INTRODUCTIONS

           Davit cranes with welded steel construction and hot dipped galvanized are designed for affordable and simple lifting operation for shops with limited space, which also can be directly mounted at the bed of truck or trailer for easy product loading and unloading. Davit cranes are very simple use with maintenance free operation, whilst offering a robust, weather resistant construction suitable for lifting and lowering loads. What’s more, davit cranes can rotate 360 degrees to access items from all sides.

           Portable davit cranes consist of an angled beam pivoting over a vertical base mounted beam and with fixed or adjustable booms, they are available in portable or fixed units. They can be used with permanent or portable power units, incorporating a hand operated electric winch. Besides, you can move the davit around as needed by using independent bases all over your workplace or shop, but only needed one unit to get the job done.

           Small Davit cranes are complete with bolts, square base mounting plate for anchoring to concrete floor slabs or to existing structures. Operators can rotate manually by using the pivoting slew handle giving infinite 360° slew rotation. When not in use, just slew handle then they can be locked off to rear of base column assembly. One of the advantages is that davit cranes adopt electrostatic spraying for the stand surface, similar to automobile painting and have long  working life, which also have exquisite outlook and more attractive appearance than normal cranes. Our cranes are very suitable for any occasions and place, because they are available with permanently installed floor-mounted pedestal bases, inverted bases that recess into side-wall brackets or concrete floors for industrial  applications, as well as dolly-mounted pedestal bases for equipment loading. Besides, each davit crane is equipped with powered or manual winches. The high-quality manual lifting winch has a large capacity, which can up to 3.2Ton. The brake mechanism of winch automatically engages when the handle is not  being cranking. The winch is made from carbon steel, which has a corrosion-resistant finish.

           Davit cranes offer a wide variety of options and accessories to meet customers’ specific requirements and standards. Please make sure to look at detailed images for full details, choosing the different options and components according to your different needs. With regard to power supply, DC motor is directly connected to car battery and lever switch to meet demands of various occasions. Besides, on the end of wire rope, the quick disconnect anchor is provided and with a swaged ball fitting for quickly attaching or removing and with the per-drilled holes of base plate, they are much easier for mounting. What’s more, the maximum load capacity of davit cranes depends on cable thickness, boom position and length of cable being used.

           Steel davit cranes are widely applied for loading and unloading of goods in light duty trucks, vans, heavy trucks, caravans, cars, wagons, loading docks, platforms, farms, laboratory, supporting the use of emergency vehicles, warehouses, indoor and outdoor decorations, schools, field operations, construction hoists, loading length, assembly line, heavy card, loading bay, rescue vehicles, storage, vehicles that can replace the small jib, bridges and many other fields. They are very suitable for areas where no power and perfect for a wide variety of simple jobs where adjustable height and reach are not required. What’s more, they are also used extensively in the wastewater and construction industry and in areas where floor space and access is limited. 

          Davit cranes are also called vehicle-mounted cranes, the accessory supporting alternative small cantilever cranes, hydraulic vehicle-mounted mini cranes, mini truck cranes, DC confined space davit cranes, mini pickup hydraulic truck cranes, mini hydraulic swing lift cranes, pickup truck cranes, truck mounted cranes, new type mini crawler cranes, swivel davit cranes with winch, lift jib cranes, vehicle mounted cantilever cranes, davit cranes for boats, electric davit cranes, lorry cranes, derrick cargo cranes, mini cranes hoists for car and mini jib cranes.

 C.Electric Winch Hoist With Hydraulic Pump Type

All of the three types have their own advantages and disadvantages.
           Compared with other types, the Manual Winch Hoist Type has the price advantage, and is cost-effective. The structure of manual winch hoist type is simpler, it is convenient for customers to install and carry. What’s more, it is also easy for operators to change components and maintenance.
           Electric winch hoist type has some familiars with manual winch hoist type, because both of them use the winch hoist equipment to lift the loads. Actually, manual winch hoist type is more environmental than electric winch hoist type. It can save more energy and electric power for customers. Besides, it not only has low price, also have can save money when operated. However, electric winch hoist has stronger working ability. Because electric power is supplied to operate davit cranes, which can make the cranes work at a high speed. Electric winch hoist can lift the loads quicker than manual winch hoist and it also can work endlessly, because there is no need to rest like the operators who control manual winch hoist type.
           Hydraulic type is equipped with electric hydraulic control system, hydraulic rotary rack and hydraulic telescope structure. Hydraulic type davit cranes can achieve the goods up and down, rotation, lifting equipment, usually mounted on the truck. It is safer, because this system can warn workers about overloading. It makes the loads works become more reliable and secure.
           Both Electric winch hoist type and Electric winch hoist with hydraulic pump type are all electric (electric lift) and has electric winch which belong to Electric  Winch Hoist, the main difference for Electric winch hoist with hydraulic pump type is it has hydraulic pump, so the crane arm can be raised with hydraulic  pump. The standard model does not carry hydraulic pump, the crane arm can only be lifted by hand which normally called hand type (please do not puzzle with  manual winch), which is more laborious. The electric winch hoist with hydraulic pump type is only customized for the customers but not default. What we sell best is the on-board crane without hydraulic pump, the standard on-board crane is without hydraulic pump.
         Price: Electric winch hoist with hydraulic pump > Electric winch hoist >  Manual winch hoist

 

Others
           1.  Packaging
           At first, davit cranes are wrapped with bubble film first. Secondly, they will be put in to the wooden case or packed with the steel pallet.
           2.  As regard the after-sales service, engineers are available to service machinery overseas and third-party supporting is available, too.
           3.  There are various specifications for the davit cranes, such as rated voltage, rated power, length of wire rope, wire rope diameter, adjustable length, hoisting weight, boom height, boom length, rotating arm mode, electric source, size of base, color and many other figures.
           4.  It is the owner's or operator's responsibility to determine the suitability of the equipment to its intended use. So operators should study all applicable codes, manuals and regulations. Be sure to read the owner's manual supplied with the equipment before operating it.
           5. Other types according to ropes
