Product Description

Crane weld seam

The inspection standards for crane welds are mainly based on national mechanical industry standards, safety regulations for lifting machinery, and relevant norms for steel structures. They cover visual inspection, non-destructive testing (ultrasonic/radiographic/magnetic particle testing, etc.), and mechanical property testing. The inspection scope and qualified standards are differentiated according to the weld grade (grade one to grade three) and structural importance

Specification

Core criteria and test methods ‌

Youdaoplaceholder0 National standards and industry norms ‌ :

Chinese machinery industry standards (such as JB/T 4730 series) clearly stipulate the technical requirements for ultrasonic testing of welds in lifting machinery and the rules for defect assessment. ‌ ‌
1
The "Safety Regulations for Lifting Machinery" (GB 6067) stipulates that welds shall not have defects such as cracks and incomplete fusion, and shall comply with the bevel size standard (GB 985/986). ‌ ‌
2
The "Code for Acceptance of Construction Quality of Steel Structure Engineering" classifies welds into three grades. Grade one requires 100% ultrasonic flaw detection, Grade two involves random inspection of at least 20%, and Grade three only involves visual inspection. ‌ ‌

Key Configurations

Type of hoist
The small hoist is a kind of small mechanical equipment with excellent performance and extremely wide application. It is composed of a power unit and a frame. It is suitable for hoisting operations in high-rise buildings, such as hoisting various building materials and decoration materials.

Drawings & Dimensions

The patented product, the portable hoist (small hoist), is a small mechanical equipment with excellent performance and extremely wide application. It is suitable for hoisting operations in high-rise buildings, such as the hoisting of various building materials and decoration materials. Especially for long and wide materials that are difficult to move in corridors, such as wooden boards and woodwork boards, it has its unique advantages. At the same time, it can also be used for loading and unloading large workpieces on machine tools in mechanical processing workshops, production assembly lines in home appliance factories and food factories, as well as for lifting items in warehouses and households.

After Sales Service

The small hoist is composed of two parts: the power unit and the bracket.
The power unit is composed of an electric motor, a reducer, a clutch, a brake, a rope drum and a steel wire rope, etc. The motor is a side-magnetic single-phase capacitor motor and is designed with a braking mechanism when power is cut off. The motor is also equipped with a thermal switch to prevent it from overheating and burning out. The reducer is a two-stage gear reducer and is fixedly connected to the motor. The clutch, brake and fly tube are integrated. However, when the clutch is disengaged, a rapid descent can be achieved. Operating the brake can control the descent speed to avoid impact. The circular holes opened on the front of the power unit housing can be used to install a hair dryer. Users can equip a hair dryer as needed for forced cooling. The shell itself is equipped with a toolbox, which contains a clutch handle, a special wrench with a brake handle, a thousand-pound nut washer, a rod top cap, a button starter, a limit switch, wires and an instruction manual, etc.

Company Profile

Henan Mine Crane Co., Ltd. 

We are one of the largest and most professional crane manufacturers in China, with total sales of more than 1.6 billion US dollars last year, including sales of 11,000 sets of double-beam and gantry cranes, more than 73,000 sets of single-beam cranes, and more than 100,000 sets of electric hoist and accessories. 

The bracket part is composed of a main rod made up of a screw, a jack nut and a vertical rod, as well as a rotating arm. The rotating arm can rotate 360 degrees on the main rod. A limit switch is installed at the end of the arm to prevent over-position lifting accidents caused by operational errors or button malfunctions.
The operation button starter enables the motor to rotate forward and backward, allowing the steel wire rope to be wound and released. It can also lift and lower objects through the pulleys on the bracket to complete the lifting operation.

The small hoist is convenient to carry
The small crane series products are small in size, light in weight, exquisite and compact in structure, and easy to carry.
2. The small hoist is easy to install.
Place the power unit near the window (or balcony), assemble the bracket part, and insert it into the base hole of the power unit. It can be installed in 5 minutes.
3. The small hoist has a fast lifting speed, lifting 1 meter in 4 seconds and making a round trip to 10 floors in 3 minutes. When equipped with "special tools", the lifting speed is astonishing, and the higher the floor, the greater the advantage

FAQ

The small hoist has a wide range of applications
It adopts a 220-volt single-phase power supply and is used in various industries such as decoration companies, hoisting companies, installation companies, moving companies, factory workshops, repair departments, and storage warehouses, as well as in residential households. It also has a wide range of application sites. Besides being installed indoors, it can also be installed on rooftops. It can be installed on large-scale construction sites with corner scaffolding and can also replace gantry cranes for transportation in small-scale construction projects. It can install protective nets and billboards, and also carry out cast-in-place waterproofing projects on rooftops. It can repair Wells and pumps, store fruits and dry grains...
5. The small hoist is easy to operate and safe and reliable.
It takes only one hour to learn how to operate the machine. When an accident occurs during the operation according to this manual, the lifted object can touch the limit switch and the travel switch can be pulled to immediately cut off the power supply, ensuring the safety of the operation.
