , 8 - winch, 9 - pulley with load hook, 10 - flange

The central hole of the worm wheel was bored out for a cable drum - a piece of pipe Ø 42 and a length of 150 mm; welded this pipe. Then I put flanges - rings Ø 80 and 5 mm thick. Attached the drive handle to the input shaft of the ratchet.

I drilled holes in both halves of the drum, where I brought out the ends of a steel cable Ø 4 mm, hung a single-strand pulley with a cargo hook on it. If you turn the handle, the drum winds the cable and lifts the load on the hook to the desired height.

The winch thus obtained I supplied with a four-wheeled trolley. It consists of two curved cheeks with rollers, on which bearings No. 204 are put on with wheels pressed on them. The latter are held on the rollers by spring retaining rings.

The trolley moves along the horizontal shelves of the corners, and it is protected from jumping off by a limiter bolt with thrust bushings installed at the end of the boom.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Texas Instruments releases library for MSP430 and CC1100/CC2500 22.03.2007

One of the areas of application of the low-power MSP430 microcontroller is short-range wireless applications operating in the 433, 868, 2400 MHz ISM bands.

The radio part in such applications is often based on the well-known Chipcon CC1100 and CC2500 chips for frequencies up to 1 and 2,4 GHz, respectively. The combination of MSP430 and CC1100/CC2500 allows you to create high-performance wireless connections with speeds up to 500 kbps.

To facilitate interoperability between these products, Texas Instruments is releasing an open library of functions that avoids developing low-level interfaces when adding Chipcon wireless chips to a project. Interaction with Chipcon microcircuits is traditionally carried out through the SPI interface.

Texas Instruments provides this library for all SPI implementations on MSP430 peripherals: USART0; USART1; USCIA0; USCIA1; USCIB0; USCIB1; USI; Bit-banging (emulation) with GPIO. The library is provided with a demo application - LED remote control.
