What is a Rollator?

Lifting tackle is an important lifting tool. It has a simple structure and is easy to use. It can change the direction of the pulling rope and the moving or moving objects of the tackle and the tackle multiple times, especially the tackle consisting of the combination of the tackle and the hoist. , Masts or other lifting appliances are widely used in construction and installation operations. The product specifications are from 0.03-320T, the wheel train is from single wheel to pick-up wheel, and the crane has four types of hook, chain ring, ring, and hanging beam, which can be selected by users. Also for the Transformers Bo faction soldiers of the same name.

Chinese name

Pulley (pulley)

Main components

Wooden frames, pulleys, short shafts, and ropes

Pulley also known as lifting tackle (also a lifting machine)

The main components are wooden frames, pulleys, short shafts, and ropes, and the core components are pulleys. Rope winding around

The moving pulley can reduce the traction force and cannot change the direction of the pulling force; the fixed pulley can change the direction of the force but cannot reduce the traction force; the pulley group can both reduce the traction force and change the direction of the pulling force.

1. Simple lifting machinery for vertical lifting of heavy objects. It has a small weight and a compact structure. There are both manual and electric.

Manual pulley. The drag chain is pulled by human force, and the chain drum is driven by the worm and worm wheel to lift the heavy object. The self-made brake with load is adopted, and the braking torque is greater as the load is heavier, which is safe and reliable. The working range is a vertical line under the hook.

Nylon wheel aluminum plate lifting tackle:

Uses: Suitable for lifting pole tower, wire line, lifting equipment and live work.

Features: Light weight, good abrasion resistance of wheels, no damage to steel wire ropes and ropes. The forms are hook type, ring type, single door and double door.

Electric tackle. The gear drive mechanism, wire rope drum and hook pulley are driven by the motor to lift and lower the weight. The casing is a wire rope drum, which is connected with a motor and a gear transmission mechanism with a brake. The upper part of the middle casing has lifting eyes. After hanging, the heavy objects can be hoisted vertically. The trolley can also be hung on a running trolley to become a running load trolley, traveling along an overhead track, and transporting materials within the workshop or between the workshop and the workshop.

2. The pulley is divided into single-door pulley, double-door pulley and multi-door pulley according to the number of wheels. According to the connection method of the pulley and the hanging object, it can be divided into four types: hook type pulley, chain ring type pulley, ring type pulley and hanger type pulley. In general, small and medium-sized pulleys are mostly hook-type, chain-ring and ring-type, while large-type pulleys use ring-type and hanging-beam type. According to the contact between the wheel and the shaft, it can be divided into two types: sliding bearings and rolling bearings. It can be divided according to whether the splint can be opened. There are open block and closed block. The splint of the open block can be opened to facilitate the installation of the rope. Generally, it is a single-door block. It is often used as a guide block at the foot of the grilling rod. The pulleys are divided into fixed pulleys and moving pulleys according to different methods.

Easy to use and versatile, can be manual and motorized. It can change the direction of the hauling cable of the pulley and the pulley unit and lift or move heavy objects, especially the pulley unit composed of the pulley unit. It is widely used in construction and installation operations in conjunction with hoists, masts or other lifting machinery. . Mainly used in factories, mines, agriculture, electricity, building production and construction, docks, docks, warehouse machinery installation, cargo lifting, etc.
