above head height. Air-powered lifting has proven to be safe, effective, economical and time saving, par- ticularly where there is a compressed air power source. J. D. Neuhaus (JDN), Witten, Germany, has a
world-renowned reputation for the supply of high performance air operated handling equipment for the toughest environments for individual loads up to 100 tons. The company also supplies air hoists designed for operating in light to medium engineering and general workshop applications. These products ensure workshop health and safety compliance for load capacities up to two tons, with hoists that have been manufactured to the same high standards as their heavier duty equipment. Two ranges of these general lower duty hoists are
available, including the JDN Mini series with models available for payload ratings of 125, 250, 500 and 980 kg. These are aluminium bodied units which provide optional lift heights of 3, 5 and 8 m with a six-bar air supply. These hoists also are equipped with a single top suspension hook, which can be used with an optional trolley mounting providing overhead rail suspension to accommodate manual powered traverse movements of suspended loads. A manipulator unit is also available in this versatile Mini range, which pro- vides both safe and efficient single handed operation of lift, lower, traverse and load positioning operations. Where more rugged, steel-bodied hoists are
required, the JDN Profi TI series incorporates four models in a lower load range rated at 250, 500 and 1,000 kg, plus a two-ton lift capacity unit. These models also provide single suspension hook mount- ing with three optional trolley mounts available to provide manual, reel chain on motorized traverse movements. These products are supplied as standard with 3-m lift heights, operating from optional four or six-bar air supplies. Where single hock suspension mounting is utilized
for any of the JDN hoists, then both oblique or hori- zontal pulling facilities can be utilized. The JDN products incorporate high performance
grease providing permanent lubrication for the patented vane motor design and planetary gearbox which ensures fail-safe starting with low maintenance and lube-free operation. This is complemented with a patented wear-resistant motor braking system for 100% duty rating and the elimination of downtime. The pendant control units supplied with these hoists provide sensitive, infinitely variable speed control for the precise positioning of loads. Filtered or piped air exhaust systems can be supplied, together with appro- priate alternative grease lubricant for hoist operations within food-grade related areas. The low-headroom hoist designs combine strength with fast, silent and reliable operation, even for operation within hazard- ous environments including dusty, dirty or even po- tentially explosive atmospheres, and at temperatures from -20C to +70C. ■
索和滑轮配合。气动提升机是安全、有效、经济且 省时的，尤其是在有压缩空气的情况下。 J D Neuhaus公司因生产满足最严苛的环境要 求、单机载重量多达100吨的高性能气动提升设备 而享誉世界。公司还生产满足小型到中型工程使 用和车间通用的气动提升机。这些产品可保证工人 在车间工作的健康和安全，满足2吨负载容量的要 求。这些提升机与公司所生产的重型设备具有同样 的高品质。
小负荷的普通提升机有两款，包括有效负载为 125、250、500和980kg的JDN迷你系列产品。 这款产品是铝合金机体构件，可在6巴的气压下满 足提升高度为3米、5米或8米不等的要求。这款提 升机还配备有单独的顶部悬钩，可用于高空轨道机 架，通过空中轨道实现悬挂载重的移动操作。在全 系列的迷你产品中还配备有操作装置，可实现安全 有效的举升、降低、移动和负荷配置的单手操作。 作为更加牢固的钢架提升机，JDN Profi TI 系列有4个低负载的型号，范围为250、500和 1000kg，最大到 2吨。这些型号也配有3个可选的 高空吊悬机构，可以提供手动或长链条机动摇臂移 动。这些产品的标配是在4或6巴的气压下，达到3 米的提升高度。
由于单钩悬架适用于任何一个JDN提升机，因 此，无论是倾斜或水平的牵引设备都可以使用。 JDN公司的产品将能够提供持久润滑效果的高 性能润滑油应用于专利的叶轮液压马达和行星齿轮 箱，保证自动防故障装置的低维护成本和免润滑操 作。专利的耐磨电动机制动器系统作为补充，实现 了全负荷额定值的运转，避免发生故障。提升机的 控制部分为货物的精确定位提供灵敏、无级变速的 控制。过滤或管道排气系统，添加合适的油脂润滑 剂，可以在食品级范围内进行提升机的操作。低净 空提升机的设计充分考虑到了强度、速度、静音和 可靠性等指标，甚至是在布满灰尘、肮脏、有害健 康、有潜在易爆气体的环境中工作，能够在从零下 20℃到零上70℃范围内进行操作。 ■
