Hoists are used in various large-scale water supply and drainage, water conservancy and hydropower projects. They are used to control the lifting of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing.

I. Features:

1. The hoist consists of a motor, a hoist, a frame, a protective cover, etc.; it adopts a three-stage reduction method, with a screw pair for transmission, providing a larger output torque. The supporting steel frame of the hoist overcomes the unevenness of the civil construction, reducing the overall noise and vibration.

2. It adopts an outdoor long-time working motor with a protection grade of ≥IP55. The stroke control mechanism adopts the principle of a decimal counter, controlling the stroke error to 0.5%. The torque protection control works by generating axial displacement through the worm to trigger a micro switch, thereby protecting the electrical components.

3. Operation and maintenance are simple, enabling on-site and remote control operations.

Hoist

2. This series of hoists cannot be used for oblique lifting operations without special design.

3. The electric-hand dual-purpose screw hoist has no stroke limit device, relying on extreme operation protection. Manual hoists are equipped with positioning sleeves to control the lower limit position.

4. When the user provides their own gate, they should follow the dimensions of the lifting lug seat provided by our company. If the user designs the lifting lug seat themselves, please provide the relevant dimensions of the lifting lug seat to our company to prepare the lifting ear at the end of the screw.

5. The following should be declared in advance when selecting:

a. Total length of the screw, length of the threaded part, center distance of the sling points (for double sling point type)

b. Length of the extended screw part and whether there are any segment requirements, etc.

C. Special electrical control requirements

d. Whether a screw protection device needs to be added; if yes, provide the relevant drawings or layout drawings

e. Other special requirements

6. The basic layout drawing of the hoist is only for reference in water conservancy construction. If there are special requirements, our company can make changes, and the anchor bolts will be supplied randomly.

7. Lubricating oil is supplied by the user.

8. List of optional accessories (priced separately)

a. Screw protection device; pin shaft

b. Extended screw part

C. Special electrical control requirements

d. Modification of the basic part

e. Overload protector, digital display height controller

g. Other modifications different from our company's product series

9. The main technical parameters and characteristic values of the product shall be subject to the values provided by the company before ordering. If the sample dimensions are changed, no additional notice will be given.

10. The equipment weight is only for reference when the demander designs, and shall not be used as the basis for the user's receipt.
