Cranes, also called cranes, are generally used in bed breaking and mechanical heavy industry. Cranes can be divided into large cranes and small cranes. Large cranes are generally used in some large-scale projects, and small cranes are generally used in transportation industry and construction sites. Crane is generally composed of motor and reducer, and the operation method of crane is similar to that of automobile. There are many brands of building small cranes. Which brand is better? Let's take a look at the brand and principle first.

structure principle

1. The power unit consists of motor, reducer, clutch, brake, rope drum and steel rope. The motor is a paramagnetic single-phase capacitor motor with a power-off braking mechanism; The motor is also equipped with a thermal switch to prevent the motor from overheating and burning; The reducer is a two-stage gear reducer and is fixedly connected with the motor; Clutch, brake and flying tube are integrated, but when the clutch is in the disengaged state, it can realize rapid descent, and the descent speed can be controlled by operating the brake to avoid impact. The round hole in the front of the power plant shell can be used to install the blower, and the user can equip the blower for forced cooling as required. The shell itself has a toolbox, which contains a clutch handle, a special wrench with a brake handle, a jack nut washer, a rod top cap, a button starter, a travel switch, wires and instructions.

2. The bracket consists of a main rod and a rotating arm, and the rotating arm consists of a screw, a jack nut and a vertical rod. The rotating arm can rotate 360 degrees on the main rod, and the end of the arm is provided with a travel switch to prevent lifting accidents caused by operation errors or button failure.

The forward and reverse rotation of the motor can be realized by operating the button starter, and the winding and release of the steel wire rope can be realized, and the operation of lifting the object can be completed through some pulleys of the bracket.

main feature

1, the small crane is easy to carry.

Small crane series products are small in size, light in weight, small and exquisite, compact in structure and easy to carry.

2. The small crane is easy to install.

Put the power unit near the window (or balcony), assemble the bracket part, insert it into the base hole of the power unit, and it can be installed in 5 minutes.
