The engine is the source of power, bringing power to modern society. While the engine must be started by a starter. The common starter is an electric starter that needs a battery to provide energy. Other starting methods like air starter, require an external system to provide energy. All of them rely on external power. Once it lacks external power, the engine is “dead”.
The mechanical starter is the ideal solution during the above situations. Cqstart spring starter, using a simple mechanical mechanism, stores the energy by compressing the springs and releases the spring’s potential energy by pulling the trip lever to turn the engine’s flywheel.
What is the mechanical spring starter?
A mechanical starter which stores the manpower energy by compressing the disc springs and releases the energy by pulling the trip lever. And then the drive pinion will drive the flywheel to rotate.
It is the ideal solution for a black start, mostly used in military, emergency rescue, firefighting, marine and some other conditions where require high reliability. It is also called mechanical spring starter, spring startup, hand starter, hand-operated spring starter.
How to fit a mechanical starter to the engine?
(1)Most of the flywheel housings have two bores. The electric starter has taken a bore. And spring starter can be installed to the other bore.
(2) If the engine only has one mounting bore, just remove the electric starter and install spring starter to the mounting bore when needed.
Advantages of mechanical spring starter.
Compared to an electric starter, the mechanical spring starter is maintenance-free. And compared to other means of starting, spring starter requires no external system such as battery, cable, air compressor, fuel tank and so on. Cqstart spring starter is waterproof, anti-corrosion, and produces no sparks. With natural anti-explosion structure, you can use it anywhere dangerous.

The Basic Composition Of Spring Starter
The spring starter assembly consists of four major parts: a disk drive mechanism, an energy storage mechanism, a release mechanism and a clutch mechanism. The figure below shows the basic structure of a typical disc spring energy storage motor.
The Main Work Process Of Spring Starter
The energy storage mechanism is the main mechanism of Cqstart spring starter, the main parts are disc springs and main shafts. Together with the components, they cooperate with, the following functions are realized. First, they can convert the aforementioned manpower input torque into an axial force. This force is compressed and turns into energy which is stored in the disc spring group. Secondly, they can convert the spring potential energy which is stored through compressing spring into torque output through the main shaft to form the power that drives the rotation of the diesel engine.
Detailed Operating Structure Of Spring Starter
The Releasing Mechanism
The release mechanism is a part of the operating mechanism for spring starter, its main parts are the lifting rod assembly and the releasing lever working chain. The operator performs two operations with the lifting lever and the releasing lever. The purpose of operating the lifter is to keep the releasing mechanism in a state of being ready for energy storage, in which state the rotation of the spindle will be limited in order to achieve energy storage of the spring. The purpose of operating the releasing lever is to cancel the limitation of the spindle rotation when the diesel engine needs to be started; and at the same time completing the discharge of the disc spring, the output torque of the spindle, and the starting process of the diesel engine. In that progress, the shaft drives the flywheel drive gear to rotate.
The Clutch Mechanism
The clutch mechanism is a mechanism that combines and disengages the movement of the spring starter and the engine. The main part is the flywheel drive gear, which generates axial movement by means of a spiral groove on the starter main shaft. When the diesel engine needs to be started, the main shaft rotating pushes it to move in the direction of the flywheel to achieve meshing with the flywheel ring gear. Conversely, when the starter is working and the diesel engine begins to rotate actively, the flywheel of the diesel engine drives the rotation of the flywheel for driving gear while moving it backward along the axis, disengaging engagement of the gears.
disc drive mechanism
The disc drive mechanism is a manpower input mechanism, and the main parts are the disc drive shaft and the transmission gear. It is the only way to convert manpower into spring energy. One of its functions is to determine the disk movement space and the angle required for the disk to make the operation convenient and comfortable. Secondly, it changes the direction of the input torque so that the axis of rotation conforms to the axis direction of the disk spring energy storage. Third, it can limit the reversal of the disc axis. And last, it is the radial support of the spindle and the axial thrust.
Easy Way to Start a Diesel Engine
Cqstart spring starter is easy to operate when there is short of electricity, which compares with other ways. When the diesel engine needs to be started, first needs to ensure that the diesel fuel supply system of the diesel engine works normally. Then pulling the lifting rod of the starter to make the releasing mechanism in the preparation state of energy storage, and using the rotating handle to rotate the starter disk in the specified direction for reaching the required energy storage state. And then, pushing the releasing lever in the direction indicated. After that, the diesel engine will be started.

Marine mooring chock has two types: deck mounted chock & bulwark mounted chock. The material is casting steel ZG230-450 normally. IACS approved quality to withstand all conditions. BV, ABS, LRS, DNVGL, RS, IRS, CCS, KR, NK is available. YSmarines could also provide you with a customized design with CAD drawings.
ISO13729 Closed Chock
The closed chock is made according to the standard of ISO 13729. It is normally applied for the ship which uses wire ropes. The radius of the closed chock surface was designed based on the bending ratio of rope through the chock of not less than twelve times the wire rope diameter. The closed chocks can also be classified into two types by its installation site including deck-mounted closed chock and bulwark mounted one.
ISO13728 Panama Chock
The Panama chocks are made according to the ISO 13728 standard and are normally adopted for ships passing through the Panama Canal, which are normally assisted by locomotives using steel towing wire. They meet normal mooring requirements and Panama Canal requirements. The nominal size the Panama chock is denoted by reference to the width of the opening, in millimetres, which are 310mm and 360mm. It can be classified as deck-mounted Panama chock and bulwark mounted one according to their installation site.
ISO13713 Mooring Chock
The mooring chock is made according to the ISO 13713 standard and is a type of ship’s mooring and towing fitting installed on the shipside to lead the mooring and towing rope from the ship’s inboard to outboard. The mooring chocks are normally adopted for ships which use nylon or other synthetic ropes rather than wire ropes considering the small bending ratio. It has two types depend on its installation including deck mounted one and bulwark mounted one.
Bulwark (EU Type) Towing Chock
Bulwark towing chock also known as EU type towing chock, is installed on the bulwark. It is made of cast steel. The surface of the towing chock is fine polished by 2-layer of shop primer anti-rust painting after sandblasting 2.5and well painted without any bur and the edge is to protect the towing ropes from broken during work. It is similar to NS 2589 chock, not often used in Asian ships.
DIN81915 Panama Chock
The Panama chock is made according to German Standard DIN 81915. The Panama chock, mounted on deck or bulwark, is closed chock which is used to control the position of mooring ropes. The material of the chock is GS-38 (material 1.0420) according to DIN1681 (cast steel). All the edges of the Panama chock must be ground smooth, especially where the rope is in contact with the chock. And it is required to be a blast and primed for the surface treatment. It is used for vessel, tug, cargo ship, military ship, industrial ships etc.
NS2587 Bulwark Mounted Mooring Chock
NS2587 bulwark mounted mooring chock sometimes also called NS2587 mooring pipe, follows the strict quality control system. Its surface is smooth without burs or sharp edges. It helps reduce the friction of the mooring rope. But this type of chock cannot satisfy the requirements of the Panama Canal Commission (PCC). For this chock, it has two optional nominal dimensions. Type A is a welded mooring chock. It is more often used in European countries than in Asia.
