一、轻小型起重设备　　轻小型起重设备的特点是轻便、结构紧凑，动作简单，作业范围投影以点、线为主。轻、小型起重设备，一般只有一个升降机构，它只能使重物作单一的升降运动。属于这一类的有：千斤顶、滑车、手（气、电）动葫芦、绞车等。电动葫芦常配有运行小车与金属构架以扩大作业范围。
二、桥式起重机　　
桥式起重机的特点是可以使挂在吊钩或其他取物装置上的重物在空间实现垂直升降或水平运移。桥式起重机包括：起升机构，大、小车运行机构。依靠这些机构的配合动作，可使重物在一定的立方形空间内起升和搬运。桥式起重机、龙门起重机、装卸桥、冶金桥式起重机、缆索起重机等都属此类。
三、臂架式起重机　　臂架式起重机的特点与桥式起重机基本相同。
　　臂架式起重机包括：起升机构、变幅机构、旋转机构。依靠这些机构的配合动作，可使重物在一定的圆柱形空间内起重和搬运。臂架式起重机多装设在车辆上或其他形式的运输（移动）工具上，这样就构成了运行臂架式旋转起重机。如汽车式起重机、轮胎式起重机、塔式起重机、门座式起重机、浮式起重机、铁路起重机等。
四、升降机　　升降机的特点是重物或取物装置只能沿导轨升降。升降机虽只有一个升降机构，但在升降机中，还有许多其他附属装置，所以单独构成一类，它包括：电梯、货梯、升船机等。除此以外，起重机还有多种分类方法。例如，按取物装置和用途分类，有吊钩起重机、抓斗起重机、电磁起重机、冶金起重机、堆垛起重机、集装箱起重机和援救起重机等；按运移方式分类，有固定式起重机、运行式起重机、自行式起重机、拖引式起重机、爬升式起重机、便携式起重机、随车起重机等；按驱动方式分类，有支承起重机、悬挂起重机等；按使用场合分类，有车间起重机、机器房起重机、仓库起重机、贮料场起重机、建筑起重机、工程起重机、港口起重机、船厂起重机、坝顶起重机、船上起重机等　厦门旧中央空调回收，厦门旧中央空调回收厂，厦门旧中央空调回收中心合环保的要求。　采用间歇式压差回油方案，简洁、运行可靠。新压差回油方案：集油时，高压电磁阀关闭，压力平衡电磁阀打开，油自蒸发器通过单向阀流至集油器。回油时，压力平衡电磁阀关闭，高压电磁阀打开，利用高压将油压回压缩机。通过时间继电器控制电磁阀动作实现间歇式回油。
商用中央空调行业发展综述　　商用空调在世界上已有百年的发展历史，在中国也有20多年的应用时间，然而真正引起国内企业关注还是近几年。目前国内市场家用空调领域竞争已经进入白热化阶段，随着价格战连绵不断，在家用空调领域几乎已经无利可图的企业纷纷开始在中央空调领域寻找新的发展空间和利润增长点。　　2003年商用空调（含户式中央空调）市场容量将达到85亿元，2005年达到200亿元以上。市场空间迅速巨大，而利润至少是40%以上。这对于众多在市场上艰难逐利的企业，尤其是仍在价格战中挣扎　2.制冷设备：中央空调，100冷吨-600冷吨中央空调：水冷机组、离心机、活塞机、螺杆机组，风冷热泵机、水冷柜机、地源热泵机组，溴化锂制冷机组；

(2) recycling 10-600 horse central air conditioning, water-cooled units, air-cooled units, etc.
(3) recycle and related equipment (air conditioning compressor, water cannon, towers, tanks, snake pipe and the basin ancient fan, the wind counters, etc.)
recycling domestic commercial central air conditioning, 1-10 horse packaged air-conditioner, wall hang up, chuangshiji etc. such as: daikin, mitsubishi, panasonic, haier, gree, chunlan, sharp, hitachi, aokema etc. all sorts of refrigeration equipment such as: refrigerators, freezers, display freezers, refrigerator, refrigeration freezing ark and cold storage. chunlan air conditioning, gree air-co, haier air conditioning, mitsubishi air conditioning, matsushita air-conditioner, hitachi air-conditioning, lg air conditioning, tcl air-conditioner etc pinpaiji. both at home and abroad, have the production and sale of the water source &heat pump unit more for dry type system and full liquid type system. dry type system energy-efficiency ratio low, and filled with liquid type system exists level control difficult and return oil difficult disadvantages. falling film type system integrated with dry and full advantages of liquid type system, not only realize efficient, especially applied the new pressure differential return oil way more stable and reliable. falling film type all heat recovery water heat pump technology by falling film type evaporator achieve efficient operation, compared with flooded chillers just less refrigerants filled volume, the environmental impact of smaller, adopt double tube and shell condenser realize unguided while recycling condensing heat compltely tries to use, in order to provide life with hot water. and that the traditional way is to adopt double heat exchanger series-parallel work, or in the engineering system implementation. double heat exchanger system control complex, poor reliability, engineering system realizes the recovery of hot water slightly lower grade. but this project uses double over heat exchanger achieving thermal recovery will overcome the above shortcomings. adopt double bundle tube and shell condenser guarantee cooling water and recovery of life water independent operation, free switching and mutual pollution, perfect realization all heat recovery function. adopt falling film type evaporator improving the unit operation efficiency, improved maintenance performance. improve the cooling performance coefficient (eer); improve the heat transfer performance of the evaporator, reduce the material cost, falling film evaporator type heat temperature difference is small, can be appropriately increased water temperature difference, thus reducing the use of groundwater flow rate and water pump power consumption. easy maintenance: refrigerant water in the flow inside the canal, can cover, clear water by opening the lateral dirt, refrigerants filled volume small, the more accord with environmental protection requirement. adopt intermittent pressure differential return oil scheme, concise and reliable operation. new pressure differential return oil plan: oil gathering, high-pressure electromagnetic valve is closed, the pressure balance electromagnetic valve opens, oil from evaporator through check flow to grease traps. return oil, pressure balance electromagnetic valve is closed, high-pressure electromagnetic valve opens, using high pressure will hydraulic back compressor. through time relay control electromagnetic valve movements realize intermittent return oil.
commercial central air conditioning industry development review commercial air conditioning in the world has lasted for a century, the development history of china has more than 20 years of application, however, real time caused by domestic enterprises focus is in recent years. the current domestic market family expenses air conditioning field competition has entered into the white-hot stage, with the price war, in continuous family expenses air conditioning field has almost no profit in enterprises have started in central air-conditioning areas looking for new development space and profit. in 2003, commercial air conditioner (including door type central air conditioning) market capacity will reach 85 million yuan, in 2005 achieve 200 million yuan of above. rapid huge market space, while its profit is at least 40%. for many in the market hard profit of enterprise, especially in price war still struggling to 2) refrigeration equipment: central air conditioning, 100 cold tons - 600 cold tons of central air conditioning include water-cooled units, centrifuge, piston machine, screw units, air-cooled heat pump machine, water-cooled packaged air-conditioner, ground source heat pump units, lithium bromide refrigeration unit,
