New CD1/MD1 Electric Wire Rope Hoists (Foot-Mounted wire rope hoist (2/1 or 4/1 rope reeving) are light and small-sized lifting equipment hoisting to satisfy the needs of lifting heavier cargoes. they are updated by traditional CD/MD electric wire rope hoists and keep the traditional advantage such as low price and high performance, the appearance is somewhat the same, but reliability and quality is improved a lot and are liked by more and more CD/MD hoists’ customers. New CD1/MD1 Electric Wire Rope Hoists adopt modular design which allows it to be universal in its application (can be used virtually anywhere) where loads, equipment or system parts/sections need/have to be lifted, moved or hoisted.

The universal usability is increased by the fact that the foot-mounted hoist can be rotated around the drum axis into any position---The hoist can be turned around its longitudinal axis into any required rope pay-off position. Supplied as an integral unit the hoist is simply installed using 4 bolts through the pre-drilled mounting holes. There is no need for complicated alignment of motors, gearboxes and rope drum, the heavy duty fully machined frame ensures all critical alignments are factory set. This Electric Wire Rope Hoist-Foot Mount can be mounted on foot, on wall or other fixed places from different directions of the hoist; and can be mounted either supported on top of a beam or suspended under a beam, and therefore has no trolley and cannot be moved across the beam. It can be double speed on hoisting and can also be controlled by inverter. All units feature ensure enhanced safety, precision control and productivity.

The trolley uses F series helical gear reducer drive unit on both sides of the drive wheel transmission torque through a six-rowed steel, big transmission torque and high reliability avoid flat key shear failure, and this transmission is in favor of the installation of hoist trolley mechanism. Hoist body no falling off cable--the cables are arranged in the electric wire rope hoists interior by various method in order to make more beautiful appearance and compact structure, hoist mechanism frame is square welded structure with high versatility, it can be quickly transformed into foot-mounted electric wire rope hoists, the modular design of the electric control box as the theme uses first class brand of electrical components, with wrong phase, default phase and over-current protection, if the power supply wiring is wrong, it can automatically stop the circuit and prevent accidents effectively, frequency control system also could be adopted at the same time and make it more flexible and controllable, lay type contact wire rope adopted is safe, reliable and with long service life.

Our Foot-Mounted wire rope hoists (Travelling type steel wire rope hoist 1/2 fall for single girder or monorail) are characterized by low noise, compact structure, omitting the intermediate shaft, The square appearance (it has its particular advantage for compact quadrate structure and simpler design) is easier to install and fix, the lifting mechanism use planetary gear adjust speed, making the structure compact, lightweight, installed in the hoist drum effectively reduce the dimensions of shell, square box structure changed appearance. All the components include equipment; two speeds/one speed of lifting and travelling; all motors with brakes; load limiter; end switches; galvanized rope; hook

Standard Headroom/Monorail wire rope hoist (2/1 or 4/1 rope reeving) is the Foot Mounted wire rope hoist/base Mounted wire rope hoist plus electric trolley, Designed to travel horizontally along a beam with a standard headroom configuration, for single girder applications, which also called Single Girder Trolley Hoist, single Standard headroom monorail design enables the hoist to operate directly under and parallel with the crane or runway beam. The hoist is suspended via drive trolley. Unique drive layout type, completely abandon the traditional form of the long drive shaft, realize extremely smooth transmission, These electric wire rope hoists with monorail electric trolleys are small sized lifting equipment, They are ideal for replacing an existing overhead crane hoist and provide the option of single or dual speed operation for applications where precision is key. What’s more, Standard headroom monorail hoist, of exceptional design complemented by assured and interchangeability quality components and examined on various quality aspects by our experts which prevents rope slackening and easy change of rope, with Easily accessible separate brake, motor, drum, gear box & panel unit it is a hoist that adopt square simpler design, features ultra compact and favourable dimensions to provide optimum room and clearance when operating in confined areas. Besides, This standard headroom wire rope electric hoist by ours comes complete with its own trolley and is available with 2 or 4 falls of wire rope, in other words, Reeving: 2/1 or 4/1.The 2 fall models are available with SWL from 1t up to 10t; and the 4 fall models with SWL from 3.2t up to 20t.

Altitude less than 1000m, Lifting height is 6m-30m, working duty is A3, ambient temperature is -20~40°C, Air relative humidity should not more than 85% (+25°C), non corrosive gases, high temperatures should not be lifting or toxic, flammable and explosive materials. The type monorail hoist is our most frequently ordered hoist in the lower Safe Working load, These hoists tend to be the most economic choice for many standard applications of material flow. The hoists feature two direct drive cross travel motors. The cross travel trolley is adjustable to suit various flange widths. Beside, we offer you every model in two versions. One with a single normal speed, which can satisfy normal application, the other one provides two speeds: normal speed and low speed.

2. Speed reducer
      The electric wire rope hoist use helical gear three stage reducer  (Third-class dead axel helical gear transmission structure is adopted) which uses planetary speed-down drive for high effective, low yawp long using life, Gear and shaft (The special long transmission shaft) are made by alloy steel and high carbon steel and through proper heat treatment to ensure its reliability, high mechanical efficiency and service life. Case and case cover with precise assembly and good seal are made of quality cast iron, the reducer is independent, so it’s easy to load and unload it. Permanently oil bathed 3 stage planetary speed reducer with heat treated bevel geared teeth for quiet operation. Box body and cover are made of cast iron to ensure hoist's good damping performance and reliable sealing. The planetary gear reducer is adopted to ensure high transmission efficiency.
 3. Rope drum
