第一、手扳葫芦的体积较小，使用方便，且载荷量大，在进行电路铺设的过程中，若两地之间的距离较远，就需要用到手扳葫芦对电缆线进行拉紧工作，能够有效的提高工作效率。
Firstly, the spanner hoist is small in size, easy to use and large in load. In the process of circuit laying, if the distance between the two places is far, it is necessary to use the spanner hoist to tighten the cable, which can effectively improve the work efficiency.
第二、手扳葫芦实现对起重物的垂直吊运和水平吊运工作，线路大多铺设在地下或者是高空中，在施工时可以使用手扳葫芦对电缆线进行吊运工作，更加的省时省力。
Secondly, the wrench hoist realizes the vertical lifting and horizontal lifting of lifting objects. Most of the lines are laid in the ground or in the air. During the construction, the wrench hoist can be used to lift the cable, which saves more time and effort.
第三、手扳葫芦的安全系数较高，这款手扳葫芦采用双棘爪制动，安全系数较高，即使在作业过程中有一个棘爪损坏，另一个仍然可以继续支撑作业，可以使人们完成一项工作后对手扳葫芦进行维修，让人们有一段缓冲时间，在一定程度上，提升了工作的安全性。
Thirdly, the safety factor of the wrench hoist is higher. The wrench hoist adopts double pawl braking, and the safety factor is higher. Even if one pawl is damaged in the process of operation, the other can continue to support the operation, so that people can repair the wrench hoist after completing a work, so that people can have a buffer time, to a certain extent, improve the safety of the work.lizhu.37ix.com.cnshujun.37ix.com.cnfuheguann.37ix.com.cnwufangbus.07858.net tiexin.07858.net youxiang.07858.net
铝合金手扳葫芦在电力施工中发挥了很大的作用，是施工人员的好帮手，因此，我们要合理的使用它，以延长它的使用寿命。
Aluminum alloy wrench hoist plays an important role in electric power construction and is a good helper for construction personnel. Therefore, we should use it reasonably to prolong its service life.
