The working principle of the calabash

　　Hand-lever calabash is an ideal tool for equipment installation, cargo lifting, object fixation, binding and traction, all kinds of functions are complete. Hand lever calabash is a small and small ideal hand lifting tool.

　　Working principle of lever hoist, lever hoist is obtained from human pull (handle) with the aid of lever principle and load matching line traction, the rotation effect on movement load within a block, drive the load operation. It can improve, pull, drop, calibrate and so on. If a particular device, not only can be used as a non linear drawing operation, and can be very convenient to choose the appropriate operating position, or in small tonnage machinery exponentially expand its load capacity, load a number of machines can be used for large tonnage joint operations.

　　Special aluminum alloy on top tightener and lever hoist, ratchet tightening device, catenary tightener, because of small volume, light weight, easy to carry and is widely used in railway catenary, transformer substation, high altitude wiring, communications companies adjust circuit, etc. Operation without power supply, using the lever principle, aluminum alloy rival chain hoist, lever hoist phase can easily realize the tension of the object, lifting machinery installation lever hoist will also can choose a better Angle should be hung hung goods, on the specified location, efficient operation. Hebei yu diao lifting equipment technology co., LTD adhere to the professional technology, service, after sales services to timely and populist, patient want to customers think, do not do, normal product inventory quantities, can achieve 72 hours fast delivery, free provide engineering solutions.
