HS-VT系列手拉葫蘆的8大特點使其具備了高性能、高安全性又充滿了靈活性，巧奪天工，自成一派，讓您更輕鬆、方便的完成工作，大大減輕您的勞動強度。 1、齒輪：日本技術對稱排列高速同步齒輪，比普通葫蘆耐磨度增加一倍，轉動更平穩，手拉力更輕。 2、鏈條：更高強度的鏈條，對口處焊接精細，經過中頻感應淬火處理，符合ISO3007-1984國際標準鏈條技術；適應突發超重作業；拉鍊手感好，改變普通葫蘆只能垂直向下拉的弊端，能從多方向、呈45度角拉拽，適應範圍更大。 3、弔鉤：高強度足料足鉤，高級合金材料，使承受以外超負荷工作時不發生斷裂，只是逐漸變形，安全係數更高；鉤頭處安全的設計使貨物不會脫鉤。 4、極限開關：弔上弔下都有極限開關部件，防止鏈條超出，確保安全。 5、部件：主要部件都採用優質合金鋼，實施嚴格尺寸、質量檢查，保証每一部件的性能充分發揮。 6、機身：纖細，設計新穎，大方美觀，符合人體工程學。機身輕，工作活動界面小，適應環境廣。 7、噴塑：先進的噴塑處理工藝，裡外都挂塑，使用后表裡都嶄新如初。 8、罩殼：精鋼壓制罩殼，堅固中顯輕巧。 另外我公司還生產各種規格的鏈條，鉤子，起重滑車等。

HS-VT series chain blocks 8 characteristics make them have high ability and security, high agility, and this greatly reduced word intension.

1. Gear: they are innovated symmetrical arrayed high speed synchronous gears, and are made for international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving.

2. Chain: adopts high strength chain and high precision welding technology meet ISO3077-1984 international standard; fits for gusty overload work conditions; takes your hands a better feeling ; multi-angle operation(with45°) .

3. Hook: made of high –class alloy steel, it has high strength and high security; by using new design, weight will never escape.

4. Limit Switch: using limit switch components in designation to protect chain and ensure security.

5. Components: main components are all made of high –class alloy steel, with high precision and security.

6. Framework: slight design and more beautiful; with less weight and smaller work area.

7. Plastic Plating: by adopting advanced plastic plating technology inside and outside, it looks like a new one after years of operation.
